Benefits of technology

[0007] Another object of the present invention is to provide a portable high volume water pump which can be utilized in a water source such as a pond, pool, or on municipal pressure hydrants to boost output pressure.
[0008] Still, a further object of the present invention is to provide a portable, high volume pump which may be utilized in a water source having as little as two inches of water depth.
[0009] It is a further object to provide a pump that is simple in design and manufacturability and can be utilized in a plurality of applications.

Problems solved by technology

Many rural and even urbanized areas of the world are not outfitted with a constant supply of pressurize water with the dedicated purpose of extinguishing fires such as fire hydrants.
Unfortunately, these carry a very limited volume in which they can transport, are not always available in every community, and therefore may not provide the amount of water necessary to fully put out a large fire.
Local sources of water such as swimming pools, ponds, or lakes have the potential to be a great source of water for fighting fires, but providing a means of getting the water out of the pool or pond and onto the fire in the very swift manner and in sufficient volume necessary to salvage the burning object proves difficult.

Embodiment Construction

[0019] The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0020] Referring now to the figures, in particular FIGS. 1 and 2, a preferred embodiment of the water pump assembly 10 is shown comprising the main elements of a water pump 20, hydraulic motor assembly 30, and coupler 50 disposed therebetween. Water pump 20 (also shown in FIG. 3 for clarification purposes) comprises a pump housing 21, containing the high volume impeller rotatably supported therein. An intake screen 22 is attached to the bottom side of the housing by a plurality of fasteners 25 bolted through evenly spaced apertures in the intake flange 23 surrounding intake screen 22. The screen prevents large foreign materials from being drawn into the pump impeller during operation which could possibly cause damage to pump assembly 10.

[0021] Pump housing 21 further comprises a tangential pump output 27, which ter...

Abstract

A portable, fully submersible, high volume water pump, driven by a hydraulic powered motor is disclosed for rapidly supplying a large volume of water at useable pressures to an extinguishment operation involving a burning object or building, utilizing a local water source such as a pond, pool, portable basin, or municipal hydrant. The pump is fully portable and, in a preferred embodiment, used in conjunction with an extensible boom arm of a utility vehicle such as a fire engine. The pump can supply water from a source having as little as two inches of water depth and is simple in design and manufacturability.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 688,412, filed on Jun. 8, 2005. The disclosure of the above application is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to water pump assemblies. More particularly, this invention relates to a portable high volume water pump assembly for use in fire fighting operations. BACKGROUND OF THE INVENTION [0003] In emergency situations, such as when a building, vehicle or other large object catches fire, a matter of seconds determines not only whether the object is a total loss, but whether lives could be at risk. It is therefore imperative that personnel trained to put out the fire arrive on the scene as quickly as possible. Furthermore, they must be provided with the proper extinguishing supplies with which they use to sequester the fire, such as water. Many rural and even urbanized areas of the world are not outfitted wi...
