Trouble-free operationEven in demanding applications the maintenance-free
encapsulated bearing protects the shaft and bearing area
from solids. For fluids with high sand content, we offer
a high wear resistant material variant.
Increased service life of motorsThe mechanical seal in carbon, ceramic or SiC/SiC material
combination prevents any leakage of motor fluid into the
pumped liquid thus preventing contamination. The pump sets
are selected for maximum performance, thus protecting the
motors against overload.
Reliable pressure balancing systemn Optimum rubber expansion diaphragm designn Enables installation at very low depths
High operating reliability and long service lifeThe check valve with anti-blockage check plate closes quickly
and silently, and reduces water hammer. The water-lubricated
self-aligning tilting-pad journal bearing in the motor ensures
correct bearing function even under high loads.
Tried and tested thrust bearingn Water-lubricated self-aligning tilting-pad journal bearingn No-maintenance design suitable for maximum load-carrying
capacity under continuous operation conditionsn New materials combination (stainless steel/carbon) for high
safety factor
