Pump selection

This post was last posted by FLYTOINTER on 2010-7-11 22:45 Editor: I want to choose an IH type, 80 cubic meter/hour chemical pump, but I can't find it. Is there an 80 cubic meter/hour chemical pump? If so, what are its specifications and where is it produced? If not, how can I use a 100 cubic meter/hour centrifugal pump with an outlet flow of 80 cubic meters. Each series of centrifugal pumps has an applicable flow rate and pressure range. By changing the rotation speed or the diameter of the impeller, it can meet every operating point within the coverage range. ——by flytointer
The flow rate of IH type chemical pumps can be adjusted. The mark on the nameplate is a point on the pump's characteristic curve, which is usually the point with the highest efficiency. You can choose a pump with a marked flow rate of 100m3/h. The main thing is the choice of lift. You have to calculate the required lift and then you can choose the appropriate pump. You can also check it online. There are many manufacturers' websites that provide pump parameters.

You can negotiate with the manufacturer to cut the impeller to achieve the flow and lift you require.
You can choose a pump with similar flow rate or head and change it by cutting the impeller.
This can be solved by setting up a bypass.
