Description

When you’re looking at building a custom spray rig or replacing the pump on your existing unit, you need something that’ll handle chemicals without breaking down and keep pushing fluid day after day. This Hypro 4-roller cast iron pump is built for exactly that kind of work. It’s designed to mount directly to a gas engine and run reliably at higher speeds than most pumps can handle.

What You’re Getting

Cast iron construction that stands up to chemicals and weather year after year
Four super rollers that create smooth, consistent flow at 7.2 GPM
Viton seals that resist chemical breakdown and maintain their seal over time
5/8 inch solid shaft that couples directly to small gas engines without adapters
Can run at speeds up to 2600 RPM—higher than most roller pumps

Built for Real Farm Work

This pump is designed especially for agricultural and industrial spraying applications where you need reliable chemical transfer. Whether you’re mixing herbicide in a nurse tank, running a small field sprayer, or building a custom spray setup for fence lines and ditches, this pump delivers the pressure and flow you need. At 150 PSI max, it’s perfect for boom sprayers, hand guns, and other medium-pressure applications.

Made to Last

The cast iron housing resists corrosion from farm chemicals better than aluminum, and the Viton seals are specifically chosen because they won’t swell or deteriorate when exposed to most herbicides and pesticides. This pump runs at speeds up to 2600 RPM, which means you can get good flow rates from smaller engines—handy when weight and space are factors.

Good to Know

The clockwise rotation and 5/8 inch solid shaft make this pump a direct fit for many small gas engines. The 3/4 inch NPT ports give you flexibility in plumbing, and the compact size means it’ll fit in tight spaces. If you’re rebuilding or maintaining the pump, all the standard Hypro repair parts are readily available.
