Maintenance-free
Pressure stability
Deformation in the rubber leads to higher wear and quickly impacts pressure stability = holding pressure in the chambers; reflux occurs in the stator.
Operating temperature
Friction causes heat and this has a negative impact on the rubber of the stator.
It is therefore important to reduce the heat in the stator by using a suitable rubber compound and through fast heat dissipation.
Irregular rubber thicknesses prevent fast heat transmission.
