Design features

        these Multi-stage centrifugal pumps are designed from modular elements Interchangeable for various sizes to render possible an economic spare part Stock keeping.

 

Casing parts

        the Casing parts are sealed against each other by o-rings and secured by external Tie bolts.

Normally suction and discharge casings are Designed with feet below. In the case of hot liquids beginning with size 80(t> 150 degree C) and size 150(t> 110 degree C) the feet are, however, Positioned in pump centerline.

Branch position Normally the discharge is Positioned upwards for all sizes and the suction branch to the right (looking from drive end). Alternative branch positions and additional bleed-off branches At the stage casings are possible.

Hydraulics and compensation of axial thrust for each size two different impeller/diffuser Sets followed by diffusers are available. Thus an optimum efficiency is Obtained in many ranges. Interchangeable wear rings seal the impellers towards the stage the casing. the axial thrust produced by the single suction impellers Is compensated by a hydraulic balancing device.

A design with balancing disc ensures a Complete compensation, if a balancing piston is used the residual thrust is Absorbed by air-cooled antifriction bearings.

Bearings and lubrication

        in the area of the impellers and stuffing boxes the shaft is protected. In the Case of a balancing disc the shaft runs in grease-lubricated antifriction Bearings. Beginning with size 150 and in the case of a balancing piston the Shaft runs in oil lubricated antifriction bearings.

Shaft sealing

        Normally Packed stuffing boxes are used as shaft sealings. Due to the pressure reduction In the balancing device the discharge end shaft seal only seals against the Suction pressure. If required the stuffing boxes can be flush with seals Liquid. for liquid temperatures above 110 degree C the stuffing box area is Cooled, above 130 degree C the stuffing box area is cooled in addition. Mechanical seals are only envisaged for pumps with balancing piston. If Mechanical seals are installed balanced seals according to DIN 24960 have Always to be used.
