Product description

The intelligent pump for safe and reliable use in many applications.

The Sigma/ 1 Control diaphragm metering pump together with pumps of type Sigma/ 2 Control and Sigma/ 3 Control represent an integrated product range. They cover the capacity range from 17 to 1,040 l/h. The entire Sigma Control product range is equipped with intelligent features to provide a high level of operating convenience, safety and efficiency. The pump features a removable operating unit and adjustable metering profiles Metering profiles guarantee optimum metering results by adapting the metering behaviour of the ... more in the glossary to ensure optimum metering results.

Your benefits

Excellent process safety and 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 and reliable operation by bleed option during the discharge process.
  • Metering reproducibility is better than ± 2 % with a 30 - 100 % stroke length adjustment range under certain defined conditions and with proper installation.

Flexible adaptation to the process:

  • Detachable operating unit with large illuminated LC display for outstanding user convenience.
  • Metering profiles for optimum metering results.
  • The Sigma product range is available in a "Physiologically safe in respect of wetted materials" design and with electro-polished stainless steel dosing head and EHEDG certification for applications with strict hygiene requirements.
  • ProMinent Motor Driven Diaphragm Pumps Sigma

  • Motor Driven Pumps Sigma - Metering profiles for optimum metering results

Field of application

  • Volume-proportional addition of chemicals in water treatment, e.g. sodium-calcium hypochlorite for the disinfection of potable water
  • 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

    • For reasons of safety, provide suitable overload protection mechanisms in all mechanically deflected diaphragm metering pumps.

    Detachable Operating Unit (HMI)

    The operating unit (HMI) can be attached directly to the metering pump or mounted on the wall alongside the pump. This provides the operator with a range of options for the integration of a metering system in the overall system that it is readily accessible and easy to use. Moreover the removable operating unit offers additional protection against unauthorised operation of the metering pump or against modification of the pump settings. The operating unit can, for example, be completely removed for project applications.

    Individual functions of the metering pump can be easily selected and adjusted with five program keys. An illuminated LCD display provides information about the relevant operating status. LEDs on the operating unit and the control unit indicate the active pump functions or the pump status.

    Metering Profiles

    Metering profiles guarantee optimum metering results by adapting the metering behaviour of the metering pump to the application or chemical used.

    The stroke motion of the displacement body is continually recorded and regulated so that the stroke is made in line with the desired metering profile. The pump can be operated in normal mode (Diagram 1), with optimised discharge stroke (Diagram 2) or with optimised suction stroke (Diagram 3). Three typical metering profiles are shown schematically with the behaviour over time.

    In normal operating mode (standard), the time behaviour for the suction stroke and the discharge stroke is similar (Diagram 1). In the mode with optimised discharge stroke (Diagram 2), the discharge stroke is lengthened while the suction stroke is made as quickly as possible. This set-up is suited to applications which require optimum mixing and as continuous a mixing of chemicals as possible, for example.

    In the mode with the optimised suction stroke (diagram 3), the suction stroke is carried out as slowly as possible, permitting precise and trouble-free metering of viscous and gaseous media. Select this setting to minimise the NPSH value as well.
