sigma (base type)
Capacity range of the series 17 – 1,030 l/h at 16 – 4 bar back pressure
The sigma (base type) is an extremely robust motor-driven metering pump with patented multi-layer safety diaphragm for excellent process reliability. It offers a wide range of power end designs, such as three-phase or 1-phase AC motors, also for use in areas at risk from explosion.
We currently only offer an extract from our product portfolio, other variants are available on request.
Send RequestThe robust pump for safe and reliable use
The basic type of sigma diaphragm metering pump forms a consistent product family with the S1Ba, S2Ba and S3Ba pumps. They cover the capacity range from 17 to 1,030 l/h, with a consistent operating concept, control concept and spare parts management. A wide range of power end versions is available, including some for use in areas at risk from explosion.

Properties / Your benefits
Excellent process reliability:- In the event of an accident, the feed chemical does not escape to the outside nor into the pump's power end, thanks to the patented multi-layer safety diaphragm with optical (optionally electric) signalling.
- Integrated relief valve protects the pump against overload
- Reliable operation by bleed option during the suction process
- The entire Sigma product range is available as standard in a 'Physiologically safe in respect of wetted materials' design.
- Metering pumps with electro-polished stainless steel metering head enable them to be used in hygienically challenging applications.
- Wide range of power end versions, also for use in areas at risk from explosion, and different flange designs for the use of customised motors
- S1Ba: Adaptation to specific installation situations, as the 'Liquid end on left' option can be selected as standard.
- Stroke length: 4 mm (S1Ba), 5 mm (S2Ba) or 6 mm (S3Ba)
- Stroke length adjustment range: 0 – 100%
- Stroke length adjustment: manually using self-locking rotary dial in 1% increments (optionally with actuator or control drive)
- With the right, constant conditions, correct installation and calibration, precision exceeds ±1 %, based on maximum stroke volume.
- Wetted materials: PVDF, stainless steel 1.4571/1.4404, special materials on request
- Patented multi-layer safety diaphragm with optical diaphragm rupture display (as option with diaphragm rupture warning system via a contact)
- Integrated hydraulic relief and bleed valve
- A wide range of power end versions is available: Three-phase standard AC motor, 1-phase AC motor, motors for use in areas at risk from explosion and different flange designs for use in customer-specific motors
- For areas at risk from explosion II 2G Ex h IIC T3 Gb X or II 2G Ex h IIC T4 Gb X (optional)
- IP 55 degree of protection
- Fibreglass-reinforced plastic housing
- S1Ba: Liquid end on left is available as standard
