EMEC PRISMA 20-05-EPDM Modbus Digital Stepper Motor Chemical Dosing Pump

Stepper motor dosing pump, 5 l/hr @ 20 bar, PVDF pump head, Modbus digital control, PTFE diaphragm, EPDM seals

The EMEC PRISMA 20-05-EPDM Modbus is a high-precision digital stepper motor chemical dosing pump engineered for advanced industrial and water treatment applications requiring accurate, repeatable, and remotely manageable chemical injection. Utilizing microprocessor-controlled stepper motor technology, the PRISMA series delivers smooth low-pulsation dosing with exceptional precision and operational stability.

Delivering a dosing capacity of 5 L/h at 20 bar, this model is ideal for high-pressure alkaline chemical dosing and automated industrial dosing systems. The PVDF pump head provides excellent resistance to aggressive chemicals, while EPDM seals ensure superior compatibility with alkaline media and water treatment chemicals.

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

Integrated RS485 and Modbus RTU communication capability allows seamless integration into automated industrial control systems and remote monitoring platforms. With a turndown ratio of 1:4800 and Slow Mode functionality, the PRISMA Modbus series ensures highly accurate dosing performance even in demanding operating conditions.
