Source:How to choose the right pump | Updated: Jul 17, 2015

Single-stage vortex pump is available for direct suction water or physical and chemical properties similar to liquid water, the use of liquid temperature does not exceed 60, commonly used in boiler feed water facilities, shipbuilding, textile, chemical, metallurgy, machinery manufacturing, aquaculture, fixed fire regulators, heat exchangers group, agricultural remote sprinkler and other departments have a wide range of applications. Whirlpool pump commonly used in boiler feed water facilities, in shipbuilding, textile, chemical, metallurgy, machinery manufacturing, aquaculture, fixed fire regulators, heat exchangers group, remote sprinkler irrigation agriculture and other sectors and so have a wide range of applications.

According to the determined design flow and design head, in the type of spectrum, first on the ordinate in order to meet the head design head to find out the requirements and the flow ranging from several pumps, and then on the horizontal axis to determine the selection of the design flow rate Which pumps. If the design flow is large, single pump failed to meet the requirements, consider multi-machine operation, but should pay attention to try to use the same type of Shanghai water pump, in order to facilitate construction of the installation, management and maintenance.

1. Pump Performance Specification Election pump water pump factory in catalog provides such a table, the performance table of each model has three lines of data, how to conduct which for sure? Numerical general design flow and design and performance head should be listed in the table in the middle row accordance with, or close to, but must fall on the range of two lines, because the range of high-efficiency pump operation area, This type of pump is considered to be in line with the actual needs of the pump be selected.
