Top 10 Applications for Chemical Resistant Pumps

Harsh chemicals are key to operations in many industries. Whether they are part of the end product, or they are used in the process of creating the end products, the ubiquitous status of chemicals has made chemical resistant pumps crucial for a wide range of applications.


These pumps deliver the durability and reliability needed for requirements that involve harsh chemicals. Pump owners can rely on chemical resistant pumps for leak-free operation, low maintenance, and longevity. This robust design makes chemical resistant pumps ideal for the following applications.

1. Automotive

Automotive assemblers and their suppliers require systems that can produce precision components. In this industry, chemical resistant pumps play a vital role in the treatment of metal parts including chrome and nickel plating and finishing. They are also used for surface cleaning and preparation prior to painting. Throughout the process of developing and assembling a vehicle, chemical resistant pumps offer safe and reliable liquid transfers that make precision processes possible.

2. Chemical Manufacturing

The creation, transfer, and distribution of harsh chemicals requires specialized pumps that can stand up to harsh or caustic materials yet be safe for the operator and the environment with zero emissions. Plus, they need to be efficient to use. Common applications include chemical loading and unloading, circulation for blending tanks, and fluid transfers within a facility.

3. Circuit Boards and Electronics

In this industry, the slightest imperfections can be costly. Manufacturers need systems that will allow them to meet stringent standards. The reliability of chemical resistant pumps makes them ideal for these processes while eliminating microbubbles. Circuit board and electronics manufacturers can count on chemical resistant pumps in filter, etch and rinse applications.

4. DEF/AdBlue

Diesel exhaust fluid requires careful handling. From construction sites, to commercial fleets, to agricultural equipment, equipment OEMs and operators need the right pumps for this job. Chemical resistant pumps offer the ideal solution to improve safety and reduce costs for DEF applications. These applications include blending, dispensing systems, and container-to-container transfers.

5. Electroplating & Anodizing

This industry involves a variety of complex tasks that incorporate harsh chemicals. Electroplating processes include filtering of chemicals and circulating through eductors. Anodizing processes include circulating dyes and sealers. Both processes include acid surface preparation and transferring chemicals from drums to tanks. Chemical resistant pumps offer the durable construction necessary for these operations.

6. Fume Scrubbers

For these applications, pressure and flow are key. Chemical resistant pumps help prevent corrosion problems that can cause loss of pressure. They also provide the necessary pressure for components such as spray nozzles and venturis. Additionally, chemical resistant pumps can provide the compact footprint that is ideal for fume scrubber OEMs.

7. Mining

Mining processes can generate hazardous byproducts. Chemical resistant pumps allow mine operators to safely handle these substances and the chemicals used to treat them. These pumps are also ideal for supporting the extraction process, offering reliable and durable pumping for mining operations. Common applications include the unloading chemicals from tanker trucks and rail cars and the transfer of chemicals on-site.

8. Steel Processing

The steel processing industry involves a wide range of complex chemical processes. Each has unique precision and safety concerns. To transfer the required chemicals, manufacturers must choose the right equipment. Chemical resistant pumps are designed to withstand these types of environments and offer an idea solution for applications such as galvanizing, steel pickling, wire processes, and wastewater management.

9. Water Treatment

Chemical resistant pumps offer the efficiency and durability required for success in the water treatment industry. These pumps can be used to transfer raw or contaminated water from processes, rapidly empty batch treatment tanks, unload chemicals from tank trucks, transfer chemicals, and handle the harsh chemicals involved in treating water.

10. Aquafarming

This industry requires delicate care to preserve a healthy aquatic environment. Without the right chemical resistant pumps, aquatic life suffers. These pumps provide proper tank circulation and assist with maintaining appropriate water levels and chemical balance. Portable chemical resistant pumps are also key for sampling and testing water and to transfer chemicals to specific tanks for treatment.
