sigma (base type)

Description product group

The 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
Flexible adaptation to the 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.
Technical details
  • 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
For reasons of safety, provide suitable overflow devices during installation for all mechanically deflected diaphragm metering pumps
