Trang 1EN733 (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
