Motor Driven Diaphragm Pumps

Sigma/ 1 Series


New Technology, Durable Design

The ProMinent® Sigma/ 1 is a mechanically-actuated diaphragm metering pump capable of flow rates from 5.2 to 38 gph (20 to 144 L/h) and pressures up to 174 PSI (12 bar). ProMinent® Sigma/ 1 microprocessor controlled metering pumps are programmable and display comprehensive data for monitoring, recording, and tracking. Functions include digital setting of stroke frequency, manual stroke length adjustment, integral variable speed and access codes. Also available in basic, non-microprocessor based version and explosion proof models.

Applications

  • Time-controlled chemical addition in cooling water circuits
  • Proportional chemical addition in water treatment
    (e.g. Sodium Hypochlorite for drinking water disinfection)
  • Measurement-dependent chemical addition (e.g. acid & caustic metering for pH neutralization in wastewater treatment)
  • Pulse-controlled metering from variable flow meters
  • Chemical process, Mining, Petrochemical, Heavy industrial, Pharmaceutical, Water and Wastewater Treatment
  • Integrated multi-layer safety diaphragm (standard) with visual rupture indicators

Features

  • Certified to NSF/ANSI 61 (PVDF liquid ends)
  • Universally compatible PVDF liquid ends
  • Drive unit is adjustable at 90º angles to the base
  • Optimum combination of variable AC frequency combined with digital stroking frequency
  • Simple adjustment of pump functions via panel programming keys
  • A large backlit LCD indicates the current operating status
  • 3-LED-function as operation indicators, alarm indicator and fault indicator
  • Problem-free connection to complex process control systems with PROFIBUS®-DP interface.
  • Control via contact or analog signals (e.g. 0/4-20 mA)
  • On demand, integration of 2-week-process timer
  • Remote monitoring, diagnostics, control (via fieldbus, analog, pulse and/or timer), access codes, fault/pacing relays, mA analog output, and flow monitoring

Sigma/ 1 Type:

The Sigma/1 microprocessor controlled metering pump (S1Ca) is supplied with an integral TEFC motor. The Sigma basic version (S1Ba) is suitable for simple metering pump applications. The pump may be operated manually by adjusting the stroke length knob (displacement per stroke). Automatic control of displacement per stroke via a 4-20 mA analog signal is possible with an optional servomotor. See identity code for motor options.
Optional servomotor available for automatic control of displacement per stroke (via a 4-20 mA analog signal).

Frequently Asked Questions

Standard Lead Times for Products / Expediting

Standard lead times are listed below. If you need an order expedited, please contact your customer service representative. Please be aware that overnight shipments receive priority over ground shipments. Gala/Beta/Concept - 3 days Sigma series - 5 days ProMus - 2 weeks Dulcometer 3-4 days

When discharging to atmosphere, what steps will improve repeatability of dosing?

Installing a spring in the discharge valve of the pump gives some improvement, but for the maximum improvement, a backpressure valve should be installed at the end of the line.
