The DependaPower Firewater Pumps are EPA Tier 3 diesel-driven horizontal split case (or overhung axial split case for the 1500 model) centrifugal pumping systems designed to pump large volumes of water in emergency response operations.  Through hoses or hose relays, the pumps move water at high flow rates to feed discharging devices to cool the fire, dissipate hazardous vapors, and carry chemical agents to extinguish the fire.  The pump, diesel driver, and integral fuel cell are built on a common independent modular skid.  The skid can also be built as a hook-loader skid or integrated onto a dual-axle trailer for great mobility and be easily detached for stand-alone operations.  The entire system is optimized for performance, mobility, efficiency, reliability and ease of use.  These pumps have low regular maintenance requirements and can be up and running with minimum training.

The DependaPower Firewater Pumps have proven track records as the workhorses in industrial firefighting operations.  They can and have handled some industry’s greatest challenges.  In addition, they are suitable as pressure boosting pumps for water accessed by other means, redundant water source for fixed systems or for dewatering flooding zones.  Several models and extensive options are available to meet the specific requirements of the customers.


  • Proven Track Record
    Williams Fire & Hazard Control has relied on these pump packages for decades in their extensive response efforts. These resources are a critical component of our Response and Rental fleets.
  • Reliability
    Williams Fire & Hazard Control and its clients have placed the Caterpillar diesel drive and pump tandems (featured on these pumps) into operation, running multiple pumps without shutdown over several months, while experiencing continued reliable outputs.
  • Ease of Use and Serviceability
    These packages offer a user-friendly operations interface, as well as low maintenance requirements. Typical field maintenance issues, such as fuel, oil, and filters, are minimal. Service partners are available globally for driver or service pump needs.
  • World Class Components
    Superior performance of 10 ft (3.05 m) lift at full flow rate, enables direct drafting from low level water sources where competing products fall short. Lift as high as 20 ft (6.1 m) with reduced flow and proper priming equipment.
  • Designed for Mobility
    Compatible with various transportation modes, these pumps provide a great deal of power in a portable package, offering mobility and stability for deployment into any land or marine based exercise.
  • Wide Range of Available Options
    Meet today’s most challenging water movement scenarios with a fully customizable pump package tailored to your unique specifications.

Optional Features
Note: Optional features must be selected before fabrication.

  • 12 V electric front and rear jacks with trailer mounted battery (trailer mounted only)
  • Hose racks
  • Belzona* Super Metal Glide T pump coating
  • Double mechanical seals, API plan 53 flush, with tank
  • Air-powered dry prime type system includes twin-disc clutch and hydraulic actuation kit
  • Sound attenuated pump enclosure

The adequate supply and management of firewater resources are the backbone to any successful response effort, and are a driving force behind WILLIAMS FIRE & HAZARD CONTROL foam and dry chemical applications. Whether drafting from natural water sources, or feeding off a facility’s positive pressure water system, relaying precious firewater over miles of hose can be challenging. WILLIAMS FIRE & HAZARD CONTROL DEPENDAPOWER Transportable Pumps represent a high-performance offering of three primary pump configurations that are built to run tirelessly as they deliver large volumes of water and sustain the high pressures required when facing today’s largest industrial fire scenarios.

Whether providing a primary firewater source, relaying pumping options, submersible access solution, redundant backup for fixed systems, dewatering or water movement capabilities throughout a facility, the DEPENDAPOWER transportable pump is a proven workhorse that scales to the application – one that can, and has, handled the industry’s greatest challenges.
