Acid Pumps

Acid pumps are pumps specifically designed to transfer, circulate, dose, or handle acidic and corrosive acids safely and reliably.

Unlike standard metal pumps, acid pumps are usually made with corrosion-resistant materials such as PP (Polypropylene), PVDF, PTFE, or SS 316 other chemically resistant materials, depending on the acid and operating conditions.

Common applications

Acid pumps are used for:

*  Sulfuric acid (H₂SO₄)

*  Hydrochloric acid (HCl)

*  Nitric acid (HNO₃)

*  Phosphoric acid

*  Acetic acid

* Chemical dosing and transfer

* Pickling and metal treatment

* Electroplating

* Water and wastewater treatment

* Chemical processing

* Pharmaceutical and industrial plants

Types of acid pumps

1. Magnetic Drive Pumps – Sealless design, reducing leakage risk; commonly used for corrosive chemicals.
2. Centrifugal Pumps – Suitable for continuous transfer and circulation.
3. Diaphragm Pumps – Often used for chemical dosing and applications requiring good chemical resistance.
4. Vertical Pumps – Useful for transferring chemicals from tanks and sumps.

Why material selection matters

The correct pump depends on acid concentration, temperature, flow rate, pressure/head, and chemical compatibility. For example, **PVDF** is often selected for demanding corrosive chemical applications, while PP is suitable for many less demanding chemical services.

For your pump business, a simple definition could be:

“Acid Pumps are specially engineered chemical pumps designed for the safe and efficient handling of corrosive acids and aggressive chemicals. Available in PP, PVDF and other corrosion-resistant materials, they provide reliable, leak-resistant performance for chemical transfer, circulation and dosing applications.
