EMEC PRISMA 04-50-VF SS Digital Stepper Motor Chemical Dosing Pump

Stepper motor dosing pump, 50 l/hr @ 4 bar, stainless steel pump head, digital control, PTFE diaphragm, VF Viton seals

The EMEC PRISMA 04-50-VF SS is a high-precision digital stepper motor chemical dosing pump designed for accurate and reliable dosing in demanding industrial applications. Utilizing advanced microprocessor-controlled stepper motor technology, the PRISMA series delivers smooth low-pulsation chemical injection with exceptional repeatability and precise flow control.

Delivering a dosing capacity of 50 L/h at 4 bar, this model is ideal for industrial chemical dosing systems requiring robust mechanical durability and precise process control. The stainless steel AISI 316 pump head provides excellent strength and corrosion resistance for industrial chemical handling, while VF Viton seals ensure reliable compatibility with acidic and aggressive chemical media.

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

Its advanced turndown ratio of 1:4800 and integrated Slow Mode functionality ensure highly homogeneous dosing performance and precise chemical distribution even in demanding operating conditions.
