7.5 hp horizontal centrifugal pump with 7.8m
3/h maximum flow, 72m maximum head and 40mm diameter of inlet and outlet.
The centrifugal pump has the horizontal structure. The diameter of the inlet and outlet are the same. If a protective cover is added, it can be used in the open air.
It is easy to install and maintain. No need to dismantle pipeline system, just lifting off the conjunction flat nut of vertical pump. Then all the rotor parts can be taken out.
Horizontal centrifugal pump can be operating in series and parallel connection according to the requirements of flow and head.
The installation angle of pump outlet can be 0°, 90° and 180° to meet different connection occasions.

After completing preparations, the centrifugal pump can be started. After starting, when the pump speed is stable, check the pressure and current, and pay attention to the vibration and noise. When the ammeter pointer swings to the specified position, the cock of the vacuum gauge and the pressure gauge can be opened, and the outlet valve must be slowly opened, and the water pump starts to have the normal operation. At the same time, the valve of the sealing water pipe should be opened. Tips: Operation steps of centrifugal pump start up The idle running time after the start of the centrifugal pump should not be too long, usually limited to 2 to 4 minutes. If the time is too long, the temperature of the water will rise, which may cause cavitation or other adverse consequences.
