4、 Installation technical requirements:

All water pumps are equipped with a base. When the pump room is set on the bottom floor, it can be directly installed on the concrete foundation with anchor bolts.

If installed on a floor or in situations where high isolation pads are required, a combination of spring dampers and rubber deceleration pads can be used for better vibration reduction effect.

Rubber flexible joints must be installed at the inlet and outlet pipe ends of the water pump, and the weight of the pipeline system must not be added to the water pump. The inlet and outlet pipes should be fixed with elastic hangers.

1. The pump unit is horizontally placed, and a metal pad is used to level the anchor bolt hole under the base. The nut is tightened, and cement is poured to fix the base firmly. The installation prevents unstable three-point contact of the base.

2. Connect the motor power supply, and the motor should rotate in the direction indicated by the arrow on the bracket (when viewed from the motor end, the rotation direction is clockwise)

3. The inlet and outlet of the pump should be connected to tap water, and the diameter of the pipe should be the same as the inlet diameter of the pump. The inlet and outlet pipelines should have good neutrality and appropriate length, and the pump should not be subjected to significant external forces.

4. Before starting, the following preparations should be made:

Rotate the motor shaft by hand, and the rotation should be flexible without any jamming phenomenon.

Before starting pump B, the pump should be filled with medium.

The allowable leakage rate of the C seal is 5ml/h. If it is considered that the leakage rate of the seal is too large, replace the mechanical seal.
