1. Operating principle of acid-resistant pump

The working principle of an acid-resistant pump is similar to that of an ordinary pump, primarily relying on mechanical energy to transport liquid from a low-pressure area to a high-pressure area. Specifically, the acid-resistant pump generates centrifugal force through the rotation of the impeller, imparting kinetic and potential energy to the liquid, thereby achieving transportation. Due to the particularity of acidic media, special attention needs to be paid to the following points in the design and material selection of acid-resistant pumps:

Corrosion-resistant materials: The pump body and impeller are typically made of corrosion-resistant materials such as stainless steel, fluoroplastics, polypropylene, etc.

Sealing performance: The sealing system of an acid-resistant pump needs to possess good corrosion resistance and sealing ability to prevent leakage of acidic media.

Structural design: The structural design of the pump should minimize the contact area with acidic media to reduce the risk of corrosion.

II. Main types of acid-resistant pumps

Based on different working principles and structural characteristics, acid-resistant pumps are mainly divided into the following categories:

Centrifugal pump: It generates centrifugal force through the rotation of the impeller, transporting liquid from the inlet to the outlet. Centrifugal pumps feature high flow rates and high head, making them suitable for transporting large amounts of acidic media.

Magnetic pump: It utilizes magnetic force to drive the impeller to rotate, eliminating the need for mechanical seals and offering advantages such as leak-free performance and corrosion resistance. It is suitable for conveying highly corrosive and toxic acidic media.

Diaphragm pump: It delivers liquid through the reciprocating motion of the diaphragm, featuring strong self-priming ability and good corrosion resistance. It is suitable for conveying acidic media containing solid particles.

Screw pump: It conveys liquid through the rotation of the screw, featuring stable flow and high pressure. It is suitable for conveying acidic media with high viscosity and solid particles.
