40 hp horizontal centrifugal pump with 32.5m
3/h maximum flow, 127m maximum head and 65mm diameter of inlet and outlet.
The centrifugal pump has the horizontal structure. The diameter of the inlet and outlet are the same. If a protective cover is added, it can be used in the open air.
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.
Horizontal centrifugal pump can be operating in series and parallel connection according to the requirements of flow and head.
The installation angle of pump outlet can be 0°, 90° and 180° to meet different connection occasions.

The single-stage pump refers to a pump with only one impeller. The general single-stage pump has a high head of 125 meters (410ft). It has the advantages such as the simple structure, stable performance, high speed, small size, light weight, high efficiency, large flow, easy operation and maintenance and so on. Tips: What is the single-stage centrifugal pump? Classification of the single-stage centrifugal pump According to the installation position of the motor, it is classified into: horizontal single-stage pump and vertical single-stage pump. According to the flow pass of suction, it is classified into: single-stage single-suction centrifugal pump, single-stage double-suction centrifugal pump. Constitution of the single-stage pump The single-stage pump includes a pump body, a pump cover, an electric motor with an output shaft, a pump shaft, a bearing housing, an impeller, a mechanical seal and a machine gland mounted in the single-stage pump body. It still has the characteristics that it includes a double-clip coupling set between the motor output shaft and pump shaft, as well as the pilot bearing supporting the pump shaft, which is mounted on the bearing seat. The above-mentioned double-clip coupling is rigidly connected to the motor output shaft and the pump shaft, respectively. In addition, a space is reserved between the motor output shaft and the pump shaft to facilitate mechanical seal and machine seal gland assembly and disassembly. Therefore, there is no need to disassemble the motor and the pump cover in repairing or exchanging the mechanical seal.
