HOW A DIAPHRAGM PUMP WORKS

The pump is driven by an AC or DC motor

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.

The volume of flow is determined by several factors including the number and size of the pump chambers, cam offset, operating pressure, fluid viscosity

FUNCTIONS OF DIAPHRAGM WATER PUMP

• High flow rate and low-pressure requirements.
• Automatic electric water pump, working rate 1.8-2.5meters, max flow rate more than 5 meters.
• Water purification, filter machine, chemical metering, and fluid supply.
• Food, Beverage filling, and transfer.
• Controlled by the pressure switch.
