Required

2 piston semi-hydraulic diaphragm pumps, flow rate up to 27 l/min. (7,1 US GPM) and pressure rating up to 20 bar (290 P.S.I.).
They are an excellent choice for spraying and pest control applications in gardens, greenhouses, lawns; they are well suited for liquid transfer and for industrial use (distribution of water soluble detergents and paints). Ready to accept electric motors, gasoline engines, pulleys, shaftskits, quick attach chain kit/rigid bar kit. All wetted parts are either polypropylene (Poly 2020-2025 series) or anodized (Trial series) for protection against corrosion.
