Design sez

Vertical tubular casing pump with open mixed flow impeller. Pump inlet with bellmouth or suction elbow, pull-out design available, discharge nozzle arranged above or below floor, flanges to DIN or ANSI standards available.

Application pump sez

Handling of raw, pure, service and cooling water in industry, water supply systems, in power stations and seawater desalination plants.

Technical data

  • Q max65,000.0 m³/h
  • H max33.0 m

Drive pump sez

Normally the pump is direct driven by an electric motor. In case of low speed via a spur–or planetary gear (optional).

Desing Details pump sez

Vertical tubular casing pump with mixed flow impeller.
Inlet via suction nozzle or intake elbow. Discharge
branch above or below floor level (optional). Shaft
bearings made of wear–resistant KSB RESIDURR
ceramic material. Pull–out type optional.

Shaft Seal

Asbestos–free soft packing. The shaft has removable sleeves in the vicinity of the seal.


The shafts are connected with disc couplings. The
connection between the pump and the motor is effected with a flexible or adjustable, rigid coupling.

Nozzle Orientation

The discharge nozzle is located horizontally above or below the pump foundation.


As per EN or ASME (AWWA).

Bearings, Lubrication

The shaft is radially supported by wear–resistant
KSB RESIDURR ceramic bearings. The pump is
lubricated by the medium handled. Tilting pad type or antifriction tapered roller bearings with oil–bath lubrication provide axial support and are arranged either in the pump or in the motor (optional).
