Rotor/stator D 5-2.5 The gentle solution

Rotor/stator TWISTER D 5-2.5
  • Rotor/stator D 5-2.5 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

TWISTER

  • Maintenance-free
    ...ready-to-go - operational immediately after installation
    Preset tension enables immediate use
  • Low operating temperature
    ... has a "cool" approach to work
    Friction causes heat and this has an impact on the rubber of the stator. Therefore it is important to reduce the heat
    in the stator through the appropriate rubber mixture and fast heat dissipation.
  • Pressure-resistant
    ... withstands any pressure
    The constant rubber wall thickness of the stator guarantees uniform rubber stress and
    a continuous conveying output over a broad pressure range.
  • Long service life
    ... runs and runs and runs
    The rotor with the highest wear resistance on the market due to extremely high chrome carbide content.
    Fully hardened solid material guarantees high wear resistance even after long running times.

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.
