KSB Group extends the portfolio of duplex pumps

25 October 2018

In mid-2018, the KSB Group extended its portfolio by adding a comprehensive programme of vertical turbine pumps. The B Pumps are multistage vertical turbine pumps with a submerged hydraulic system. The pump sets comprise a discharge casing assembly, a column pipe and a pump bowl assembly. Customers can choose from 17 sizes with three different impeller types.

The pump sets cover heads of up to 200 metres and flow rates of up to 720 litres per second. They are available with 1 to 25 stages, with stage casing diameters ranging from 6 to 24 inches. Various designs are on offer, enabling an above-floor or underfloor discharge. B Pumps can be driven by vertically mounted electric motors or via a right-angle gear with a horizontal Diesel engine or electric motor. The maximum permissible speed equals 3500 rotations per minute.

The standard pumps are made of grey cast iron and steel. Special material variants can be completely made of stainless steel, duplex and super duplex stainless steel or customised materials. The intermediate bearings of the pump shafts are lubricated by the used fluid.
