What is the difference between a low pressure pump and a high pressure pump?
The magnitude of the pressure at the outlet side of the pump
High pressure pump head, large power! High pressure pump, low pressure pump has no strict limit
The specific speed of the high pressure pump is relatively smaller than the speed.Lift is not the same, the same flow, high pressure pump head high.Pump and shaft materials are not the same, high pressure pump raw material demand is higher, to be able to accept greater pressure and torque.The size is different, the pump body of high pressure pump is larger.Bearings can also be different, low pressure pumps are rolling bearings, and high pressure pump power, then some pumps are selected sliding bearings.The support method can also be different, the low-pressure pump is the pump foot support, but the high pressure pump can be the intermediate support.
