Water Diaphragm Pump

June 18, 2020

A diaphragm water pump is mainly composed of motor, transmission components, flexible diaphragm, check valves, and an accommodation

diaphragm, which is between the air nozzle and the chamber to absorb vibration when the fluid enters the pump body. It utilizes a flexible diaphragm that reciprocates back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. When the volume of a chamber of pump is increased, the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume, the fluid previously drawn in is forced out. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle.
