3 hp vertical centrifugal pump with 8.3m3/h maximum flow, 33m maximum head, and 40mm 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: Analysis of the low operating efficiency of the centrifugal pump
The loss of liquid flowing through the impeller includes mechanical losses, flow losses, and leakage losses, and the corresponding efficiency of the centrifugal pump is divided into mechanical efficiency, hydraulic efficiency, and volumetric efficiency. The mechanical loss includes wheel dropping losses consumed because of the friction between the impeller wheel cap, the outer side, and the liquid, the friction losses between the bearing and stuffing box, and the leakage losses. The leakage losses include the leakage losses at the impeller sealing ring site and interstage and axial force balance mechanism.
Most of its losses are converted into heat, which shall be absorbed by the fluid afterwards.
Low pipeline efficiency: When the conveyed liquid has changes in flow rate or head, the most common treatment means is to regulate the valve. Although this method is convenient, it still has many disadvantages because it will bring great losses to the pipeline resistance, thus enabling the centrifugal pump to operate under the low-efficiency status.
