Bag pump

Bag pumpsummary:

1) This vertical drum bag pump is a multi-stage, radial split structure. The type of impeller is a single suction structure, segmented guide vanes, and single-stage shell. To improve the anti cavitation performance of the pump, the impeller adopts a suction impeller.

2) The axial force is balanced by the balance disk device, and the residual axial force is borne by the paired centripetal thrust ball bearings.

3) The shell bears the inlet pressure, and the length of the shell and the installation depth of the pump depend on the requirements of the cavitation allowance of the device. At the same time, the pump can also be used as a multi-stage pumpSubmersible pumpTank pumps and multi-stage pumpsPipeline pumpuse. When used as a multi-stage submersible pump, the pump can be installed in the medium tank without the need for a casing. When used as a tank pump, it can be installed on a container, which serves as the outer shell of the pump. When used as a multi-stage pipeline pump, standard horizontal inlet and outlet structures can be adopted, or the casing can be removed and the suction flange can be directly installed at the lower part of the pump to connect with the pipeline.

4) From the motor end, the pump rotates counterclockwise.

5) The large oil storage chamber of the bearing housing is equipped with an independent internal circulation automatic lubrication system, and a lubricating oil cooling system can be configured according to the temperature condition of the conveying medium. During the maintenance process of mechanical seals or balancing components, the bearing components can be removed as a whole from the pump without the need for separate disassembly, simplifying the maintenance process.

6) When the insertion depth of the pump reaches a certain depth, the pump shaft has a middle support, but there is no contact point as a whole, with a rigid design.

Containerized mechanical seals can be designed in single end face and series connection forms, or dry gas seals can be used according to the medium conditions and owner requirements.

At present, our factory's corrosion-resistant materials can meet the requirements of various media. When placing an order, please provide detailed information about the medium to be conveyed.

The vertical drum bag pump is multi-stage and radially split. The impeller is in the form of a single suction radial type and equipped with a single-stage shell The first stage impeller is generally a suction impeller.

The axial force is borne by the centripetal thrust ball bearing. In the case of a large pressure difference, the balance drum device balances the axial force, and the outer shell only bears the inlet pressure. The length of the outer shell and the installation depth of the pump depend on the requirements for NPSH cavitation performance.
