Sprayer and washer pumps clean surfaces of dirt or apply herbicides over crops in agricultural applications. Electric sprayer pumps operate more efficiently than air-operated pumps. Air-operated sprayer pumps are driven by compressed air. Roller spray pumps use a series of rotating rollers to draw in, trap, and push liquids through the pump and out through the discharge port. Pressure washer pumps reach higher pressures than sprayer pumps to clean debris, build-up, and dirt from various surfaces such as concrete, wooden decks, and sidings. Repair kits for electric sprayer pumps and roller spray pumps replace commonly worn parts and keep equipment in good working order.
