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.

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.
