Motor-Driven Metering Pump Sigma/ 3 (Basic Type)

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

High process reliability:

• In the event of an accident, the feed chemical does not escape to the outside or into the pump drive, thanks to the patented multi-layer safety diaphragm with optical (optional electrical) signaling
• Integrated relief valve to protect the pump against overload
• Reliable function due to venting option during the suction process

Flexible adaptation to the process:

• Variants with EU 1935/2004, FDA or Hygienic Design can be selected for food applications.
• Adaptation to special installation situations, as "liquid end left" can be selected as standard.
• Wide selection of drive variants, also for the ATEX range, and various flange designs for the use of customer-specific motors.
