This vertical tubular casing pump stands on the bed of the pumping chamber. It transmits its own weight, the weight of the water in the propeller and the weight of the motor to the bed via its housing and housing base.

For the highest delivery rates; This vertical tubular casing pump has supports or is installed on a reinforced concrete floor with a supporting frame. Its use is recommended in cases where there is no solid pumping station bed to accommodate the vertical version (VP) or the bed is too deep down.  This propeller pump achieves the highest delivery rate of all KÖSTER pumps. It is suitable for the conveyance of pure or pre-treated, predominantly chemically-neutral fluids at temperatures of up to 60°C. This type of pump is used primarily in pumping stations for irrigation and drainage, for precipitation and mixed water, in waterworks and in industrial water supply systems.

For docks, locks and cooling towers; The construction of vertical, single-stage mixed flow pumps is very similar to that of propeller pumps. However, due to the different shape of their impellers, mixed flow pumps can lift very large volumes of water to delivery heights of up to 30 m. Impeller and diffuser are submerged in the pumping medium. The open impeller has a fixed, cast-on blading. Mixed flow pumps convey pure or lightly contaminated fluids, typically in pumping stations for precipitation and mixed water, hydroelectric power plants and other power plants, in docks and locks as well as in industrial water supply systems.

This single-stage horizontal underwater pump has an automatic coupling to the discharge pipe. It can be mounted and dismounted while the pump chamber is flooded. The pump is guided here on a special rod. Due to the horizontal orientation of the pump, the pumping medium flows in the discharge pipe without being deflected by the pump. The motor is installed on the suction side, so the motor cables lie in the quiet body of water and are not mechanically stressed by turbulent flows.

This propeller pump can be installed in pipe systems horizontally or vertically. It is therefore recommended for plant construction, because the pumping medium in this case already flows via a pipe system. This type of pump has an optional extractable rotor assembly, a feature that makes maintenance and cleaning work a lot easier.  This circulation pump is suitable for the conveyance of water and aqueous fluids such as leaches, dilute acids, brines in closed pipe systems of industrial plants. This type of pump is used primarily in wastewater treatment plants, in which biological treatment is carried out after the activated sludge process, in which the flows (return activated sludge, recirculation) are moved permanently "in a circuit". It is equally suited for use as a so-called booster pump, where it simply increases the pressure in a pipeline.

KÖSTER has been producing hand winches for almost 100 years and continues to carefully manufacture its primary components made of iron and nodular graphite casting in its own, highly-modernised foundry. This knowledge of manufacturing is rare within the winch market. It has also become a kind of unique feature of KÖSTER as well as the guarantee for the outstanding characteristics of our manual winches – reliable quality, exceptionally high stability as well as reliability and durability.
