PRISMA stepper motor-driven dosing pump has been designed by EMEC to be the best solution for offering high-accuracymetering and extreme reliability.
Thanks to the new stepper motor and to the MultiFunction software, PRISMA dosing pumps offer complete control overdosing speeds and working modes as well as great flexibility, meeting even extremely complex application needs.
PRISMA also boasts Level control, Alarms and Stand-by, while available working modes include Constant, Constant withexternal input, ppm, %, mlq, Pause-work, Weekly, mA, Pulse, Volt, external Batch and manual Batch.
Info Colour Screen
PRISMA dosing pumps feature the Encoder control knob for quicklybrowsing through the menus and a large display to easily regulate andcontrol working parameters. By changing background colors the backlightdisplay can also signal different working status: pump running (green);stand-by (white); warning condition (yellow); alarm condition (red).
Turndown
PRISMA stepper motor-driven pumps give you themost accurate control over the stroke speed, providingan outstanding turndown ratio of up to 4800:1. Itmeans PRISMA can split up the dosing process intoa maximum of 4800 steps in order to offer the mosthomogeneous and precise distribution of the productto dose according to the required application.
Slow Mode
Extreme versatility of PRISMA dosing pumps is alsodue to Slow Mode function. With Slow Mode enabledyou can reduce the suction speed to 75, 50 or 25% ofthe normal speed, making easier and more reliable thepriming and the dosing even when you have to workwith particularly viscous liquids.
All metering pumps flow rates are referred to 230 VAC
(50-60Hz) and 115 VAC (50-60Hz) mains.
For other power supply (24 VDC/VAC and 12 VDC) please enquire.

Tank low level stops the pump.
FLOW SENSOR INPUT
Flow sensor input SEFL (sensore di flusso) for dosing system control.
STAND-BY INPUT
pump enabling/disabling control
ALARM OUTPUT
Contact relay switched by pump's anomalies
STROKE SPEED (FREQ.) ADJUSTMENT
Injection frequency control
STROKE LENGTH ADJUSTMENT
Injection volume control
DIGITAL SIGNAL
