Motor-Driven Metering Pump Sigma/ 2 (Basic Type)

Capacity range 50 – 420 l/h, 16 – 4 bar

Robust motor-driven metering pumps like the Sigma/ 2 Basic guarantee excellent process reliability with their patented multi-layer safety diaphragm. The diaphragm metering pump offers a number of power end versions, also suitable for use in areas at risk from explosion.

Product description

The robust pump for safe and reliable use.

The Sigma/ 2 diaphragm metering pump, together with pumps of type Sigma/ 1 and Sigma/ 3, represents an integrated product range. 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 ATEX areas.

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 overloading
  • Reliable operation by bleed option during the suction process

Flexible adaptation to the process:

  • The Sigma product range is available as standard in the "Physiologically safe in respect of wetted materials" “F” 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

Field of application

  • Volume-proportional addition of chemicals in water treatment, e.g. sodium-calcium hypochlorite for the disinfection of potable water
  • Addition of chemicals depending on the measured value, e.g. metering of acid and alkali for pH neutralisation in waste water treatment
  • Time-controlled addition of chemicals in the cooling water circuit
  • Pulse-controlled metering in the bottling of different volumes e.g. glycerin filling of manometers

    Technical Details

    • Stroke length: 5 mm,
    • Stroke length adjustment range: 0 – 100%
    • Stroke length adjustment: manually by self-locking rotary dial in 1 % increments (optionally with actuator or control drive)
    • Metering reproducibility is better than ± 2% in the 30 – 100 % stroke length adjustment range under defined conditions and with correct installation.
    • Wetted materials: PVDF, stainless steel 1.4571/1.4404, special materials on request
    • Patented multi-layer safety diaphragm with optical diaphragm rupture display (optionally 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 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)
    • Degree of protection IP 55
    • Highly rigid fibreglass-reinforced plastic housing with excellent chemical resistance
    • For reasons of safety, provide suitable overload protection mechanisms when installing all mechanically deflected diaphragm metering pumps.

    * For the Sigma types 07120, 07220 and 04350, the dosing head is fitted with DN 25 (G 1 1/2) valves. As DN 20 is generally sufficient for the pipework for these types (see technical data, suction/discharge side connector), the connector parts that can be ordered with the identity code (e.g. inserts) are already reduced to DN 20, i.e. DN 20 pipework and accessories can be installed.

    Information for use in areas at risk from explosion

    Only use pumps with the appropriate labelling in line with the ATEX Directive 2014/34/EC in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label correspond to or are superior to the conditions prevalent in the intended application.
