The Hypro 1502N-R Roller Pump is a reverse rotation pump constructed of a Ni-resist body, 6 Super Rollers and Buna seals. Reverse rotation means the shaft rotates clockwise. The Ni-Resist body of the 1502N-R is more chemically-resistant than similar cast iron bodies against the effects of pesticides, herbicides, liquid fertilizers, and other hard to handle fluids.
