CRU-2 High Flow Series Pump

Waterous CRU2 pump was created with the Industrial market in mind. Rated at 4000 GPM @ 100 PSI (15000 l/min @ 6.9 bar) with flow through rates up to 6800 GPM (25000 l/min), makes the CRU2C21 the highest NFPA rated performance pump in the market. Available for midship mounting on all industrial-style fire trucks and direct mounting to diesel-powered units for skid-based systems or trailer units.

C21 Transmission Features

  • High-strength aluminum, three-piece, horizontally-split housing
  • Drive line shafts made from alloy steel forgings, hardened and ground to size, 2.35 inch 46-tooth involute spline.
  • Drive and driven sprockets are hardened and have ground bores.
  • Integral water cooler provision.
  • Morse HV® high-strength involute form drive chain.
  • Deep-groove, anti-friction ball bearings give support and proper alignment to the impeller shaft assembly. Bearings are oil-splash lubricated, completely separated from the water being pumped, and protected by a V-ring and oil seals.
  • An internal lubrication system delivers lubricant directly to the drive chain. This unique design eliminates the need for an external lubrication pump and auxiliary cooling.
  • Shift mechanism consists of a constant-mesh, two-position sliding collar that engages all teeth simultaneously. In-cab controlled pneumatic shift.  An internal locking mechanism provides a positive lock in PUMP or ROAD position.
