10 hp vertical centrifugal pump with 65m3/h maximum flow, 35m maximum head and 80mm diameter of inlet and outlet.


  1. The centrifugal pump has the vertical structure. The diameter of the inlet and outlet are the same. And the inlet and outlet are on the same center line, so that the vertical centrifugal pump can be installed in the pipeline like a valve. If a protective cover is added, it can be used in the open air.
  2. It is easy to install and maintain. No need to dismantle pipeline system, just lifting off the conjunction flat nut of vertical pump. Then all the rotor parts can be taken out.
  3. Vertical centrifugal pump can be operating in series or parallel connection according to the requirements of flow and head.
  4. Vertical pump can be installed in vertically type or horizontally type according to the requirement of pipeline system.

Tips: Daily maintenance of the centrifugal pump

  1. In the operation process of the centrifugal pump, the bearing temperature should not exceed the ambient temperature by 35℃, and the maximum temperature should not exceed 80℃.
  2. Add bearing lubrication oil to the centrifugal pump bearing, observe the oil level to be at the central line of the oil mark, regularly exchange and supplement the lubrication oil.
  3. Screw out the diversion plug screw of the centrifugal pump, fill and diverse water (or tick liquid guiding).
  4. Close the brake valve of the centrifugal pump water outlet, outlet pressure meter and inlet vacuum meter.
  5. Inch the motor of the centrifugal pump, check if the motor revolving direction is correct or not.
  6. Turn on the centrifugal pump motor, and turn on the outlet pressure gauge and inlet vacuum pump when the centrifugal pipeline pump has normal operation, gradually open the brake valve and check the motor load conditions when the gauges show the appropriate pressure.
  7. Try to control the flow and head of the centrifugal pipeline pump within the range indicated on the nameplate to ensure that the pipeline pump runs at a high efficiency point in order to obtain a large energy saving effect.
  8. Immediately stop the machine in case of an abnormall sound of the pipeline.
  9. If the centrifugal pipeline pump is going to be stopped, please firstly turn off the brake valve, pressure gauge and then the motor.
  10. Please check if the pipeline pump, pipeline and the connections have any looseness, rotate the pipeline pump manually to check if the pump is flexible.
  11. Regularly check the wearing condition of the pump sleeve, replace timely in case of a serious wearing.
  12. When the centrifugal pipeline pump is used in severe winter, it is required to unscrew the drainage screw in the lower part of the pump body to avoid frost crack.
  13. If the centrifugal pump is going to be stopped for a long period, the pipeline pump should be completelly dismantled, and dried. The rotary parts and combination parts should be smeared with gear for appropriate storage.
  14. In the first month of the centrifugal pump operation, the lubrication oil should be exchanged every 100 hours, and then every 500 hours.
  15. The centrifugal pump stuffing glland should be regularly regulated to ensure the normal dripping conditions of the stuffing chamber.
