Description
RELATED APPLICATION
[0001] The present application claims the benefit of U.S. Patent
Provisional Application Serial No. 60/586,522, filed on Jul. 7,
2004 and entitled "Pump System Including Host and Satellite Pumps
and Method of the Same," the entirety of which is hereby
incorporated by reference.
TECHNICAL FIELD
[0002] Embodiments of the present invention relate to pump systems
that enable flow of a large volume of water. More particularly,
embodiments of the present invention relate to pump systems using a
main host pump that is fed by one or more submersible mobile supply
pumps.
BACKGROUND
[0003] There are many uses for a pump system that delivers a large
volume and flow rate of water, including municipal and industrial
fire fighting, potable water delivery, emergency response and/or
other disaster relief needs. Such instances may require large
volumes of water at a large flow rate, such as 5000 gallons per
minute (GPM) or greater. Typical water sources include lakes,
rivers, and bays. A water source, however, may not be conveniently
located or accessible relative to the area that needs the water.
For example, it is not uncommon that an area of need is far away
(e.g., miles) from the nearest water source. Thus, a pump system
designed to extract water from long distances and flow large
volumes of water over long distances is desirable.
[0004] Many current devices employ typical suction/discharge supply
pumps, such as a fire pump apparatus. Such devices, however,
exhibit shortcomings of limited suction lift and distances that
they can be use from an available water source. Still further, such
devices are limited in their vertical lift capability, or the
ability to pull water from a source that is lower than the device.
Most current design can only draft water into their pumps from
water sources that are less than 10-12 feet below their suctions.
While such devices might be suitable for their purposes, these
shortcomings illustrate there still is a need for an improved pump
system that can deliver a large flow of water over a long distance,
and that may have improved vertical lift for accessing a lower
water source.
SUMMARY
[0005] Embodiments of the present invention relate to pump systems
that enable flow of a large volume of water. More particularly,
embodiments of the present invention relate to pump systems using a
main host pump that is fed by one or more submersible mobile supply
pumps.
[0006] In one embodiment, a pump system includes a main pump,
submersible satellite supply pumps, a control system, and diesel
drivers. Preferably, the pump system incorporates a 5000 GPM or
greater diesel driven main pump. The main pump is fed by two mobile
hydraulically driven floating/submersible supply pumps. The supply
pumps can include driven by a separate engine. The pump system is
self-contained within an inter-modal style container.
[0007] In one embodiment, the pump system may be configured with a
hose reel module that includes large hose deployment and storage
equipment.
[0008] In one embodiment, pump system may be configured with an
additive agent (e.g., foam) or decontamination module, which
includes additive agent storage and deployment tanks.
[0009] In another embodiment, the pump system may be configured
with a booster pump module. Preferably, the pump system includes a
5000 GPM or greater pump without submersible pumps for use when
only in-line boosting is necessary.
[0010] In another embodiment, the pump system may be provided with
a water distribution module. Preferably, the pump system includes
fittings and manifolds necessary to set up a large flow system
using 12-inch hose.
[0011] In one embodiment, embodiments of the present invention
provide a transportation system module. Preferably, the pump system
may be transported using a deployment vehicle such as a roll-on
truck and/or hook-lift style trucks and trailers.
[0012] One embodiment can include a water discharge system module.
Preferably, the pump system can include large flow water monitors
as both fixed and trailer mounted styles.
[0013] In one embodiment, the pump system can include a submersible
remote pumping supply system with or without a host boost pump.
Such a system can supply water to an independent boost pump using
one or more submersible remote pumps.
[0014] In one embodiment, a system includes a main pump, and a
first engine to drive the main pump. The system also includes a
satellite pump coupled to the main pump by a hose, the satellite
pump being configured to be deployed into a source of water, and a
second engine to drive the satellite pump, wherein the satellite
pump delivers water from the source of water to the main pump.
