Acid Pumps

Acid pumps, also known as chemical or corrosive liquid pumps, are used for transferring acids and other corrosive fluids. They are commonly used in a variety of industrial applications that need the pumping of acidic liquids, such as chemical processing, mining, wastewater treatment, and laboratory settings.

 

Seeking a pump for Acid like Hydrochloric Acid (Muriatic Acid), Sulfuric Acid, Perchloric Acid, Phosphoric Acid, Nitric Acid, Acetic Acid Numatic Pumps are ausam. We have a total solution for Pumping any Chemicals and Viscosity. Our range of Pumps starts from 0.12 HP up to 50 HP and form 10 CPS up to 200000 CPS Viscosity.

 

Acid pumps are designed to be completely leak-proof and capable of handling the most toxic and corrosive chemicals such as acids, dyes, industrial solvents, fuels, and high-temperature liquids. They are Magnetic Drive Pumps which do not have expensive shaft seals, which make them economical and easy to maintain or replace. They are highly efficient thanks to the coupling which is achieved by high-power magnets, and completely eliminate the risk of hazardous substances leaking into the external environment.

We have all most all type and range of Pumps, Our Pump Type Includes

  • Magnetic Drive Sealless Pumps
  • Centrifugal Monoblock Pumps
  • Centrifugal Coupled Pumps
  • Centrifugal Self-priming Pumps
  • Centrifugal Horizontal Pumps
  • Centrifugal Vertical Pumps
  • Dairy and Sanitary Pumps
  • Air Operated Double Diaphragm Pumps

What are 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

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.

What is the difference between PP and PVDF acid pumps?

Acid pumps are made of materials that are resistant to the corrosive nature of acids. Pump components are commonly constructed of polypropylene (PP), polyvinylidene fluoride (PVDF), or fluoropolymers such as PTFE (polytetrafluoroethylene). These materials give resistance to acid corrosive effects and assure the pump’s longevity and reliability.

Both PP and PVDF materials can provide chemical resistance, but their suitability varies by chemical and temperature. PVDF is often selected for more demanding chemical applications and sustains temperatures up to 100 degrees, while PP can be suitable for many general corrosive-fluid applications and can sustain temperatures up to 70 degrees Celsius.
