The installation elevation of water pump must meet the requirements

1, in the lowest operating water level, must meet the different operating conditions of the pump to allow suction on the vacuum height or required cavitation allowance. When the motor and pump rated speed is not at the same time, or in the sediment-laden water source to take water, should be allowed to suction the pump on the vacuum height or the necessary cavitation allowance to be corrected.
2, axial-flow pump or mixed-flow pump vertical installation, the minimum submergence depth of its base surface should be greater than 0.5m.
3, into the pool is strictly prohibited to produce harmful eddy.
