ZA Chemical Process Pump
Product Description
This series of chemical process pump is an updated replacement. It is based on the American National Standards Institute’s ANSIB731M standard and combined with advanced pump manufacturing experience now. The super versatile and interchangeable design not only reduces spare parts storage and management costs but also reduces the overall operating cost of the pump, which makes it a new alternative across the general chemical industry by its unique durability, reliability, and economy.
No leakage is the eternal pursuit of chemical equipment.
1. For static seals, there are usually only two types of gaskets and seals, and O-rings are the most widely used seals. For dynamic seals, chemical pumps rarely use packing seals, mainly mechanical seals. Mechanical seals are divided into single and double end faces, balanced type and unbalanced type. The balanced type is suitable for high-pressure medium sealing (usually refers to a pressure greater than 1.0MPa). Double-end mechanical seals are mainly used for high temperature, easy to crystallize, and have viscosity. For media containing particles and toxic volatiles, double-end mechanical seals should inject isolation fluid into the sealed cavity. The pressure is generally higher than the medium pressure by 0.07 ~ 0.1MPa.
2. Sealing. The chemical process pump static sealing material generally uses fluoroelastomers. In special cases, PTFE is used. The material configuration of the dynamic and static ring of the mechanical seal is more critical. It is not that cemented carbide is the best. On the one hand, it is not reasonable for the two to have no hardness difference, so it is best to treat them differently according to the characteristics of the medium.
Product Features
Main Application
The seal cavity of the chemical process pump cover is designed as an inverted cone and is provided with a flow guiding block, which can reduce the pressure in the sealed chamber and keep the impurities in the medium away from the seal, so as to minimize the erosion of impurities on the seal.
The impeller adopts a back-open structure, and it is easy to adjust the gap between the impeller and pump cover.
Thin-oil is used to lubricate bearings. There are splashing discs to increase lubrication and cooling effect and constant oil cup to ensure sufficient lubrication.
The rotor is provided with an axial adjustment mechanism, which can allow adjusting the gap between the impeller and the pump cover from outside accurately without removing the pump, thereby it can achieve the purpose of adjusting the performance of the process pump and greatly simplify the maintenance process.
This series of chemical process pump is mainly used in chemical, petrochemical, refinery coal chemical, power plant, paper, pharmaceutical, sugar, steel, waste acid treatment, water supply, and drainage urban water supply, food deep processing and other industries.
