The KSB Group extended its portfolio by adding a comprehensive programme of vertical turbine pumps. The so-called 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. In total, customers can choose from 17 sizes with three different impeller types.

• The pump sets cover heads of up to 200 metres.
• Flow rates of up to 720 l/sec.
• Available with one to 25 stages,
• with stage casing diameters ranging from six to 24 inches.

KSB experts developed a special impeller for its Movitec multistage high-pressure pumps. This new impeller significantly improves these pumps’ suction characteristics (NPSH value).

It proves its worth particularly in applications with critical inlet conditions (e.g. boiler feed applications) as well as applications in which the pump is required to take in water from low-lying tanks or at higher temperatures. Under these conditions, a pressure drop in the intake area may cause cavitation to occur in the first pump stage. This can result in excessive wear of pump parts or motor bearings as well as a reduced service life of the pump due to damaged parts and an unbalanced hydraulic system.

The new impeller is offered as an alternative to the standard product.

The actually supplied two canned motor pumps, with “tandem” design, convey the medium [C3 fraction with propylene as main constituent] at a temperature of 22 °C. The differential head [H] is 379 m at a flow rate [Q] of 7.8 m³/h. The pump units are designed for a nominal pressure of 40 bar and have temperature- and level-monitoring features. For online monitoring of the hydraulic axial bearing, a rotor-position monitoring feature is also provided.

The special tandem design of the multistage pumps results in minimal shaft deflection and load relief at the slide bearings. The “ZART” (Zero Axial and Radial Thrust) technology ensures a contact- and wear-free running of the rotor unit.
