Stepper Motor Drive

Reliable dosing of chemicals

Stepper motor driven diaphragm pumps are particularly suitable for highly accurate, reproducible applications due to their design. Most chemicals can be safely fed into the respective processes using these pumps.

The Encore® S is available in four sizes for metering applications ranging to 19.68 lph against pressures of up to 16 bar.

The compact stepper-motor pump, coupled with its intelligent drive concept, combines the big advantages of a solenoid-driven diaphragm dosing pump with the precision of a motor-driven diaphragm dosing pump.

A wide range of materials and connections are avail- able to comply with specific applications. By using appropriate and recommended materials, the Encore® S can be used in many process applications.

Matching accessory kit with hoses, injection nozzles and suction lines from our comprehensive accessory range means that nothing stands in the way of a quick installation, and you get the best results.
