What is a Chemical Pump?

Posted on 14 February 2015
A chemical pump is necessary when the liquid you are moving cannot be used with a regular style pump. They are often used when a chemical that needs to be transferred is either corrosive or abrasive. Some of the industrial liquids commonly used with chemical pumps include: sulphuric acids, acetic acid and sodium hypochlorite

They are far more durable than conventional pumps. Offering you the option of moving fluids in a variety of ways. You will find that a pump usually comes in two different types; a centrifugal pump or positive displacement pump, which one you use will depend on your specific application.

When purchasing one of these devices, it is important to make sure you get the right pump that it suited to the type of chemical you plan to transfer. Many centrifugal pumps come in the form of an ANSI process pump, depending on your specific application. Whereas positive displacement pumps are commonly known as screw pumps, diaphragm pumps or plunger pumps.

Chemical pumps are powered by a number of different sources. Depending on the device you are looking to get, it could be powered by one of these many sources: AC or DC voltage, hydraulic or pneumatic systems, gasoline or diesel engines, steam, water, and natural gas.

Types of Chemical Pumps

Magnetic Drive Pumps

This style of pump is great for transferring or moving corrosive and aggressive chemicals. It operates by using centrifugal forces to generate velocity. Allowing you to move an hazardous chemicals without the fear of leaks or spills.

Drum Pumps

A drum pump allows you to transfer chemicals from a 200 litre (44 gallon) drum. Making it easy move chemicals and acids from an extremely awarded barrel drum.

Air Operated Diaphragms Pumps

These chemical pumps come in a range of sizes and specifications, therefore it is important to pick one that is suited to your needs. A diaphragm pump also includes a discharge check valve to help prevent backflow.

Centrifugal Pumps

The velocity generated by the centrifugal forces make this pump highly effective at transfers extremely corrosive and hazardous chemicals. By utilising rotating impellers, they can increase velocity, and help to push fluids through an outlet valve.

Lobe Pumps

This positive displacement style pump is prefect for moving thicker products such as creams and oils.
