The difference between the pump 1, single-stage pump impeller means that only a multi-stage centrifugal pump DG25-30X4 maximum lift only 125 meters; 2, multi-stage pump means there are two or more than two pump impeller, the highest lift up to 1000 m; 3, when the pump head is less than 125 meters to actual needs, according to the pumping station area, pump prices (multi-stage pump is generally higher than the single-stage pump price), and other factors considered in the selection of single or multi-stage pump pump. With advances in technology, centrifugal, single-stage pump impeller can be improved by increasing the pump speed pump head can be replaced by a multi-stage pump, but the price is a little expensive. Caution should be divided into electric pump and machine both for aspects of machine DG12-25X12 multistage centrifugal pumps, mainly the previous maintenance records transferred out than what you know. The second is the power of respect, and to understand each pump motor power DG12-25X11 multistage centrifugal his control system has a certain understanding. Many multi-stage pump series, the appearance, divided into: vertical multistage pumps and horizontal multistage pumps. According to lumber divided into: stainless steel multi-stage pump, lg multi-stage pump, da multistage pump. The difference between the multi-stage and single stage of a multi-stage pump means there are two or more than two pump impeller, the maximum you can lift more than 125 meters. 2, single-stage pump means that only a pump impeller, maximum lift only 125 meters away. lg multi-stage pump, lg type multi-stage pump, lg vertical multistage pumps, da multistage pump, md multistage pump, multistage pump series DG12-25X12 multistage centrifugal pumps, centrifugal pumps, boiler feed pumps from the Yasukuni City Shek Yuan pumps Limited.
