How to deal with multi-stage pumps after a long period of time without turning? Consider improper storage leading to internal bearing jamming, or internal water is not drained in time to lead to impeller corrosion stuck, the corresponding treatment is also very simple, you can disassemble the impell Read More

Know in advance the multi-stage pump head and flow parameters can be better for the transport project to match the model, different manufacturers due to the choice of materials and production process differences, so the actual performance of certain differences, in the pump industry as a long-establ Read More

The use of multistage pumps is reflected in the high head water transport, the pump essentially belongs to the centrifugal pipeline pump, in the use of similar, suitable for industrial production and urban water system, commonly used for pressure transport, long-distance water transport, high-pressu Read More

Recently, some customers want to know the advantages and disadvantages of multistage pumps, so as to match the corresponding pump type for the transport conditions. In this regard, Zhaoquan Pump Industry introduces the superior points of multistage pumps in terms of their actual performance and appl Read More

1, the higher the working pressure of the multi-stage centrifugal pump, the greater the axial force of the pump rotor, the pump rotor will be to the low-pressure side of the faltering. Axial force if there is no balancing device to balance, acting directly on the high-speed rotation of the impeller, Read More

Vertical multistage pumps are vertical, single suction, multistage, sectional centrifugal pumps suitable for urban water supply and central heating systems. It is used to transport clear water or liquids with physical and chemical properties similar to clear water. The temperature of the pump convey Read More
