CRU-2 High Flow Series Pump
CRU-2 High Flow Series Pump
Waterous CRU-2 single-stage centrifugal high-flow pump mated to C21 or QC chain-driven transmission or driven by a TC21 split-shaft PTO can be utilized in municipal firefighting, aircraft firefighting, dewatering or for industrial applications. CRU-2 has a flow through rate of 6800 GPM (25000 l/min).

C21 /QC/ TC21 Transmission / PTO 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.
