The new KGK series, B80 vertical plastic centrifugal pumps are used to pumping acid solutions, hydroxides, salts in varying concentrations, strong acid mixtures, galvanising solutions, chemical waste fluids, chlorinated hydrocarbons, glycol ether, emulsions, sea water and hot spring water etc. with a delivery rate of up to 80 m³/h and a delivery head of up to 41 m wc at a density of max. 2 kg/dm³.

For the “G” version, the immersed shaft slide tube and the rising tube are clad with PP-GRP (vinylester-reinforced fibreglass). This increases the strength and limits lengthwise expansion. Liquids up to a temperature of 90°C can be pumped, the bearing suppliers load is reduced and the service life of the pump therefore is increased.

The bearing housing is treated with an acid protection paint, is resistant to corrosion and accommodates the elastic fitting with axial and journal bearings. The design was kept as compact as possible, which significantly reduces vibrations. To contain the vapours and gases which arise inside the pump, in the standard version, at the height of the bearer plate, a vapour seal is fitted which works dry, both in static and dynamic conditions. In addition to the standard lip seals which work dry, a mixed seal is also available which has a dynamic deflector ring that works efficiently up to a pressure of about 300 mbar. The innovative “liquid barrier” system can be supplied with pneumatics or liquid via a rapid-action coupling. The laminar spread of the compressed air builds up a counter-pressure, completely blocking poisonous vapours and gases so these can neither get to the mechanical parts nor escape to the outside, thus protecting the environment.
