How to Install a Wet End Kit on Diaphragm Pumps | Video

Sandpiper Pumps demonstrates how to disassemble an air end kit on a diaphragm pump and install a wet end kit on a diaphragm pump. This how-to video includes the necessary tools for dismantling a diaphragm pump, how to disassemble a diaphragm pump, how to clean and inspect the parts of a diaphragm pump, how to replace the parts on the wet end of a diaphragm pump, and how to reassemble the diaphragm pump.

Air-operated diaphragm pumps work by shifting air from one chamber to another, using two large diaphragms on either end of the machine. When one chamber is void of air, fluid rushes is, and when air rushes back into the diaphragm, the fluid is pressurized and expelled. A one way check valve ensures that fluid flows in the correct direction. This generates enough pressure for the diaphragm pump to be reliably used for cleaning or spraying applications.

The wet end kit includes diaphragms, check balls, and seats. For air end kit replacement, watch this video.

Sandpiper diaphragm pumps are suited for moderately abrasive fluids and suspended solids. Sandpiper diaphragm pumps are availiable with Poly, Kynar, Aluminium, or Stainless Steel bodies and Teflon, Santoprene, or Buna diaphragms.
