*Higher ratings on request
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
