Chemical pumps are essential components in many industrial processes that handle hazardous, corrosive, and high-temperature chemicals. These pumps are designed to handle aggressive chemicals and slurries, and their operation is critical to the safety, efficiency, and productivity of chemical processes.

They play a vital role in ensuring the safe and efficient handling of these chemicals, minimizing the risk of accidents, improving productivity, and reducing downtime.

In this article, we will examine four things you need to know about Pumpbiz chemical pumps:

Types of Chemical Pumps:

There are several types of chemical pumps, including centrifugal, positive displacement, and diaphragm pumps:

Centrifugal Pumps:

Centrifugal pumps create a flow of fluid through an impeller, which rotates and forms a centrifugal force that draws fluid into the pump and pushes it out through a discharge outlet. Centrifugal pumps are commonly used in applications where high flow rates are required, such as in cooling systems, water supply systems, and irrigation systems.

Positive Displacement Pumps:

Positive displacement pumps work by trapping a volume of fluid and then pushing it out of the pump through a discharge outlet. These pumps have a fixed displacement, meaning they move a fixed volume of fluid per cycle, regardless of the pressure. This makes positive displacement pumps suitable for applications requiring precise flow rates, such as chemical dosing systems or applications requiring high pressure. Positive displacement pumps come in several types, including piston pumps, gear pumps, and screw pumps.

Diaphragm Pumps:

Diaphragm pumps use a flexible diaphragm to move fluid in and out of the pump. The diaphragm is typically made of rubber or plastic and is mounted on a piston that moves back and forth, drawing fluid into the pump and then pushing it out through a discharge outlet. Diaphragm pumps are often used in applications where a high degree of precision is required, such as in medical or laboratory settings, where accuracy and control are critical.

Material of Construction

Chemical pumps are typically made from materials that can withstand the corrosive and abrasive properties of the substances they handle. Common materials used in chemical pumps include stainless steel, plastic, ceramic, and exotic alloys such as Hastelloy or Inconel. The choice of material will depend on the specific chemical being handled, as well as the pump’s operating conditions, such as temperature and pressure.

Seal and Gasket Selection

Seal and gasket selection is critical in chemical pump applications to prevent leaks and ensure safe operation. The type of seal or gasket required will depend on the chemical being handled and the pump’s operating conditions. Standard sealing options include mechanical seals, packing, and gaskets.


Regular maintenance is crucial for the safe and efficient operation of chemical pumps. Maintenance activities may include lubrication, replacement of seals and gaskets, an inspection of impellers and other components, and monitoring performance metrics such as flow rate, pressure, and temperature. In addition, it is essential to follow proper operating procedures and to train personnel on the safe handling of chemicals and the operation of the pump.


By understanding these critical aspects of chemical pumps, businesses can ensure that their equipment is reliable, safe, and efficient.
