In favour of a universal configuration of drives through flexible couplings or V-belts, seepex pumps of the NS range do without direct flange-mounting of a drive. They feature a drive casing and a free shaft end, in which case the service-friendly plug-in connection between the rotating unit and the drive shaft of the pump is maintained. This facilitates convenient replacement of the rotating wearing parts and the shaft sealing without dismantling the bearing unit.
