Based on the vast experience of Williams Fire & Hazard Control with suppressing industrial fires and mitigating other hazards, DEPENDAPOWER Submersible Pump continues the proven technique of applying overwhelming fire suppression power to control a dangerous situation in the shortest time possible.

The highly efficient hydraulic submersible pump is driven by a market leading diesel engine to pump water at a rate of 8,000 gpm (30,000 Lpm) from a water source as far as 200 ft (61 m) away with a vertical lift of 35 ft (10.6 m). This water flow can then be delivered to an on-board or separate boost pump where pressure is increased before sending to end-of-line devices.

The pump is available as either a standalone pumping system to feed a standalone boost pump, or as a pump combination with a DEPENDAPOWER boost pump. In either configuration, the water can be fed into large volume firefighting monitors such as the Williams Fire & Hazard Control Ambassador monitor, or sent over a long distance hose relay, substantially increasing the logistical efficiency at incident sites.

The submersible unit is compact and easy to deploy. The self-contained pumping system can be built on a base skid, a hookload skid, or a trailer for easy transportation. A large integrated fuel tank can hold enough fuel to run the pump for up to 8 hours (depending on configuration and use).

Every unit has a high strength integrated lifting rack which allows crane lifting with a standard 4-point lift that does not require a spreader-bar. Fabricated with structural steel and stainless steel fasteners, the DEPENDAPOWER Submersible Pump is designed to pump fresh water, sea water, or brackish water. They are tough pumping systems delivering years of worry-free operations with low maintenance requirements.

Firefighting experience and commitment to reliability are incorporated into the design of the control system. DEPENDAPOWER Submersible Pump and submersible/boost combination units provide a user-friendly, waterproof LCD control screen as a primary interface, advanced sensors, redundant control mechanisms, and emergency shut-down switches for safe and easy operation that does not require extensive training.

The standalone submersible pump is ideal if you already have a DEPENDAPOWER draft/boost pump. Weighing only 320 lbs (145 kg), the floating unit is equipped with ergonomically designed carry poles which allow two or four operators to carry the pump unit into hard to reach locations. The combo pump provides unparalleled pumping and boosting capabilities in one transportable package. An optional wireless controlled crane is also available to aid deployment of the floating unit.

Williams Fire & Hazard Control provides various options and customizations, such as noise reducing enclosures, solar charging, intake and discharging manifolds, transport modes, and lighting, to meet your unique requirements for specific applications.

Large volumes of water are usually the most critical resource in firefighting and many other hazard mitigation operations. However, water is not always readily accessible. This inaccessibility is especially true when the fire pump is greatly elevated above the water level, or when large tidal swings occur. The DEPENDAPOWER Submersible Pump provides the ability to move water from sources where a conventional fire pump is limited by drafting capacity.

The DEPENDAPOWER Submersible Pump is driven by a powerful diesel engine in a self-contained transportable package to meet the ever increasing challenges of today’s industrial firefighting
and hazard control operations. The floating submersible hydraulic pump can lift 8,000 gpm (30,000 Lpm) of water up to 35 ft (10.6 m) from a body of water with a positive discharge pressure to feed boost pumps or transport the water over a long distance through a hose relay.

With a maximum vertical lift of over 100 ft (30.5 m) at distances up to 200 ft (60 m) away, the DEPENDAPOWER Submersible Pump helps resolve problems of water accessibility.

In addition, the DEPENDAPOWER Submersible Pump, in standalone submersible, or submersible/boost combination, is perfect for dewatering operations in flood zones. The 8,000 gpm (30,000 Lpm) combination pump can easily be reconfigured to move water side by side. The hydraulic submersible pump can pump up to 8,000 gpm (30,000 Lpm) while the on-board priming system of the boost pump allows for simultaneous open-water pumping of up to 6,000 gpm (22,700 Lpm). At full flow, the single unit delivers up to 14,000 gpm (53,000 Lpm) of flow, setting a new industry standard for moving large volumes of water.
