CMD / CMUD

The low profile midship two-stage series/parallel pump with ball-type transfer valve allows you to switch from pressure to volume smoothly & easily.


When used with a TC20 Series Power Take-Off (PTO), the CM / CMUD can be rear-mounted in an apparatus.

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 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.
  • H-Manifold Discharge Fitting: Allows for efficient and easy installation of a Waterous pump and significantly improves manufacturing process throughput. Flexible design enables OEM's to easily adapt to customers' needs with a wide range of discharge openings. The H-manifold discharge arrangement creates panel dimensions that accommodate remote locking and quarter-turn valves.
  • Corrosion Protection: Replaceable zinc element that is installed directly on the pump intake piping and into the pump waterway. These anodes sacrifice the zinc element to galvanic corrosion.
  • Discharge Valves: Your choice of the trusted Waterous 1⁄4 turn 2.5 inch and 3.5 inch rack and sector push-pull, worm gear and electric discharge valves. All come standard with chrome-plated brass ball and hydraulically balanced seal assembly.
  • 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.
  • Foam Manager: Consisting of a 500 or 1000 GPM foam manifold and foam proportioner.
  • Power Shift: Pneumatic shift allows operator to shift from ROAD to PUMP position by actuating a valve.
  • Tank to Pump Valve: A full-flow 3.5-inch diameter ball valve, which is attached directly to the pump.
  • Tachometer: Tachometer drive standard and operates at 1/2 input shaft speed.
  • Electric Transfer Valve Actuator: An electric transfer valve provides smooth transfer to either PRESSURE or VOLUME.
  • 5-Year Limited Warranty with Total Protection Package (TPP-5): The Total Protection Package is a comprehensive warranty that increases your standard warranty to include labor expenses to dismantle, remove and reinstall covered products or parts.
