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.
