How do Diaphragm Pumps Work?
Diaphragm pumps are a type of positive displacement pump that use a rubber or plastic diaphragm and corresponding valves on each side of the pump head to pump fluid. When the diaphragm flexes, the pressure inside the pump lowers, drawing fluid into the suction side of the pump head. When the diaphragm flexes back, the fluid is forced out of the discharge side of the pump head. Many diaphragm pumps include check valves to keep the liquid from flowing backward in the pump.
Advantages of a Diaphragm Metering Pump
-
Low cost of ownership
A properly sized diaphragm metering pump requires very little maintenance, saving you time and money
-
Energy efficient
On the forward (power) stroke of a diaphragm pump, more motor torque is used, but much less on the reverse stroke
-
High pressure capabilities
Overcoming line pressure is easier with properly sized diaphragm metering pumps
-
Exclusive longer lasting diaphragm
The revolutionary DiaFlex® Diaphragms from Blue-White last the entire life of the pump
Applications
- Wastewater Treatment
- Potable Water Treatment
- Agriculture and Irrigation
- Car Wash
- Cooling Tower Water Treatment
- Boiler Feedwater Treatment
- General Chemical Metering

Diaphragm Pumps FAQ
Diaphragm pumps are a type of positive displacement pump that combines the reciprocating action of a diaphragm and valves on either side of a pump head to transfer fluid.
Pulsation dampeners are often used to reduce pressure fluctuation found in regular diaphragm pump operation. Another method is utilizing diaphragm pumps with two or more diaphragms that operate in succession. Blue-White’s multi-diaphragm pump, for example, features two diaphragm pump heads on either side of a drive enclosure. When one diaphragm is in the suction phase and the other in the discharge phase. The two diaphragms working together combined with a fluid manifold creates a smooth chemical feed profile that significantly reduces pulsation.
Diaphragm pumps are used in a variety of applications, including water treatment and conditioning, soap, wax and detergent injection, wastewater treatment, biocide feed, rural water systems, cooling tower & boiler water treatment, fertilizer and nutrient injection.
