Motor Driven Diaphragm Pumps

Sigma/ 3 Series


New Technology, Durable Design

The ProMinent® Sigma/ 3 is a mechanically-actuated diaphragm metering pump capable of flow rates from 46 to 264 gph (174 - 1000 l/h) and pressures up to 174 PSI (12 bar). The entire Sigma motor-driven metering pump product range, control type S1Cb/S2Cb/S3Cb, has been equipped with intelligent features to provide a high level of operating convenience, safety and efficiency. The pump series comes with a removable HMI operating unit for complete system integration. 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

Features

  • Certified to NSF/ANSI 61 (PVDF liquid ends)
  • Universally compatible PVDF liquid ends
  • Variable AC frequency combined with digital stroking frequency
  • The individual pump functions are simply adjusted using the five programming keys
  • A large backlit LCD indicates the current operating status.
  • 3-LED-function as operation indicators, alarm indicator and fault indicator
  • Connection to complex process control systems with PROFIBUS┬«-DP interface
  • Control via contact or analog signals
    (e.g. 0/4-20 mA)
  • Optional 2-week-process timer
  • Integrated multi-layer safety diaphragm (standard) with visual rupture indicators

Sigma/ 3 Types

Basic type:

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 or 3P signal is possible with optional servomotor. Control of stroke frequency via analog signal is possible with variable speed drives (DC/SCR or AC inverter).

Control type:

Pump settings are programmable on a removeable HMI operating unit. Functions include stroke frequency, batch delivery and external control by pulse or analog signal. The Sigma/ 3 control version features information displays for flow rate (in gph or l/h) and totalized flow (gallons); accumulative stroke count with clear/reset capabilities; and stroke length adjustment displayed in increments of 1%. Three LED lights indicate operating status. Options include a programmable access code, flow monitoring, fault and pacing relays, calibration, timer and 4-20 mA output.

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.
