Smooth running over the entire

operating range

■n Short bearing span

■n Stiff rotor

■n Low vibrations

■n No cavitation

Extended lifetime

■n No cavitation over the entire operating range

through special contour of inlet area and vanes

■n Mechanical seals well-proven for high speeds

Tailor-made hydraulics

■n Precision machined impeller

■n Optimum adaption to customer’s specific requirements

■n Extremely small flow differential / deviation

in paralleloperation

Quick and easy maintenance

■n Back pull-out pump internals

■n Well-proven mechanical seal in cartridge design

■n Shrunk-fit shaft coupling prevents fretting corrosio

(optional: spline-face connection without shaft keys)

Reduced source of interference

■n No pre-heating necessary thanks to ability

to be started from cold or from hot stand-by

Low life cycle costs (LCC)

■n Low energy consumption

■n Long maintenance intervals

■n Lower foundation loads and smaller crane

capacity due to less weight
