The Rotor
seepex rotors are characterized by high-quality surfaces. To ensure this
quality and guarantee the corresponding surface qualities, state-of-the-art
machining, abrading and coating procedures are required. Using various grinding
and polishing procedures, the surface roughness depth is reduced, which
enhances the wear and corrosion resistance as well as the friction and hardness
characteristics.
Advantages of an optimum surface
Reduction of the starting torque and operation torques
Improvement of the hydraulic-volumetric efficiency
As a rule, seepex stators are manufactured individually for every size and
pressure stage. Stators made to specification makes it possible to manufacture
stators with sealing flanges on both pipe ends.
This reliable seal protects the stator against
torsion and prevents medium from penetrating the rubber-metal connection.
This seal is mandatory when handling toxic or aggressive products and
to meet the high hygienic requirements of the food industry.
Only the perfect interaction between rotor
and stator guarantees high degrees of efficiency and low driving power.
For this reason, the consistent geometry between the two conveying elements
is crucial. The optimised production process with corrected cores prevents
strong tapering at the ends of the stator. The result is an even dimensional
run along the entire length of the stator.
Advantages of the optimised Stator
High volumetric efficiency rates
Low driving powers
Low starting and operation torques
High pressure stability across the entire speed range
Reliable sealing
Service-friendly; additional gaskets are not required
