PRODUCT ADVANTAGES

  • Easy maintenance and installation

    The import and export middle lines are on the same horizontal line, and the import and export flanges are the same.

  • Mechanical seals are wear-resistant and durable

    Using hard and wear-resistant tungsten carbide, it has durability, wear resistance, etc.

  • The whole machine can be placed outdoors

    Add protective covers to the fan blades of the motor, without the need for a machine room.

  • reasonable design

    The supporting motor is reasonable, efficient, and has good energy-saving effects.

  • ● Installation and use of GW type unobstructed sewage pump in Jinling Qifeng
    1：Firstly, check if the external fasteners have become loose during transportation.
    2：Check if the power supply voltage meets the requirements of the motor nameplate.
    3：Connect the power and try to turn it on to see if the impeller rotates in the direction indicated on the pump. If the direction is reversed, simply swap any two-phase wires in the cable. During the test run, do not wait too long to avoid burning the seal.
    4：Install the pump and start it up for operation. Could you please install the pump foot screws.


  • ● Troubleshooting of GW type unobstructed sewage pump in Jinling Qifeng
    1：Before using the pump, the insulation resistance of the motor winding to the casing should be checked. If it is lower than 0.5 megohms, the stator should be dried and the insulation resistance should be increased before use.
    2：If the gap between the impeller and the oil seal at the inlet of the pump body exceeds 2mm, the wear-resistant oil seal should be replaced.
    3：When there is water leakage in the pump seal, the seal should be replaced in a timely manner. When replacing, the static seal should be installed flat and solid first, and then the dynamic seal should be sealed on the shaft.
    4：When replacing the impeller, use a puller to pull it out, and do not use a hammer to strike forcefully to avoid damaging the shaft alignment.
