Determination of pump model

Determination of pump model

After the type, series and material of the pump are selected, the model (that is, the specification) of the pump can be determined according to the sample and relevant information provided by the company.

Determination of centrifugal pump type

Determination of rated flow and head

The rated flow is generally directly used the maximum flow, such as the lack of maximum flow value, usually take 1.1 to 1.15 times of the normal flow.The rated lift is generally 1.05 ~ 1.1 times the lift required by the device.

For media with viscosity > 20mm2/s or containing solid particles, it is necessary to convert the rated flow rate and head when transporting water, and then perform the following work.

Choose the pump model with the highest comprehensive index as the final selection.Specifically, the following parameters can be compared: efficiency (high pump efficiency is best), weight (light pump weight is best) and price (low pump price is best).
