EMEC PRISMA 05-28-EPDM Digital Stepper Motor Chemical Dosing Pump

Stepper motor dosing pump, 28 l/hr @ 5 bar, PVDF pump head, digital control, PTFE diaphragm, EPDM seals

The EMEC PRISMA 05-28-EPDM is a high-precision digital stepper motor chemical dosing pump designed for reliable and accurate dosing in industrial and water treatment applications. Utilizing advanced microprocessor-controlled stepper motor technology, the PRISMA series delivers smooth low-pulsation dosing with exceptional repeatability and precise flow regulation.

Delivering a dosing capacity of 28 L/h at 5 bar, this model is ideal for medium-pressure alkaline chemical dosing and industrial water treatment systems requiring stable and highly accurate dosing performance. The PVDF pump head provides excellent resistance to aggressive chemicals, while EPDM seals ensure reliable compatibility with alkaline media and water treatment chemicals.

The intelligent digital control system features a large color display with encoder navigation for easy setup, monitoring, and parameter adjustment. Multiple operating modes including constant dosing, proportional dosing, ppm mode, percentage mode, weekly timer, and external input control provide flexible and highly accurate dosing management.

Its advanced turndown ratio of 1:4800 and integrated Slow Mode functionality ensure homogeneous dosing performance with minimal pulsation, even under demanding operating conditions.
