Installation instructions for GW pipeline sewage pump
1．GW vertical sewage pipeline pumpThe pipeline should have its own supporting components, and the weight of the pipeline should not be applied to the pump.

If a check valve is installed on the discharge pipeline of the GW sewage pump, it should be installed outside the intermediate valve.

For the convenience of maintenance and safe use, a regulating valve is installed on the inlet and outlet pipelines of the pipeline sewage pump, and a pressure gauge is installed near the pump outlet to ensure that the pump operates within the rated head and flow range, ensuring the normal operation of the pump and improving its service life.

4. When installing a pipeline sewage pump, the foundation bolts must be tightened to avoid the impact of vibration on pump performance during start-up.

5. In order to prevent the pump from experiencing thermal deformation of the pipeline when transporting high-temperature liquids, the foot bolts of the pump seat should not be fixed. When the pipeline system expands and contracts, the pump should be able to move together with the pipeline.

6. The inlet and outlet connection flanges of GW type unobstructed pipeline pumps shall be designed according to the 684216-84 standard, and the pipeline flanges shall be equipped with the same regulations.

After the installation of the pipeline sewage pump, the pump shaft should be moved, and the impeller should have no friction sound or jamming phenomenon. Otherwise, the pump should be disassembled for inspection and maintenance.

Before installing the GW type vertical sewage pipeline pump, the fastening and damage of the pump and motor should be checked.
