PVHB.CLHB Removable Vertical Pipeline Centrifugal Pump for Hot Water

MAIN PURPOSE

Model PVHB.CLHB vertical centrifugal pump is used for water supply for industries and the high buildings in a city, fire-fighting， pipeline boost, warming and air-conditioning hot-cold water cir collation, remote water transportation and boosted transportation for the technological circulation of production. Series marine pumps are used at cabin bottom to cool water and fight fire. It is able to carry sea water under 120℃ degrees. Fresh water and other none roding liquid.

STRUCTURE

A bold improvement on the design is carried out for the structure of model SLB removable vertical centrifugal curately matched with each other. The external structure of it is formed with motor, joint coupling and pump casing and the driving unit is formed with motor shaft, claw-like elastic clutch bearings inside of the bearing seat, pump shaft and impeller. To maintain it needs only to remove the driving unit under the claw-like elastic clutch, without need of removing motor, joint coupling and pump casing. The pump will not be affected with its performance and can be kept in a stable condition all the time in case of a long-way transportation and use under an awful environment.
