If it is found to be loose, it should be tightened in time to avoid abrasion of the connection or loss of the handwheel and nameplate. If the handwheel is lost, it is not allowed to replace it with an adjustable wrench, and it should be completed in time. The packing gland is not allowed to be skewed or pre-tightened. For valves in environments that are easily contaminated by rain, snow, dust, sand and other pollutants, a protective cover should be installed on the valve stem. The scale on the valve should remain complete, accurate and clear. The lead seal of the valve, the cap of the pressure reducing valve, and the pneumatic accessories should be complete and intact.

The motor shaft is directly connected to the pump shaft through the pump head with a shaft coupling. Between the head and the water inlet and outlet sections, the inlet and outlet of the pump are on the same line at the bottom of the pump; the pump can be equipped with an intelligent protector as required to effectively protect the pump from dry running, phase loss, and overload.
