Capacity range 2 – 76 l/h, 320 – 12 bar

The plunger metering pump Sigma/2 (Control Type) is an extremely robust metering pump with integral control for analogue and/or contact operation. It offers the option of adjusting the pump capacity in 0.2% increments. It offers a wide range of power end versions, and different flange designs.

Product description

Sigma plunger pump – durable, high-performance and intelligent.

The plunger metering pump Sigma/ 2 (Control Type) (SCKa) is a metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator An actuator is used to move the adjustment spindle for the stroke length adjustment of a ... more in the glossary or control drive. The integrated controller allows the pump to adapt quickly and reliably to changing metering tasks.

Your benefits

Process reliability:

  • Metering reproducibility is better than ± 1% within the 10 – 100% stroke length range under defined conditions and with correct installation

Flexible adaptation to the process:

  • The integrated controller allows the pump to adapt quickly and reliably to changing metering tasks
  • Customised designs are available on request
