QDL Electric pumps Vertical Multistage stainless steel
centrifugal pump drawing
Summarize:
1.QDL Electric pumps Vertical Multistage stainless steel centrifugal pump drawing is used to transfer clean hot and cold medium without solid and fiber, no-flammable and non-explosive.
2. Inner impeller, case and other major parts are made of high quality stainless steel and bearing bush, shaft sleeve are made of hard steel alloy.
3. It's an advanced pump in stable running with little noise, long service time, small volume and light.
4. The vertical pump can be used as a boiler feeding pump. Widely used in pressure boosting of living water and high building water supply.
5. The stainless steel one could also pump the brackish water, mineral water, distilled water, water of swimming pool or other liquid which is muriatic.
