Q: When do you choose 2900 RPM centrifugal pumps and when do you choose 1450 RPM centrifugal pumps?
A: Industrial pump most will choose 2900r.p.m pump, 1450r.p.m or lower speed pump pump body volume is relatively large, generally used for low head large flow conditions, due to the low speed of the pump, for easy wear, worry about crystalline particles are broken materials can be considered. With small flow and large head, it is recommended to use 2900r.p.m pump, after all, the investment will be much lower.
