Product Description

The Hypro 4001N Roller Pump is a low flow, low pressure 4-roller pump capable of reaching a maximum flow rate of 9.1 gpm and maximum intermittent pressure of 150 psi.

This Hypro 4001 Series Roller Pump is great to use as a sprayer pump for a variety of agricultural and industrial spraying jobs. It also can be used for the fluid transfer of a range of liquids.

Ni-Resist housing materials featured on the Hypro 4001N, along with Viton shaft seals and Super Rollers, provide excellent chemical resistance and premium wear life when handling many general agricultural chemicals; for example, herbicides, pesticides, insecticides, emulsions, abrasives, some brush control chemicals, and more.

Hypro roller pumps feature an economical rotary-action roller principle where no check valves are required, while still providing positive displacement characteristics with less friction and lower starting torque than other pumps.

Pump shaft rotation on these Hypro 4001 Series Roller Pumps is clockwise for easy coupling to a gas engine.

Note: Use a pressure relief valve on the discharge side to prevent damage from buildup of pressure if pump discharge is blocked or closed and power source is still running.
