KDP Mechanical Diaphragm Pumps See all Brands

kdp pumps

KDP are a range of mechanical diaphragm pumps, manufactured, sold and supported by All Pumps. They incorporate a heavy duty gearbox coupled to an eccentric block to actuate the diaphragm, making them appropriate for heavy-duty applications.

The pump is belt-driven by pulleys which enables it to use a variety of drive options, including electric motors and petrol and diesel engines for 2” and 3” pumps. With the ability to self-prime, handle solids and run dry, they have a wide range of applications.

Application

All Pumps have been installed, servicing and supporting KDP pumps throughout Australia for many years.
