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.
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.
- 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
Field of application

Information for use in areas at risk from explosion
Only use pumps with the appropriate labelling in line with the ATEX Directive 94/9/EC in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label corresponds to or is better than the conditions prevalent in the intended field of application.
