EMEC PRISMA stepper diaphragm dosing pump, up to 80 L/h, up to 25 bar

EMEC PRISMA is a stepper motor diaphragm dosing pump for precise chemical dosing. The pump controls diaphragm position and speed throughout the suction and discharge cycle, so the flow stays smooth even at low rates. Turndown ratio up to 4800:1, Slow Mode for viscous liquids.

Operating modes: constant, external signal, ppm, %, ml/pulse, pause-work, weekly timer, 4–20 mA, pulse, voltage, batch. Level control, alarm output and standby are provided, Modbus RTU is optional. PVDF or PP head, FKM or EPDM seals, PTFE diaphragm, ceramic valves.

Maximum flow and maximum pressure are not reached at the same time. Typical duty points: 2 L/h at 25 bar, 5 L/h at 20 bar, 7.5 L/h at 16 bar, 13 L/h at 10 bar, 28 L/h at 5 bar, 80 L/h at 2 bar.
