The fluoroplastic alloy chemical centrifugal pump is specially designed and developed for conveying corrosive media containing fine particles. The pump is made of steel-lined ultra-high molecular weight polyethylene (UHMW-PE). The most outstanding advantage of grinding engineering plastics is that it has the best wear resistance, impact resistance (especially low temperature impact resistance), creep resistance (environmental stress cracking resistance) and excellent resistance among all plastics. Corrosive.

1. Fluoroplastic alloy chemical centrifugal pump has a wide range of applications: a variety of interchangeable lining materials are available, which are suitable for the transportation of corrosive and abrasive clear liquids and slurries of various chemical properties, and spare parts of various materials are interchangeable. Good performance, user adjustment is extremely convenient.

2. The liquid inlet of the pump is in the same direction as the shaft seal, and the shaft seal is in a negative pressure environment, so it will not leak, which overcomes the problems that the original corrosion-resistant and wear-resistant pump is easy to be damaged and the shaft seal is easy to leak.

3. Low operating cost: There are two main factors. First, the wearing parts, pump cover and suction port, etc. adopt a split structure, with independent corrosion-resistant and wear-resistant wearing parts, which are easy to replace and more economical; second The seal of the pump does not use the back impeller to decompress, which saves the consumption of shaft power and energy.

4. The fluoroplastic alloy chemical centrifugal pump has good wear resistance, because with a lower linear velocity of a single impeller, a higher outlet pressure of the pump can be obtained, thereby overcoming the increase of the linear velocity of the impeller in order to increase the pressure of the single-stage slurry pump, which causes the impeller , The disadvantage of increased wear of the pump casing effectively improves the service life of wear parts such as impeller and pump cover.

The key to the installation technology of fluoroplastic alloy chemical centrifugal pump is to determine the installation height of the pump. This height refers to the vertical distance from the water surface of the water source to the center line of the impeller of the pump. It cannot be confused with the allowable vacuum suction height. The allowable suction suction height marked on the pump nameplate or product manual refers to the vacuum value on the water inlet section of the pump, and It is measured under the condition of 1 standard atmospheric pressure and water temperature of 20 degrees Celsius.
