Motor-Driven Metering Pump Sigma/ 3 (Basic type) – Bơm Định Lượng ProMinent

Capacity range 146 – 1,030 l/h, 12 – 4 bar

The patented multi-layer safety diaphragm for excellent process reliability is just one feature of the extremely robust motor-driven metering pump Sigma/3 Basic.

It also offers a wide range of power end versions, such as three-phase or 1-phase AC motors, also for use in ATEX areas.

The robust pump for safe and reliable use

The Sigma/ 3 diaphragm metering pump together with pumps of type Sigma/ 1 and Sigma/ 2 represent an integrated product range.

They cover the capacity range from 17 to 1,030 l/h, with a consistent operating concept, control concept and spare parts management.

A wide range of power end versions is available, including some for use in areas at risk from explosion.

Your benefits

Excellent process 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 overload
Reliable operation ensured by bleed option during the suction process

Flexible adaptation to the process:

The entire Sigma product range is available as standard in a ‘Physiologically safe in respect of wetted materials’ design.
Metering pumps with electro-polished stainless steel metering head enable them to be used in hygienically challenging applications
Wide range of power end versions, also for use in areas at risk from explosion, and different flange designs for the use of customised motors

Field of application

The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.

Volume-proportional addition of chemicals in water treatment, e.g. sodium-calcium hypochlorite for the disinfection of potable water
Addition of chemicals depending on the measured value, e.g. metering of acid and alkali for pH neutralisation in wastewater 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

Technical Details

Stroke length: 6 mm,
Stroke length adjustment range: 0 – 100%
Stroke length adjustment: manually using self-locking rotary dial in 1% increments (optionally with actuator or control drive)
With the right, constant conditions, correct installation and calibration, precision exceeds ±1 %, based on maximum stroke volume.
Wetted materials: PVDF, stainless steel 1.4571/1.4404, special materials on request
Patented multi-layer safety diaphragm with optical diaphragm rupture display (as option with diaphragm rupture warning system via a contact)
Integrated hydraulic relief and bleed valve
A wide range of power end versions are available: Three-phase standard AC motor, 1-phase AC motor, motors for use in Exe and Exde areas and different flange designs for use in customer-specific motors
For areas at risk from explosion II 2G Ex h IIC T3 Gb X or II 2G Ex h IIC T4 Gb X (optional)
IP 55 degree of protection
High-strength fibreglass-reinforced plastic housing with excellent chemical resistance

For reasons of safety, provide suitable overflow devices during installation for all mechanically deflected diaphragm metering pumps.
