7.5 hp vertical centrifugal pump with 16.3m3/h maximum flow, 52m maximum head, and 50mm diameter of inlet and outlet.
Features:
- The centrifugal pump has a vertical structure. The diameter of the inlet and outlet are the same. 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.
- It is easy to install and maintain. There is no need to dismantle the pipeline system, just lift off the conjunction flat nut of the vertical pump. Then, all the rotor parts can be taken out.
- A vertical centrifugal pump can operate in series or parallel connection according to the requirements of flow and head.
- A vertical pump can be installed vertically or horizontally according to the requirement of the pipeline system.

Tips: Operation steps of stopping the centrifugal pump
- The impeller of the centrifugal pump is the most important component of the centrifugal pump. To avoid the water flow backward in stopping, the outlet valve should be closed first to prevent the impeller from being damaged.
- 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 in every 20 to 30 minutes until the temperature of the pump drops to 50℃.
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 kept 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. - After turning off the centrifugal pump, we should notice if the noise and vibration generated in 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.
- For the centrifugal pumps conveying the crystallization, solidification, and sedimentation media, blockage should be avoided after stopping the pump. Please use clean water or other media to wash the pump and pipe on time.
- Drain the inventory liquid in the centrifugal pump to avoid corrosion and frost crack.
Attentions:
- After stopping the centrifugal pump, the clean work will still be done well.
- In cold weather, especially as to the outdoor pump, the liquid in the pump should be drained immediately to avoid freezing and breaking the pump body.
- The reserved centrifugal pump should be regularly started.
