Description of Bare Shaft Centrifugal Pumps

XA series bare shaft single stage centrifugal pumps, which is a back-open type pumps, dismantle the pump cover and the impeller without to take out the suction and discharge piping, in the bearing bracket, there are two ball bearings which lubricated by oil or grease. The mechanical seal and packing universal external installed are optional upon request,  the pump is driven through the flexible coupling from a motor direct.

The volute casing, foots and both suction and discharge flanges are cast integrally in one piece.

Back-Pull-Out Design 

XA series bare shaft centrifugal pumps with feature allows the whole rotating element to be removed for maintenance without disturbing pipework, it is befect for maintenance and installation.

High Interchangeability

Most of the XA seres bare shaft centrifugal pump’s parts are interchangeable, reduce the cost of operation.

Excellent Bearing Housing Design

Incorporated with lifting eye to simplify removal of the rotating element during maintenance, “safe guards” are installed to prevent rotating shaft from human reach while in operation.
