Maintenance-free
- Pressure stability
 Deformation in the rubber leads to higher wear and reduces pressure stability more quickly,
 with the holding pressure in the chambers, backflow 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.
- Pre-stress and pump's operating range
 Maintenance-free stator "Ready-to-go" – pre-stressed for immediate use.
