5 hp vertical centrifugal pump with 8.3m3/h maximum flow, 51m maximum head and 40mm 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: Preparation before operating the centrifugal pump
I. Inspection before start-up
In order to ensure the safe operation of the pump, the entire unit should be thoroughly inspected before the pump is started, and problems should be found and dealt with in a timely manner. The inspection contents include the below items.

  1. If the motor is well fixed with the water pump, if the bolt and nut are loose.
  2. If the lubrication oil of each bearing is sufficient, if the lubrication oil goes bad.
  3. If the water pump is firstly used or re-installed, the rotation direction of the water pump should be checked correct.
  4. Check if the liquid pool and filtering net have any foreign object.
  5. Check if the stuffing in the stuffing box is hardened.
  6. Check if the valve on the draining pipe can be opened and closed flexibly.
  7. Check if the electrical wire of the motor is correct.
  8. Check if there is any object hindering its operation around the unit.

II. Preparation before start-up
After the comprehensive inspection and confirming everything is normal, the start-up preparation can be conducted. The works should include the below items.

  1. Close the valve on the drainage pipe, reduce the start-up current.
  2. Open the vent cock, and fill water into the pump, and rotate the coupling manually, exhaust the residual air in the impeller as much as possible, until the cock has water emitted, and close it.
  3. When the vacuum pump is used to exhaust air and fill water for the large-scale water pump, the exhaust cock, and cock of the vacuum meter and pressure meter should be closed to protect the instrument correctness.
