Diaphragm Pumps
Diaphragm pumps use a combination of reciprocating action of a rubber, thermoplastic, or Teflon diaphragm and suitable valves on either side of the diaphragm to pump a fluid.
Components of Diaphragm Pumps
- Diaphragm: The flexible membrane that creates variable volume in the pump chamber.
- Inlet and Outlet Valves: Control the flow of fluid into and out of the pump chamber.
- Pump Chamber: The area where the fluid is drawn in and displaced by the diaphragm’s movement.
Types of Diaphragm Pumps
- Air-Operated Diaphragm Pumps: Driven by compressed air, ideal for aggressive chemicals.
- Mechanical Diaphragm Pumps: Mechanically driven diaphragm, often used in water treatment.
Applications of Diaphragm Pumps
- Chemical processing
- Pharmaceuticals
- Water treatment
- Food and beverage
Advantages of Diaphragm Pumps
- Can handle aggressive chemicals
- Suitable for hazardous areas
- Self-priming
