Motor-Driven Metering Pump - Sigma/ 1 (Basic type)

44 Recent Views In Stock

Sigma/ 1 offers a wide range of power end designs, such as three-phase or 1-phase AC motors, also for use in areas at risk from explosion.

The Sigma/ 1 diaphragm metering pump, together with pumps of type Sigma/ 2 and Sigma/ 3, represents 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.

 

Applications for this product

• 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 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

Features of this product

• 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.
• Adaptation to specific installation situations, as the "Liquid end on left" option can be selected as standard.

Why Choose This Product

• 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 to protect the pump from overloading.
• Reliable operation by bleed option during the suction process.

Specifications of this product

• Capacity range 17 – 144 l/h, 12 – 4 bar
• Stroke length: 4 mm.
• Stroke length adjustment range: 0 – 100%.
• Stroke length adjustment: manually by self-locking rotary dial in 1 % increments (optionally with actuator or control drive).
• Metering reproducibility is better than ±2% in the 30 – 100% stroke length adjustment range under defined conditions and with correct installation.
• Wetted materials: PVDF, stainless steel 1.4571/1.4404, special materials on request.
• Patented multi-layer safety diaphragm with optical diaphragm rupture display (optionally with diaphragm rupture warning system via a contact).
• Integrated hydraulic relief and bleed valve.
• A wide range of power end versions is available: Three-phase standard motor, 1-phase AC motor, motors for use in areas at risk from explosion and different flange designs for use in customer-specific motors.
• For use in areas at risk from explosion II 2G Ex h IIC T3 Gb X or II 2G Ex h IIC T4 Gb X (optional).
• Degree of protection IP 55.
• Fibreglass-reinforced plastic housing.
• Liquid end on left is available as standard.
• For reasons of safety, provide suitable overload protection mechanisms when installing all mechanically deflected diaphragm metering pumps.
