What is a plastic centrifugal pump (plastic pump)?

Plastic centrifugal pumps are an essential part of a variety of industrial processes designed to handle fluids that can damage or corrode other types of pumps. They are made using industrial plastic components or casing materials, also known as engineering plastic pumps.

Plastic centrifugal pumps are particularly suitable for handling corrosive fluids. They are made of materials such as polypropylene and PVDF and can handle a wide range of fluids, including hydrochloric acid, sulfuric acid, nitric acid and many other chemicals.

In short, plastic centrifugal pumps are reliably, efficiently and safely used to handle corrosive fluids in industrial processes…

Benefits of Using Plastic centrifugal Pumps

Compared to metal pumps, plastic centrifugal pumps offer a wider range of chemical resistance and are less expensive and lighter. They are corrosion-resistant, wear-resistant, and have high-temperature resistance. Plastic pumps are also known for their advanced and reasonable structure, strict and reliable sealing performance, and long service life. They have high mechanical strength, run smoothly, and are easy to disassemble and maintain.

Applications of Plastic centrifugal Pumps

Plastic centrifugal pumps have a compact structure, beautiful appearance, small volume, low noise, reliable operation, and are easy to use and maintain. They are widely used in chemical, pharmaceutical, petroleum, electroplating, food, scientific research institutions, national defense industry, and other units for pumping acid, alkali liquid, oil rare and precious liquid, toxic liquid, and volatile liquid. They are particularly useful for pumping liquids that are easy to leak, flammable, or explosive, and are ideal for use with explosion-proof motors.

Selection of Materials for Plastic centrifugal Pumps

The selection of materials for plastic pumps is crucial. Common engineering plastics used to make plastic pumps include PVDF, ETFE, and PFA. These materials have excellent strength, impact resistance, high-temperature resistance, wear resistance, corrosion resistance, hardness, and aging resistance. They can meet the different industrial requirements of the product and are carefully selected to ensure the pump’s reliability and longevity.

If you need an efficient and reliable magnetic drive plastic pump, this is the one for you.


The pump is characterized by smooth flow, low noise, etc. It is made of PP/PVDF with strong corrosion resistance and tight and reliable sealing performance, and can be used for acid and alkali solution transfer/circulation. The pump is compact and economical, with long service life and very convenient maintenance.
QHG centrifugal pumps
QHD Vertical Pumps


Available in CFRPP, PVDF or polypropylene, this pump has strong corrosion resistance and is suitable for chemical transfer tasks involving corrosive liquids, caustic alkalis and bases. The pump features a plastic impeller without metal inserts, which resists acid attack even internally. The pump is a tailor-made vertical chemical pump, designed to meet the specific dimensions of each installation tank. With the motor mounted vertically above the liquid surface, the pump does not require any mechanical seals, which are usually the source of leakage problems.

Questions about Plastic centrifugal Pumps

What is a plastic centrifugal pump?

Plastic centrifugal pumps, also known as plastic pumps, are highly resistant to aggressive chemicals and acids due to their materials like polypropylene and PVDF. These pumps are often referred to as “Plastic (centrifugal) pumps” because of their plastic casing.

Can plastic pumps transport 40% hydrochloric acid?
