7.5 hp Vertical Centrifugal Pump, Single Stage

Factory price 3 phase 7.5 hp vertical centrifugal pump has optional input voltage AC 220V~480V and input frequency 50Hz/60Hz, 16.3m³/h maximum flow, 52m maximum head and 50mm diameter of inlet and outlet.

Features:

• The centrifugal pump has a vertical structure, and its inlet and outlet have the same diameter. The inlet and outlet are on the same centerline so that they can be installed in the pipeline like a valve. If a protective cover is added, it can be used in the open air.
• Easy to install and maintain. There is no need to dismantle the piping system, just remove the connecting flat nut of the vertical pump. All rotor parts can then be removed.
• The vertical pump can be installed vertically or horizontally according to the requirements of the piping system.
• Vertical centrifugal pumps can be run in series or in parallel according to the requirements of flow and head.

Tips: Operation steps of stopping the centrifugal pump

1. The impeller of the centrifugal pump is the most important component of the centrifugal pump. In order to avoid the water flow backward stopping, the outlet valve should be closed first to prevent the impeller from being damaged.
2. After the centrifugal pump stops operating, the inlet valve of the pump should be closed. When the centrifugal pump cools down, the valves of the auxiliary systems should be closed successively, otherwise, the centrifugal pump will be damaged.
   The high-temperature centrifugal pump should be stopped according to the technical documents of the equipment. After stopping, it shall be stopped for half a circle every 20 to 30 minutes until the temperature of the pump drops to 50℃.
3. In stopping the low-temperature centrifugal pump, when there is no special requirement, the pump should be filled with liquid, and the suction valve and discharge valves should be maintained open. For the low-temperature pump with double mechanical seals, the liquid level controller and the sealant in the pump seal chamber should maintain the pump's grouting pressure.
4. After turning off the centrifugal pump, we should notice if the noise and vibration generated in the pump start-up will disappear quickly as the centrifugal pump is turned off. If it disappears quickly, it proves that there is a stuck phenomenon inside the centrifugal pump and the pump should be checked and maintained in time.
5. The centrifugal pumps convey the crystallization, solidification and sedimentation media, blockage should be avoided after stopping the pump. Please use the clean water or other media to wash the pump and pipe timely.
6. Drain the inventory liquid in the centrifugal pump, and avoid corrosion and frost crack.

Attentions:

1. After stopping the centrifugal pump, the clean work shall still be done well.
2. In cold weather, especially the outdoor pump, the liquid in the pump should be drained immediately to avoid freezing and breaking the pump body.
3. The reserved centrifugal pump should be regularly started.
