Which brand has good DC-type medium-pressure boiler feed pumps?
Thread Content
When boiler feed pumps used in workshops are operated continuously, over time they tend to experience low outlet pressure, increased current consumption, and reduced flow rate, failing to meet the process requirements; thus a new pump needs to be replaced within less than half a year. After disassembling such pumps, it was found that their middle section had been damaged due to cavitation. Do you have any recommendations for pumps that seem to have better resistance to cavitation? Pump parameters: head 466m, flow rate: 12.5m3/h, required NPSH: 2.5m, shaft power: 37.5KW, speed: 2950r/min. Drum pressure
While the issue encountered by the poster is indeed related to the quality of the pump, it is also connected to the conditions of use and operation. First, check whether your conditions of use and operation are in line with the pump’s instructions.
