Motor-Driven Metering Pump Sigma X Control Type – Sigma/ 2 - S2Cb

Capacity range S2Cb: 61 – 353 l/h, 16 – 4 bar

The Sigma control type is a smart motor-driven metering pump that is setting new standards in terms of productivity, reliability and safety.

Product description

The new Sigma X family – reliable, smart and with scope for networking

The Sigma X diaphragm metering pump covers a capacity range of 21 to 1,040 l/h in versions S1Cb, S2Cb and S3Cb. Its patented multi-layer safety diaphragm guarantees maximum process reliability. Efficient protection of the power end from overloading by means of an integral frequency converter with microprocessor control(ler).

One highlight is the standardised operating concept with click wheel and 4 additional operating keys on a removable operating unit. A large illuminated LCD and a 3-LED display for operating, warning and error messages, visible from all sides, offers additional operating convenience.

The Sigma, like all smart ProMinent metering pumps, can be flexibly connected to various bus systems.

It has a large adjustment range thanks to a combination of frequency and stroke length adjustment. The pump works with high precision across the entire frequency range. Accurate and complication-free metering of viscous and gaseous media by adjustment of the movement profile.

Operating statuses are simply remotely transmitted via an additional output or relay module. A built-in timer, included as standard, controls time-dependent metering cycles.

Relevant spare parts can be shown in the display. The integral log book significantly improves process management, optimisation and troubleshooting.

Your benefits

  • Safe: 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 overload shut-down in the pump control to protect the pump from overloading and thus significantly reduce pressure surges caused by blockages.
  • External control is scalable via potential-free contacts with pulse step-up and step-down, batch mode or via a 0/4-20 mA standard signal.
  • Flexibly connectible: Connection to process management systems via integral PROFIBUS®, CANopen interface.
  • Integral log book saves up to 300 events and simplifies troubleshooting and analysis of the cause.

Field of application

  • All industrial applications, either as a stand-alone unit or integrated in a complete system
  • Volume-proportional addition of chemicals in water treatment, e.g. sodium hypochlorite for the disinfection of potable water
  • Neutralisation in waste water treatment
  • Pulse-controlled metering in the bottling of different volumes e.g. glycerol filling of manometers
  • With an integrated timer as a control unit for simple processes, e.g. biocide metering in cooling water

    * 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.
