The Comet APS41P Diaphragm Pump is a high pressure, three diaphragm pump capable of handling pressures up to 580 psi (40 bar) and flow rates up to 11 gpm (41.6 lpm), making it very versatile in many spraying applications.
This internally manifolded high pressure diaphragm pump has plastic coated pump heads for excellent resistance to corrosion. The valve plugs and discharge plate are also plastic coated for additional protection in the most common corrosive areas. The plastic coating is an electrostatic dipped coating that penetrates the surface of the aluminum and cannot be easily chipped during transport.
The pump's 6 hole flange shaft permits multiple applications and can be adapted to PTO, gas engine, hydraulic motor, or belt drive applications. Perfect for use in the nursery, agricultural, and horticultural industries.
Use the Comet APS41P Diaphragm Pump to pump and spray a range of agricultural chemicals, including liquid fertilizers, herbicides, pesticides, insecticides, de-icing materials, and other hard-to-handle fluids. It is great for handling certain harsh chemicals used for disinfecting, roof moss control, mosquito control, and more with its special plastic coating.
A unique feature on this pump is its "Duraphragm" technology, which extends the diaphragm's life by protecting it from being in direct contact with the chemical inlet. This spreads inlet vacuum, sometimes caused by a dirty suction filter or kinked hose, across the entire diaphragm surface rather than focusing it on one small area where most failures occur.
APS41P: Three diaphragm pump with universal drive face and mounting rails.
APS41P-GR: Three diaphragm pump with gear reduction for gas engines with 3/4" shafts. Includes pressure regulator with manual dump lever.
Note: If you have an existing APS41P-GR and you need to replace the pump, the gearbox can be reused and all you need to order is the plain APS41P Pump.
