Centrifugal pumps are classified according to the number of impellers, including single-stage pumps and multi-stage pumps; according to working pressure, there are low-pressure pumps, medium-pressure pumps, and high-pressure pumps; according to the position of the pump shaft, there are horizontal pumps and vertical pumps; According to the purpose, it can be divided into oil pump, water pump, condensate pump, ash discharge pump, circulating water pump, etc. Today we will introduce several common centrifugal pumps according to their use.

UHB-ZK Chemical Centrifugal Pump is the most widely used in chemical production. This is due to its wide range of performance, small size, simple structure, easy operation, uniform flow, less young and Dangerous, long life, purchase and operation costs Both are lower and have outstanding advantages.

There are 29 basic types of IS clean water centrifugal pumps. It has the characteristics of wide range of pumps, high level of "three modernizations", reliable structure, convenient maintenance, low vibration, low noise, and high efficiency. It is a popular energy-saving product. IS clean water centrifugal pump is a single-stage single-suction (axial suction) centrifugal pump. It is used to transport clean water without solid particles and with a temperature not exceeding 80 ℃ or other liquids with physical and chemical properties similar to clean water. The working pressure is ≤0.3MPa, suitable for Industrial and mining enterprises and urban water supply and drainage and agricultural irrigation and drainage.

The WZW series self-priming sewage pump is designed with a water storage chamber, and adopts a horizontal water injection horizontal bearing box structure, and the shaft seal adopts a skeleton seal or a mechanical seal. There is a water injection port on the top of the pump, which is convenient for operation. It has strong self-priming ability, no need to install bottom valve, no blockage, no entanglement, the large diameter of the soft solid block that can pass is 60% of the pump caliber, and the fiber length is 5 times the caliber. Impeller blockage by debris can be cleared in time. It is widely used in sewage transportation of factories and mines, treatment of various fiber wastes, large particle fixed blocks, sedimentation of waste mineral impurities, paper pulp, sewage, etc.

The hot oil pump has a reasonable structure, excellent performance and reliable use. It is suitable for conveying high temperature liquid without solid particles. The corresponding material can be selected according to the contact medium, which can achieve a higher degree of corrosion resistance and use temperature. It is widely used in petroleum and chemical industry, synthetic fiber industry, textile printing and dyeing industry, plastic and rubber industry, paper industry, etc.

The AY series single two-stage centrifugal oil pump is modified and redesigned on the basis of the old Y-type oil pump series. It is a new product developed to meet the needs of modernization and adapt to the new generation of energy-saving equipment as soon as possible. AY series single two-stage centrifugal oil pump is divided into single-stage single-suction and two-stage single-suction cantilever type, single-stage suction cantilever type, single-stage double-suction and two-stage double-suction and two-support type, two-stage single-suction and two-support type, etc. It can be used in petroleum refining, petrochemical and chemical industries and other places to transport petroleum, liquefied petroleum gas and other media without solid particles.