[0015] In one embodiment, a pump system includes a main pump, and a
first hydraulic engine to drive the main pump. The system includes
a first satellite pump coupled to the main pump by a first hose,
the first satellite pump being configured to be deployed into a
source of water, a second satellite pump coupled to the main pump
by a second hose, the second satellite pump being configured to be
deployed into the source of water, and a second hydraulic engine to
drive the first and second satellite pumps. The first and second
satellite pumps are configured to deliver water from the source of
water to the main pump, and the second engine drives the first and
second satellite pumps to prime the main pump.
[0016] In one embodiment, a pump system includes a main pump, and a
first hydraulic engine to drive the main pump. The system includes
a first satellite pump coupled to the main pump by a first hose,
the first satellite pump being configured to be deployed into a
source of water, a second satellite pump coupled to the main pump
by a second hose, the second satellite pump being configured to be
deployed into the source of water, a second hydraulic engine to
drive the first and second satellite pumps, and a hydraulic control
system configured to sense water inlet pressure at the main pump
and to control output of the first and second satellite pumps. A
powered deployment and retrieval system is configured to deploy the
first and second satellite pumps into the source of water and to
retrieve the first and second satellite pumps from the source of
water, the first and second satellite pumps are configured to
deliver water from the source of water to the main pump, and the
second engine drives the first and second satellite pumps to prime
the main pump. The hydraulic control system is configured to
control the output of the satellite pump to create a positive water
pressure at the main pump.
[0017] Use of the satellite supply pumps to feed the host pump can
exhibit one or more of the following benefits. Generally, the pump
system allows the flexibility of not having to be close to water
sources. An operator can draw water to the main pump up to 200 feet
and 15 times farther away than could normally be accomplished with
a standard suction hose supply setup. The satellite supply pumps
increase the vertical lift capability up to 50 feet and up to 5
times greater than normal draft capabilities of a typical fire
apparatus.
[0018] Embodiments of the present invention may enable an increase
in the number and type of water supply reservoirs or sources that
can be tapped at one time to provide water for pumping. The host
pump can be placed farther away from the water source and still
provide large flow capability without significant degradation in
hydraulic efficiency and output.
[0019] A plurality of host pumps can be set up in series for
increased pumping distances. Embodiments of the present invention
can utilize a large diameter fire fighting attack hose that may be
suitable for potable water use.
[0020] The host pump unit can also incorporate a self-contained
hydraulic flow and pressure control system that prevents the system
from losing control, damaging itself or losing flow capability.
Embodiments of the present invention can include a dual engine
system, one engine for the host pump and another engine for the
satellite supply pumps. This configuration can help ensure that the
host pump does not operate in a dry condition. This configuration
also allows for flexibility in the use of the system. Embodiments
of the present invention can provide manual and automatic control
of a hydrostatic drive system for the submersible supply pumps,
allowing for increased system flexibility.
[0021] Further, embodiments of the present invention can provide an
electronically controlled management system for the main host pump,
which is designed to include an option for automatic foam
proportioning. The container structure allows for an inter modal
capability and system modularity, such as roll off, hook arm and
cable drag capabilities and interconnectability with other
connecting modules.
[0022] Fluids used in the system, such as foams, can be selected
according to their environmental impact. The pump system may also
include drip containment devices to prevent module fluids from
entering the environment.
[0023] These and other various advantages and features are
described in the following detailed description. Reference can also
be made to the drawings which form a further part hereof, and to
accompanying descriptive matter, in which there are illustrated and
described specific examples.

driven and driven by the second engine 68. The hydraulic pumps 66
may include a water over oil heat exchanger along with air-cooled
exchanger on a radiator. Preferably, a hydraulic reservoir having a
sufficient capacity (e.g., 150 gallons) may be included for use
with the hydraulic pumps 66. The hydraulic pumps 66 may use a servo
hydrostatic control system, which utilizes pressure sensing of
inlet water pressure and/or biased air pressure to control the
hydraulic power output to the submersible satellite supply pumps
60.
