Users can now choose from 55 sizes with more than 78 hydraulic systems. The pumps are available in materials including grey cast iron, nodular cast iron and cast steel, stainless steel as well as duplex and special alloys, such as titanium and Hastelloy.

The pumps are characterised by their high output per size and their low energy consumption. The developers placed particular emphasis on good suction behaviour with a low NPSH value in order to minimise the risk of cavitation, enabling smooth and stable pump operation even under difficult operating conditions. This ensures a high degree of reliability and improves the availability of an entire system.

By using the finite element method (FEM), a calculation method for the simulation of solids, the developers were able to achieve a high degree of strength and rigidity of the installed components while at the same time optimising the use of materials. After optimising all hydraulic contours using computational fluid dynamics (CFD), the improvements were verified in extensive test set-ups.

The new seal chamber design allows the installation of gland packings, all common mechanical seals compliant with EN 12756, as well as a large number of cartridge-type mechanical seals. To control and monitor operation, the pumps can be equipped with speed control, vibration and bearing temperature measurement and operating point monitoring.

In line with KSB’s common practice for industrial pumps, every pump is supplied to the customer with the impeller diameter trimmed exactly to the duty point. Impeller trimming combined with the large range of pump sizes available for selection helps ensure that the energy consumption of pumps is kept to the minimum necessary, even if they are run at fixed speed.
