Troubleshooting edit failure of a water pump does not absorb water pressure gauge and vacuum gauge pointer severe beating reasons: 1. Perfusion enough water piping and instrumentation 2. 3. The suction coupling at the leak is too high Remedy: 1. Check the bottom valve leaks. to hire enough water 2. Tighten the leak at 3. Reduce suction lift pump failure two non-absorbent vacuum gauge indicates high vacuum reasons: 1. Bottom valve does not open or have too much resistance suction line clogged 2. 3. filter clogging solve Measures: 1. Check the bottom valve 2. Replace the water-absorbing 3. Clean the filter multistage centrifugal pumps with single-stage centrifugal pumps are centrifugal pumps. The pump can take a series of ways to improve lift MD46-50X8 wear multi-stage pump, its head is superimposed relationship, with the same specifications as the size of the impeller MD46-50X6 wear multi-stage pump, packed in the same pump series, (the same axis, Its pump housing chamber to take some separated liquid passage was not the first phase) became the multi-stage pump, of course, single-stage pump multistage pump relative terms. MD46-50X8 wear multi-stage pump, wear multi-stage pump, pump wear mine by Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd.
