The pumping cylinders are separated from the piston chambers by a synthetic diaphragm. This keeps the spray solution from contacting and corroding the internal pumps components. Driven by PTO, electric or gas engine diaphragm pumps are used for a variety of agricultural, horticultural and pest control spraying applications. The hand pumps use with herbicides, insecticides, fungicides or fertilizer. For mounting on barrels or trucks or any place fluids need to be dispersed.
Roller pumps are the number on all-round choice by farmers throughout the world.
The rollers revolve inside the pump housing to force the spray solution through the outlet to the nozzle. Roller pumps have a low initial cost and are extremely versatile. Roller pumps are self-priming and easily adapt to PTO or gas engine drives. Piston pumps are not unlike an engine. On the down-stoke, the inlet valve opens., filling the chamber with solution.
