In Addition To The Following Cases, Centrifugal Pumps Should Be Used As Much As Possible

Edit:Jiangsu KNL Hydraulic Pump IncUpDate:Jun 21, 2018

In addition to the following cases, centrifugal pumps should be used as far as possible:

a. When there is measurement requirement, choose the metering pump.

b. High requirements for head flow, small flow rate, and no suitable small flow High-lift centrifugal pumps are available. Reciprocating pumps can be used. If cavitation requirements are not high, vortex pumps can also be used.

c. When the lift is very low and the flow rate is large, axial and mixed flow pumps can be used.

d. When the viscosity of the medium is large (greater than 650~1000mm2/s), consider using a rotary pump or a reciprocating pump (gear pump, screw pump).

e. The vortex pump can be used when the medium gas content is 75%, the flow is small and the viscosity is less than 37.4mm2/s.

f. For occasions with frequent startup or inconvenient pumping, pumps with self-priming properties should be used, such as self-priming centrifugal pumps, self-priming vortex pumps, and pneumatic (electric) diaphragm pumps.