[0083] The second engine 68 may be provided with a hydraulic pump
driver control panel (not shown). The hydraulic pump driver control

[0086] FIG. 4A illustrates the pump system 10 ready for transport
to a site. FIG. 4B illustrates the pump system 10 being offloaded
to a site. The pump system 10 may be transported and offloaded
using a transport vehicle 90. As one non-limiting example
illustrated in FIGS. 4A and 4B, the transport vehicle 90 may be a
lift truck. The transport vehicle, however, may be any suitable
vehicle, such as a forklift, other lift truck, transport, platform,
crane, helicopter, rail care, ship, barge, etc.
[0087] FIGS. 5 and 6 shows the pump system in use. FIG. 5
illustrates the pump system 10 while in use on a surface 80 and
with a source of water 82. The pump system 10 is shown operated on
an incline surface 80 where the water source 82 is lower than a
position where the pump system 10 is disposed. A control panel 70
accessible through side door 20 enables control of the pump system
10. Supply hoses 72 are connected to the satellite supply pumps 60
at one end, and connected to the suction connections 56 accessible
through the side door 22 at the opposite end. Preferably, the
supply hoses 72 deliver water to a suction side of the container 15
back to the main pump 50. Hydraulic hoses 74 supply hydraulic
pressure to the satellite supply pumps 60. The hoses 74 may be
deployed by the hose reels 62, which may also be used as a powered
retrieval system of the hydraulic hoses and satellite pumps 60.
[0088] The control panel 70 may include total system control of the
pump system 10. Preferably, the control panel is provided with 304
SS powder coated steel construction, alarms and shutdowns located
on the left side of pump system 10, accessible through the side

[0089] FIG. 6 schematically illustrates a pump system 10b in use.
Similar components as FIG. 5 are denoted with the same numbers and
including the suffix "b." The pump system 10b also includes supply
hoses 72b and hydraulic hoses 74b connected in a similar
configuration with satellite supply pumps 60b. Similar to pump
system 10, the supply pumps 60b are carried in strainer carriages
61b. The supply pumps 60b are deployed in a water source 82b. FIG.
6 illustrates a preferred operating distance D between the water
source 82 and the pump system 10b. Preferably, the operating
distance D is at about 150 feet. The configuration in FIG. 6 shows
an elevational distance E allowing the pump system 10b to operate
from a level on a surface of the water source 82 to a level that
the pump system 10b is disposed. Preferably, the elevational
operating distance is about 50 feet, providing a vertical lift of
about and up to 50 feet. Thus, the pump system 10b and main pump
may be located on a hill, cliff or high dock, while the satellite
pumps may deliver water flow to the main pump.
[0090] FIG. 6 shows discharge hoses 76b that may be used for
delivering water flow from the main pump supplied from the
satellite supply pumps 60b and supply hoses 72b. The discharge
hoses 76b may supply to any desired end destination 85 and/or to a
fire fighting nozzle 100, such as a large flow firefighting nozzle.
An end destination may be any area needing water, such as for
potable water use, municipal and industrial firefighting, or a
disaster relief area.
[0091] In another preferred embodiment, a plurality of host pump
modules may be incorporated. As shown in the schematic of FIG. 6,
embodiments of the present invention may incorporate additional
pump systems 10' operating solely as boost pumps. The additional
pump systems 10' may be configured in series as a plurality of
boost pumps. Preferably, the series of boost pumps are spaced X
distance apart, where X denotes a number of miles between each pump
system 10'.
[0092] Embodiments of the present invention may also provide a flow
rate based direct injection proportioning system (not shown). A
proportioning system may be flow measurement based. The pump system
may be operated using a pumped additive supply (e.g., foam), such
as by incorporating a tanker having transfer pump. A bulk supply of
additive may be pumped from a bulk container into the suction side
of the pump system. Flow meters may display flow rates of the
solution exiting the pump as well as the flow rate of the additive
entering the suction manifold of the pump system. These flow rates
may then be compared to determine the percent injection that is
being achieved. The percent injection may be increased or decreased
by adjusting the rpm of the transfer pump that is supplying
additive to the pump system. Adjustments may be made based on
readings shown on flow meter outputs.
