As the motive force behind Williams Fire & Hazard Control’s foam and dry chemical response applications, adequate supply and management of fire water resources are the backbone to any successful response effort. Whether drafting from natural water sources, or feeding off a facility’s positive pressure water systems to relay precious firewater over miles of hose, Williams’ DependaPower™ Series represents a high-performance offering of three primary pump configurations that are built to run tirelessly as they deliver to sustain both the large volumes and high pressures required when facing today’s largest Industrial Fire scenarios.

In providing a primary firewater source / relay pumping options/ submersible access solution / redundant backup for fixed systems / or for dewatering and water movements capabilities throughout your facility, the DependaPower™ Series is a proven workhorse that scales to the application - one that can AND HAS handled industry’s greatest challenges.


Based on EPA Tier 3 diesel-driven horizontal split case centrifugal pump package and built with the world class Caterpillar™ diesel driver and Patterson™ water pump, the standard 6040 model delivers an unsurpassed performance with a 10-foot (3 meter) lift of 6,000 gpm (22,700 liter/min) rating @ 150 psi net outlet pressure at sea level. As a result, these pumping systems are ideal for drafting water from various sources including freshwater, seawater and even brackish water, as well as for providing pressure boost in relay operations. The pump, driver, and built-in fuel cell are integrated on a modular independent skid. The skid can be incorporated with various transportation modes such as trailers to provide additional mobility.

Offering standard configurations built with popular features to get you up and running fast, an extensive list of optional features, accessories, and additional pump sizes allow great latitudes for customizing a pumping solution that will meet your most challenging water management needs.
