Rotor/stator A 2-2.5
  • Rotor/stator A 2-2.5 L mf

The heart of a mixing and delivery pump is the pump unit, also known as the rotor/stator. This is where the required pressure is built up in order to deliver the material to the processing location. Depending on the size, different conveying outputs can be provided. The last digit of the pump designation denotes the number of pressure stages; a working pressure of 10 bar can be built up for each stage. If these values are no longer achieved, the unit is worn out and should be replaced.

Details

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.

Pre-stress and pump's operating range
Maintenance-free stator "Ready-to-go" – pre-stressed for immediate use.