[0093] Illustrated as an example only in FIGS. 5 and 6, embodiments
of the present invention can provide the following operational
sequence. The pump system may be deployed by rolling off a delivery
truck using a cable drag deployment system. Doors are opened at the
rear of the container where two submersible pumps are stored.
Doors, when used, on each side of the container are opened up to
offer access to suction and discharge connections. The two
submersible satellite supply pumps are rolled out of the end bays
down ramps that may be pulled out from the floor of the container.
A quick connect retrieval cable can be attached to each submersible
pump. Each pump is rolled to the waters edge where an 8 inch water
supply hose is then connected to the discharge connection of each
submersible satellite pump. The 8 inch supply hoses are then
deployed from the satellite pumps and connected to the main pump
suction manifold connections. The floating submersible satellite
pumps are then rolled into the water. A pontoon system may then be
used to float the pumps into position in the water. The main pump
12 inch discharge hose may be deployed from the discharge
connections of the pump system to the next device in line (in line
use of FIG. 6). This device could be a large flow firefighting
nozzle or another pumping system operating as a boost pump or end
destination.
[0094] After completion of system set-up pumping may proceed. The
sequence of operation is as follows. (1) Start submersible
hydraulic pump driver and set rpm to about 1900 rpm. This will
drive a Servo hydraulic pump system that can sense a main pump
inlet pressure and speed up or slow down the submersible satellite
pumps as necessary to maintain adequate (e.g., 5 to 15 psi) water
pressure at the main pump inlet. The hydraulic pump can develop
adequate (e.g., 50 GPM at 5000 psi) hydraulic power at each
submersible satellite pump. This hydraulic flow and pressure shall
drive the submersible satellite pumps to create a 2500 GPM or
greater water flow up to the main pump. The hydraulic hose lines
may be sized accordingly to allow for about a 150 foot linear
deployment. (2) Switch hydraulic pump manual control to "ON"
position. This can engage the hydraulic pumps thus pressurizing the
hydraulic motors fixed to the floating submersible satellite pumps.
The floating pumps can begin developing pressure and pumping water
through the 8 inch feed hoses up to the main pump. (3) Read
pressure gauge at pump panel to confirm positive water pressure at
the main pump inlet of 10-psi minimum. (4) Switch Hydraulic Pump
Manual Control to "AUTOMATIC" Position. This can initiate the
hydraulic control system that will track main pump inlet pressure
and automatically increase or decrease submersible pump speed as
needed to continuously feed the main pump through its range. (5)
Start main pump and begin pumping to discharge device at desired
pressure. (6) Set electronic engine control to automatic mode. This
can initiate the electronic engine control system that may track
main pump discharge pressure and automatically increase or decrease
engine speed as needed to continuously maintain discharge.
[0095] More preferably, example embodiments are designed so that
the satellite pumps pump water into the main pump before the main
pump is started. For example, the second engine can be used to
drive the satellite pumps independently of the first engine and
main pump. The satellite pumps can deliver water to the main pump
to prime the main pump. This minimizes the possibility of the main
pump "running dry" (i.e., running without sufficient water).
Running dry is a condition that is advised against by pump
manufacturers, as it may result in damage to the main pump.
[0096] Referring now to FIGS. 7-9, an example embodiment of a pump
system 200 is shown. As shown in FIGS. 7A-7F, system 200 includes a
container 15' that is similar to system 10 described above. System
200 differs, however, in that system 200 does not include a main
pump or first engine to drive the main pump. Instead, as shown in
FIGS. 8A-8D and 9A-9B, system 200 includes only a satellite pump
60' and engine 68' to drive satellite pump 60'.
[0097] As shown in FIG. 10, satellite pump 60' of system 200 can be
deployed in a water source 82c to supply water to a separate boost
pump 250. A separate additive injection module 260 can also be
coupled to boost pump 250 to inject an additive into the water
supply.
