Advantages and Applications of Diaphragm Pumps for Acid and Alkali Transfer

 Advantages and Applications of Diaphragm Pumps for Acid and Alkali Transfer

In industries such as chemicals, pharmaceuticals, and electroplating, the safe transfer of acid and alkali liquids is crucial. These fluids are highly corrosive, which places strict demands on pump materials and sealing performance. The diaphragm pump has become the ideal solution for acid and alkali transfer thanks to its unique working principle and excellent corrosion resistance.

1. Working Principle of Diaphragm Pumps

Diaphragm pumps operate by the reciprocating movement of a flexible diaphragm, which changes the pump chamber volume and enables suction and discharge. Since the fluid only comes into contact with the diaphragm and valve body, there is no risk of leakage from traditional seals. This makes diaphragm pumps highly suitable for handling corrosive acid and alkali solutions.

2. Advantages of Using Diaphragm Pumps for Acid and Alkali Transfer

Strong Corrosion Resistance: Materials such as PTFE and stainless steel provide excellent protection against strong acids and bases.

Leak-Free Design: The diaphragm structure eliminates leakage risks caused by mechanical seal failures.

Versatile Applications: Suitable for both continuous and intermittent operations.

Low Maintenance Costs: Simple structure with fewer wearing parts makes maintenance easier.

3. Application Scenarios

Chemical Industry: Transfer of sulfuric acid, hydrochloric acid, sodium hydroxide, and other corrosive liquids.

Electroplating Industry: Circulation of acid and alkali washing solutions.

Pharmaceutical Industry: Precise dosing of corrosive solvents.

Environmental Protection: Collection and treatment of acidic and alkaline wastewater.
