Hollow rotor
Neuentwicklung von Rotoren für Exzenterpumpen nach dem Prinzip der Drehverdrängung.
What we have developed
In light of the increasing requirements regarding service life and the growing demand for better performance in the area of progressive cavity pumps, we have, for technical and ecological reasons, developed a technology that allows us to use a casting method to manufacture the rotors of the pumps as hollow rotors.
Hollow rotor
Compared to conventional rotors, the weight can be reduced by up to 70%. This lighter weight of the rotors makes them significantly easier to handle, e.g. during their installation into the stator, which can be performed by a single person without the use of auxiliary equipment.
Casting method
The clear advantage compared to hollow rotors manufactured by means of welding is the homogeneity of the material achieved through the use of the casting method,
which practically eliminates the risk of breaks in the rotor.
2.5 Meter - Our currently longest rotor
Cast blanks: 2.5 m / nominal diameter x,
in comparison one of our standard rotors with 1.4 m / nominal diameter x
2.5 m rotor after machining
