Electric Diaphragm Pump with No Shaft Seal for Petrochemical Industries

1. Since the diaphragm isolates the conveyed medium from the transmission mechanical components, no medium leakage to the external environment occurs;

2. The electric diaphragm pump itself is equipped with no shaft seal, which significantly extends its service life;

3. It is capable of pumping both flowing liquids and non-easy-flowing media, and integrates multiple advantages of conveying machinery such as self-priming pumps and impurity pumps;

4. User-friendly operation with no need for priming water; reliable performance is achieved simply by powering on the unit;

5. Boasts a simple structure with few wearing parts, facilitating easy installation and maintenance. The conveyed medium does not come into contact with moving parts like the pump’s connecting rods and bearings, reducing component wear and performance degradation;

6. Suitable for transporting viscous liquids (below 10000 centipoise);

7. Features a spacious flow path with excellent passage performance, allowing a maximum particle diameter of 3.2mm to pass through, resulting in minimal pump wear when handling impurity-laden liquids;

8. Operating environment temperature range: 5-65°C; conveyed medium temperature range: -20°C-150°C;

9. The wetted parts of the pump body can be customized as cast steel, stainless steel, aluminum alloy, fluoroplastic, etc., based on different user requirements; diaphragms can be selected as neoprene, fluororubber, nitrile rubber, PTFE, Teflon, etc., according to the medium type;

10. Diaphragm pump motors are available in standard motors, explosion-proof motors, variable frequency motors, and variable frequency speed control motors.
