Motor-driven metering pumps

Motor-driven metering pumps need to be robust, reliable and able to run on their own without supervision. Metering pumps with mechanically actuated diaphragms can be used almost universally in low pressure ranges. And what about servicing? Minimal. Precision? Uncompromising. Value for money? The best you can get.

Motor-Driven Metering Pump Sigma/ 1 (Basic type)
The Sigma/ 1 Basic is an extremely robust motor-driven metering pump with patented multi-layer safety diaphragm for excellent process reliability. It 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.

Capacity range 17 – 144 l/h, 12 – 4 bar

Motor-Driven Metering Pump Sigma/ 2 (Basic Type)
Robust motor-driven metering pumps like the Sigma/2 Basic guarantee excellent process reliability with their patented multi-layer safety diaphragm. The diaphragm metering pump offers a number of power end versions, also suitable for use in areas at risk from explosion.

Capacity range 50 – 420 l/h, 16 – 4 bar

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

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