Tri-Rotor Pump model 20CP, along with model 20D, is the smallest in the family of Tri-Rotor solid head pumps that provide constant flow rates.  This low cost pump is perfect for simple fluid transfer such as loading and unloading drums, totes, tanks, and trailers.  The pump serves a wide range of industrial markets and applications including oil, diesel fuel, and chemical transfer.

This close coupled double “C-flanged” mounted pump will provide years of trouble-free operation.  By properly bolting the motor feet, this unit requires no base plate and is self-aligning.

The pump is designed with side suction and top discharge threaded ports and is available in both clockwise (CW) and counterclockwise (CCW) rotations for pump installation flexibility.  Materials of construction for the 20CP model include Iron Fitted, All Iron, Bronze Fitted, or All Bronze configurations.
