Tips for boiler feed high pressure hot water centrifugal pump installation
 Please take note as below when install the high pressure water pump:
1. The preformed hole on the foundation should be poured as the pump installation drawing.
2. The installation level should meet the demand of the allowed vacuum suction height. The foundation should be in horizontal and stable condition, to make sure the rotation of the driver machinery same with the pump in the direction.
3. When connect by coupling, must make sure the pump and driver shaft center  should be in a straight line.
4. If belt connection, the shaft center should be in parallel.
5. The boiler feed water pump suction pipe should be sealed well, and try to less the quantity of the elbow and check valve. When fill water, exhausted the air. It should be no any air when operate. We need to keep the suction pipe slopes up slightly, and then connect with the pump inlet.
