Specifications
How a Diaphragm Pump Works:
1. The pump is driven by an AC or DC motor
2. In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outlet
3. The volume of flow is determined by several factors including: the number and size of the pump chambers, cam offset, operating pressure, fluid viscosity
Application:
1. Yacht / RV/Caravan pressurized water system
2. Sprayer fixtures (Vehicle-mounted sprayers, electric sprayer)
3. Clean machine, Humidifier, Water purification, Medical apparatus
4. Food beverage filling & liquid transfer
5. Any other pressurization system
