In chemical manufacturing, hydrochloric acid is used to produce chloralkali, PVC, plastics, dyes, pharmaceuticals and other products. In metallurgy, it is used for steel pickling, metal surface treatment and other applications. In the power industry, hydrochloric acid is utilized in battery manufacturing, water treatment and related processes. Within the pulp and paper industry, applications include paper production and wastewater treatment. In textiles, hydrochloric acid is employed in fiber processing, dyeing and other stages. Additionally, in the food industry, it finds use in food processing, cleaning and associated functions.

Why Choose Hydrochloric Acid Pumps

Significance of Hydrochloric Acid Pumps

Hydrochloric acid is an extremely corrosive acid. If proper preventative measures are not taken during fluid transfer, it can damage the pump.If the specific gravity exceeds 1.1, impeller trimming is absolutely necessary to prevent motor decoupling or overload.

The combined or individual use of hydrochloric acid at higher concentrations and temperatures may render some pumps unsuitable. Regardless of temperature or concentration levels, it is strongly advised to contact QEEHUA PUMP directly before ordering a pump, to review your specific application. Proper pump selection is crucial given the hazard level of this chemical.

Factors in Choosing Hydrochloric Acid Pumps

Hydrochloric acid should not be used with metal components. Sealing and chemical compatibility are the two most important factors to consider when handling hydrochloric acid. Chemical compatibility is often the common source of limitations.

Hydrochloric acid transfer pumps are specialized pumps. There should be no metal parts in contact with the medium or acid. Non-metallic pumps should be used to transport hydrochloric acid. Within just a few hours, any metal in contact with hydrochloric acid becomes contaminated. Hydrochloric acid is particularly corrosive to metals. Metals such as aluminum, cast iron and some stainless steels are unsuitable for hydrochloric acid as they will severely corrode the material.

Types of Pumps and Their Applications

There are a few types of pumps that can be used to transfer hydrochloric acid, including diaphragm pumps and magnetic drive pumps.

  • Diaphragm pumps are positive displacement pumps that use a flexible diaphragm to pump fluid. These pumps are typically used for low flow applications and offer a range of construction materials like plastics and stainless steel.
  • Magnetic drive pumps use a rotating impeller to move the fluid. These pumps are more commonly used for high flow applications. Non-metallic magnetic drive pumps are the best choice as they have excellent sealing capabilities.

Features and Materials of Hydrochloric Acid Pumps

Characteristics of Hydrochloric Acid Pumps

Hydrochloric acid pumps are specialized equipment with the following key features:

  • Corrosion resistance: The materials used for hydrochloric acid pumps must have excellent corrosion resistance in order to meet the corrosive requirements of hydrochloric acid. Commonly used materials for hydrochloric acid pumps include polypropylene, PVDF, and stainless steel.
  • Good sealing: Hydrochloric acid pumps must have reliable sealing to prevent leaks of hydrochloric acid. Common sealing methods for hydrochloric acid pumps include mechanical seals and magnetic drive seals.
  • High safety: Hydrochloric acid pump designs and manufacturing must comply with safety standards to prevent accidental incidents involving operators during use.

Main Materials for Hydrochloric Acid Pumps

There are a few primary material options for hydrochloric acid pumps:

  • Polypropylene: Polypropylene is an inexpensive and corrosion-resistant plastic suitable for low concentration hydrochloric acid transfer at ambient/room temperatures.
  • PVDF: PVDF is a high-performance plastic with exceptional corrosion resistance and heat tolerance, making it well-suited for medium concentration hydrochloric acid transfer and high-temperature applications.
  • Stainless Steel: Stainless steel possesses good corrosion resistance and heat resistance, allowing it to effectively handle high concentration and high-temperature hydrochloric acid transfer jobs.

Advantages of Hydrochloric Acid Pumps

Hydrochloric acid pumps provide the following benefits:

Safety:  Their reliable sealing prevents hydrochloric acid leaks, ensuring safety for operators.

Reliability: Corrosion-resistant materials allow the pumps to serve long-term even in harsh environments.

Efficiency: Flow rates and pressures can be tailored to specific needs, meeting the demands of various applications.

Advantages of Sealless Magnetic Drive Pumps

Magnetic drive pumps are sealless pumps, making them the best choice for pumping hydrochloric acid at ambient temperatures. PVDF magnetic drive pumps are suitable for temperatures above 80 degrees Celsius. Due to the sealless and non-metallic design of magnetic drive pumps, there is no alternative for hydrochloric acid applications. It is well known that hydrochloric acid has extremely strong corrosive properties, and any metal cannot withstand contact for more than a few hours.

When transporting corrosive liquids like hydrochloric acid, the corrosion resistance of magnetic drive pumps is especially critical. The wetted parts of magnetic drive pumps are typically manufactured using materials with excellent corrosion resistance properties, such as polypropylene and PVDF. These materials can effectively resist the corrosive effects of hydrochloric acid and ensure the long-term stable operation of the equipment.


Centrifugal pumps use suction to draw liquid into the impeller, which creates a vacuum.The anti-corrosion performance of the anti-corrosion centrifugal pump depends on the material of the pump body. The centrifugal pump of QEEHUA PUMP is made of acid and alkali resistant materials such as PP and PVDF, which has strong anti-corrosion ability.

Questions about Hydrochloric Acid Pumps

What are hydrochloric acid pumps used for?

Hydrochloric acid pumps are specifically designed for transporting hydrochloric acid. Due to the highly corrosive nature of hydrochloric acid, these pumps must be manufactured using corrosion-resistant materials and feature reliable sealing to prevent leaks.

Hydrochloric acid is very aggressive and can corrode standard pump materials. Hydrochloric acid pumps utilize corrosion-proof plastics like polypropylene (PP) and polyvinylidene fluoride (PVDF), as well as stainless steel, to withstand the acid. The sealing design also incorporates more robust options like guide seals and double mechanical seals for leak prevention.

In summary, hydrochloric acid pumps are engineered to safely and reliably convey hydrochloric acid and other strong acids through the use of specialized materials and construction that can tolerate hydrochloric acid’s corrosive effects. They serve a critical role in industries where hydrochloric acid is used or handled.

What factors should be considered when choosing a hydrochloric acid pump?

The following factors need to be considered when selecting a hydrochloric acid pump:

Concentration and temperature of hydrochloric acid: Higher concentrations and temperatures require greater corrosion resistance and heat tolerance from the pump.

Flow rate and pressure of hydrochloric acid: The pump’s flow rate and pressure capabilities should meet application requirements.

Cost of the pump: The cost of a hydrochloric acid pump can vary depending on material selection, design, and performance specifications.

Proper material selection and design are crucial since hydrochloric acid is very corrosive. Parameters like flow rate, operating pressures, and temperature ranges must be thoroughly reviewed. Pump costs may be higher but it’s essential to choose a product engineered to withstand the harsh acid environment. Considering all these selection criteria will help ensure operational safety and reliability.
