Common centrifugal pump names and specifications

1. Single-stage centrifugal pump
Single-stage centrifugal pump is the simplest centrifugal pump, with only one impeller and one inlet, which is widely used in municipal water supply and drainage, agricultural irrigation, industrial water supply and other fields. The main parameters include flow, head, speed, power and efficiency, etc. Common specifications are:
1. QW submersible sewage single-stage centrifugal pump: flow range 1-5000m3/h, head range 1-50m, suitable for sewage and household sewage discharge without solid particles or fibers and other suspended solids.
2. IS single-stage single-suction centrifugal pump: flow range of 1.5-1200m3/h, head range of 5-125m, suitable for treating water and liquids with physical and chemical properties similar to water, and the conveying temperature does not exceed 80°C.
3. TSWA agricultural centrifugal pump: flow range 3.2-150m3/h, head range 5-125m, suitable for rural irrigation, garden sprinkler irrigation, etc.
2. Multistage centrifugal pump
Multistage centrifugal pump is a centrifugal pump with multiple impellers connected in parallel or in series, its head is higher than that of single-stage centrifugal pump, and is widely used in high-rise buildings, industrial circulating water, water conservancy and hydropower and other fields. The main parameters include flow, head, power, efficiency, suction inlet diameter and discharge outlet diameter, etc. Common specifications are:
1. D-type multistage centrifugal pump: flow range of 5-150m3/h, head range of 24-240m, suitable for conveying hot water, cold water and liquids with physical and chemical properties similar to water with liquid temperature not exceeding 80°C.
2. CDL stainless steel multistage centrifugal pump: flow range 0.4-240m3/h, head range 24-240m, suitable for conveying clean media without solid particles and chemical and physical properties similar to water.
3. WFB non-leakage magnetic drive multistage centrifugal pump: flow range 1.5-100m3/h, head range 20-100m, suitable for conveying flammable, explosive, toxic and harmful and other dangerous media.
3. Self-priming centrifugal pump
Self-priming centrifugal pump is a kind of centrifugal pump that produces negative pressure for liquid through centrifugal action, so as to achieve self-priming, which has the characteristics of strong self-priming ability and convenient operation, and is widely used in municipal water supply and drainage, industrial circulation, sewage treatment and other fields. The main parameters include flow, head, suction lift and power. Common specifications are:
1. CYZ-A self-priming centrifugal pump: flow range 3.2-600m3/h, head range 12-80m, suitable for conveying water or liquids with physical and chemical properties similar to water.
2. JET self-priming centrifugal pump: flow range of 3-20m3/h, head range of 30-100m, suitable for conveying clean water or liquid with chemical and physical properties similar to water with a temperature of no more than 80°C.
3. ZX self-priming centrifugal pump: flow range of 3.2-600m3/h, head range of 12-80m, suitable for transporting water or liquids with physical and chemical properties similar to water, and containing a small amount of suspended solids and fibers and other fine particles.
In general, centrifugal pump is an indispensable equipment in the fields of industrial and agricultural production, municipal water supply and drainage, and construction, and choosing the right centrifugal pump specification can improve production efficiency and save energy consumption.
