  The PWS Electric Diaphragm Pump is a sealless, reciprocating pump driven by an electric motor, designed to handle high-viscosity, abrasive, or hazardous fluids (e.g., 98% sulfuric acid, honey, sewage sludge) through diaphragm pulsation. Unlike centrifugal pumps, its electric double diaphragm pump mechanism enables bidirectional suction/discharge, achieving 3-meter self-priming with zero risk of leakage – critical for chemical transfer or food-grade applications requiring hygienic standards.
 

Structural Advantages of the Electric Double Diaphragm Pump


  • Transporting  Various Media

It can transport all kinds of highly toxic, flammable, volatile liquids, strong acids, strong alkalis, highly corrosive liquids, and high temperature media. It can also transport liquids with particles, and particles and mud with a diameter of less than 10 mm can pass effortlessly.

  • Good Sealing

Since the diaphragm separates the transported medium and the transmission mechanical parts, the medium will not leak out; and the electric diaphragm pump itself has no shaft seal, which greatly extends its service life.

  • Optional Diaphragm Material

According to different media, the diaphragm can be divided into chloroprene rubber, fluororubber, nitrile rubber, polytetrafluoroethylene, Teflon (F46), etc., which can meet the requirements of different customers.


 

How the Electric Diaphragm Water Pump Works


  • Motor Drive

The geared motor converts rotational energy into linear motion via a crankshaft and reversing linkage.

  • Diaphragm Actuation

Diaphragms reciprocate, creating vacuum/pressure cycles in the pump chamber.

  • Valve Control

Four ball check valves alternate opening/closing, enabling bidirectional flow for scenarios like tanker bilge clearing or firefighting water transfer.

  • Dry-Run Protection

Automatically shuts down if fluid supply is interrupted, preventing diaphragm damage.


 

Key Applications of the Electric Diaphragm Pump


  • Chemical Industry

Can be used to transport corrosive media to the reactor, such as strong acid, strong alkali, organic solvent, corrosive liquid, etc.

  • Pharmaceutical Industry

Used to transport pharmaceutical raw materials to the production line, such as liquid medicine, injection, disinfectant, etc.

  • Environmental Protection

Used for the transportation and treatment of sewage and waste gas, such as sludge, wastewater, and waste liquid transportation, it is expanding its market share in environmental protection, wastewater treatment, construction, sewage, and fine chemicals.
