EN733 (DIN 24255) 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
Feature allows the whole rotating element to be removed for maintenance without disturbing
pipework.

High Interchangeability
Most of the 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.

Application:
General purpose water transfer and pumping
Pressure boosting and water supply
Chilled & condenser water circulation in central air-conditioning system
Circulation in hot water systems
Machine cooling water circulation
Swimming pool
Fire-fighting & fire sprinkler applications
Irrigation and drainage
