Plunger pumps, progressive cavity pumps, and roller spray pumps are high-pressure pumps for heavy-duty commercial uses. Plunger pumps are high-pressure pumps for car washes, pressure washers, and sewer jetting processes. Progressive cavity pumps distribute metered amounts of liquid in transfer processes. Roller spray pumps have parts that don't swell when exposed to chemicals or heat. They can transfer chemicals like liquid fertilizer, insecticide, and herbicide in agricultural spraying.