[0098] Referring now to FIGS. 11A-1B, another example pump system
300 is shown. Pump system 300 is similar to system 200, except that
system 300 includes two satellite pumps 60'. As shown in FIG. 12,
satellite pumps 60' can each supply water from a water source 82d
to a separate boost pumps 350. Boost pumps 350 can, in turn, supply
water to a mobile fire fighting delivery device 370 through a
manifold 360. Additional details regarding example embodiments of
manifold 360 and mobile fire fighting delivery device 370 can be
found in U.S. patent application Ser. No. 10/926,736, filed on Aug.
26, 2004 and entitled "High Flow Mobile Fire Fighting System," the
entirety of which is hereby incorporated by reference.
[0099] Referring now to FIG. 13, satellite pumps 60' of system 300
are shown connected to a water pump 450, as described in U.S.
patent application Ser. No. 10/926,736. Water pump 450 is, in turn,
coupled to mobile fire fighting delivery device 370 using manifold
360.
[0100] Systems 200 and 300 are advantageous in that the satellite
pump(s) can be used to provide water to one or more separate main
pumps in a variety of configurations. System 10 can be utilized in
a similar manner through use of second engine 68 and satellite
pumps 60 (without the use of main pump 50 and first engine 40) to
deliver water to a separate main pump.
[0101] Embodiments of the present invention provide many advantages
over existing pump systems. Use of the satellite supply pumps to
feed the main pump has the following benefits. An operator can draw
water to the main pump up to 200 feet and 15 times farther away
than could normally be accomplished with a standard suction hose
supply setup. The satellite supply pumps increase the vertical lift
capability up to 50 feet and up to 5 times greater than normal
draft capabilities of a typical fire apparatus.
[0102] The design may enable an increase in the number and type of
water supply reservoirs or sources that can be tapped at one time
to provide water for pumping. The host pump can be placed much
further away from the water source and still provide large flow
capability without significant degradation in hydraulic efficiency
and output.
[0103] A plurality of host pumps can be set up in series for
unlimited pumping distances. Embodiments of the present invention
can utilize a large diameter fire fighting attack hose that may be
suitable for potable water use.
[0104] The host pump unit also incorporates a self-contained
hydraulic flow and pressure control system that prevents the system
from losing control, damaging itself or losing flow capability.
Embodiments of the present invention include a dual engine system,
one engine for the host pump and another engine for the satellite
supply pumps. This configuration can help ensure that the host pump
does not operate in a dry condition. This configuration also allows
for flexibility in the use of the system. Further, a separate
hydraulic pump driver, in this fashion, can operate all other
parasitic devices that may be used as well as carry its primary
function of priming and supplying water to the main pump. This
feature allows the pump system to supply water to either the main
pump or an alternate main pump. It also allows the pump system to
simply operate as a boost pump in series with a plurality of pump
systems. Thus, the water and/or additive solution may be pumped
over long distances. When in this boost pump operation, the pump
system does not require the use of the submersible satellite supply
pumps. Thus the satellite supply pumps can be stowed while not in
use.
[0105] Embodiments of the present invention provide manual and
automatic control of a hydrostatic drive system for the submersible
supply pumps allowing for unlimited set up variations.
[0106] Further, embodiments of the present invention provide an
electronically controlled management system for the main host pump,
which is designed to include an option for automatic additive
proportioning. The container structure allows for an inter modal
capability and system modularity, such as roll off, hook arm and
cable drag capabilities and interconnectability with other
connecting modules.
[0107] Fluids used in the system, such as additives, hydraulic and
coolant fluids are considered and selected according to their
environmental impact. The pump system may also include drip
containment devices to prevent module fluids from entering the
environment.
[0108] Having described example embodiments of the present
invention, modifications and equivalents may occur to one skilled
in the art. It is intended that such modifications and equivalents
shall be included with the scope of the invention.
