Gear oil pumps for chemical and pharmaceutical use must consider many factors during selection, use and maintenance to ensure that they can meet actual process requirements and maintain good operating conditions.

Chemical pumps are made of a variety of materials, and the selection needs to be comprehensively considered based on factors such as the specific medium properties, process requirements, and environmental conditions.

Ceramic pumps play an important role in many industrial fields due to their high corrosion resistance, wear resistance, high temperature stability, low noise and vibration, and easy installation.

When selecting a pump for corrosive liquid transportation, it is necessary to comprehensively consider factors such as liquid properties, pump performance parameters, materials, sealing performance, maintenance and repair. Recommended pump types include shielded pumps, diaphragm metering pumps, magnetic drive pumps (including self-priming magnetic pumps), centrifugal corrosion-resistant pumps and long-axis vertical submersible pumps.

Stainless steel centrifugal pumps are widely used in many industrial fields due to their excellent corrosion resistance. However, different media have different corrosiveness, so how to optimize the material and surface treatment of stainless steel centrifugal pumps for specific corrosive media to extend their service life is a problem worthy of attention.
