Wear Rresistant Vertical Centrifugal Vertical Submerged Pump
Application and Features:
Type SP pumps are vertical,centrifugal slurry pumps which are submerged in sump to work,They are designed for delivering abrasive,large particle and high density slurries,These pumps do not need any shatt seal and sealing water.They can also be operated normally for insufficient suction duties.
Wet parts of type SP pumps are made of abrasion-resistant metal.
All parts of type SP immersed in liquid are lined with rubber.They are suited to transport the slurry which contains non-edge and abrasive particls.
The pump is a vertical submerged pump, which has a beautiful appearance and is directly installed on the storage medium of the medium to be transported, without additional floor space, thereby reducing the capital investment.
The mechanical seal has been eliminated, which solves the troubles that other submerged pumps need to be repaired frequently due to the wear and tear of the mechanical seal, which saves the running cost of the pump and improves the working efficiency.
It adopts a unique centrifugal double-balanced impeller for conveying clean media without solid particles, with low vibration noise and high efficiency. It adopts an open double-balanced impeller for conveying unclean liquid with solid particles and short fibers. Smooth operation and no blockage.
Working principle:
The vertical motor of the submerged pump is fastened with bolts to the motor base, and is directly driven by the elastic coupling and the pump, the pump body, the intermediate indirect pipe, the pump frame, the outlet pipe and the pipe flange, and is integrally connected by bolts.
On the bottom plate, the pump as a whole is mounted on the container through the bottom plate. The axial and radial forces of the pump (including the water pressure generated during pump operation, the weight of the impeller and the rotor, etc.) are all supported by one-way thrust ball bearings, single row radial ball bearings, and sliding guides. The shaft is to withstand the safe operation of the pump. The bearings are lubricated with butter and the guide bearings are lubricated with the liquid being delivered.
Therefore, the liquid level must be higher than the impeller center line during operation. The length of the length L of the container is different, and is divided into an intermediate guide bearing structure and a structure without an intermediate guide bearing. The structure of the new submerged pump is that the pump and the motor are connected to each other and submerged into the liquid to achieve accurate delivery of the material to the target storage.
