 Bishop-Wisecarver Corp. has announced the HepcoMotion SBD sealed belt. A stainless steel band runs across the length of the beam, which is held in place by a magnetic strip. The band and strip effectively enclose the linear motion system, minimizing the entrance of dirt and debris. The product is offered in standard and clean room configurations, in 80 and 100 mm beam widths, and in single beam lengths to 6 m. Longer beam units may be created by joining.

HEAVY-DUTY SINGLE-STAGE CENTRIFUGAL PUMPS |
|
 Meeting the American Petroleum Institute’s standard API 610, 10th edition, KSB’s RPH line of heavy-duty industrial pumps is suitable for refinery and petrochemical applications. The centrifugal overhung single-stage pumps feature extra-large diameter drive shafts and bearings that help ensure long, trouble-free service lives. When maintenance is required, the back pull-out design means that the impeller, drive shaft, seal chamber and bearings can be removed for service as a unit – without having to disturb the main body of the pump or any of the piping connected to it.
