Electric Diaphragm Pump

Compared with air operated diaphragm pumps, the electric design does not require a compressed air supply, allowing direct connection to a power source for operation. This makes it especially suitable for fixed installation systems where compressed air equipment is unavailable or unnecessary.

Featuring a diaphragm isolation structure, the Electric Diaphragm Pump separates the pumped medium from the drive components, eliminating shaft seal leakage risks. It can handle corrosive liquids, particle-containing fluids, and high-viscosity media, making it widely used in chemical dosing, water treatment, coating systems, and industrial material transfer applications.

Stable Electric Drive Performance

Powered by an electric motor, the pump provides continuous and stable flow output without requiring an external compressed air system, making it suitable for long-term fixed installation applications.

Core Advantages

1. Leak-Free Diaphragm Isolation Design

The diaphragm structure prevents direct contact between the fluid and mechanical drive components, reducing leakage risks and improving operational reliability.

2. Variable Speed Control Available

With frequency conversion speed regulation, users can precisely adjust flow output according to different process requirements, improving system control and efficiency.

3. Corrosion & Chemical Resistance

Pump wetted parts are available in multiple materials including stainless steel, PP, PVDF, and fluorine-lined options to handle different chemical media.

4. Explosion-Proof Motor Option

The explosion-proof motor version is designed for hazardous environments such as petroleum, chemical processing, and coating industries.

5. Stable Flow Output for Fixed Installations

Unlike air-operated pumps, the electric design does not require a compressed air supply, allowing direct connection to a power source for operation. This makes it especially suitable for fixed installation systems.

Technical Specifications

Working Principle

The Electric Diaphragm Pump operates through an electric motor connected with a mechanical drive mechanism. The motor converts rotary motion into reciprocating movement through a crank linkage or eccentric structure, continuously moving the diaphragm back and forth.

During operation:

1. The diaphragm moves backward to create negative pressure and draw liquid into the chamber.
2. The diaphragm moves forward to compress the chamber and discharge the liquid.
3. The check valve system controls the fluid direction to achieve continuous pumping.

This working principle enables reliable transfer of various liquids while maintaining isolation between the medium and mechanical components.
