SPECIAL EXECUTIONS IN TANK TKV VERTICAL PUMP TKV pumps are vertical, centrifugal multistage pumps connected to the drive ( generally an electric motor) by flexible coupling. Alignment and drive of line shaft is ensured by bush bearing located in pump casing and by the column pipe joints. Pressure seal at shaft connection is ensured by packing seal. The impeller is a centrifugal type. IN BARREL TKVB VERTICAL PUMP TKVB pumps are canned centrifugal multistage vertical pumps. Vertical axis alignment is ensured by special smooth bearings in the pump, in the support and in the guides interposed...
