The rugged and reliable Waterous CR / CRU single-stage centrifugal fire pump provides the discerning pro a large capacity pump either pedestal-mounted (CR, CRU models) or with an optional chain-driven transmission (CRQA, CRQB, CRUQB). This CR end-suction pump has a water delivery rated at 2050 GPM @ 250 PSI (7800 L/min. @ 17 bar). The CRU end-suction pump has a water delivery rated at 2640 GPM @ 250 PSI (10000 L/min @ 17 bar). Like all of our pumps, the CR and CRU single-stage centrifugal fire pumps are tested at full power prior to shipment to ensure they meet each one of our rigorous standards.

Options and Accessories

  • Priming System: An electric, oil-free rotary vane primer mounted directly on a Waterous split-shaft pump transmission or separately mounted combined with a Waterous priming valve forms the priming system. A lubrication option allows the use of Prime-Safe lubricant (priming tank is required when the lubrication option is selected).
  • Pressure Governor: Operates in PRESSURE or RPM; maintaining steady pump discharge pressure controlling the engine speed or by holding a selected engine RPM. Discharge pressure or engine RPM do not vary when switching between modes. Automatic low hydrant alarm (<20 psi) is armed when connected to a pressurized water source. Two-year warranty.
  • Pressure Control System: The Waterous Intake Relief Valve system is designed to act as a safety valve by "dumping" excess pressure from the inlet side of the pump. The Discharge Relief Valve provides sensitive pump control to protect firefighters from sudden pressure surges resulting from changes in discharge flows from the pump.
  • Manifold Drain Valve Drains all points of the pump simultaneously with the operation of a single control.
  • Corrosion Protection: Replaceable magnesium element that is installed directly on the pump intake piping and into the pump waterway. These anodes sacrifice the magnesium element to galvanic corrosion.
  • Discharge Valves: Waterous ball-type discharge valves available in 2.5" and 3.5".
  • Overheat Protection Manager: The OPM consists of an illuminated warning light on the operator's panel whenever the pump approaches an overheat condition. Optional audible alarm is available.
