Stepper metering pumps

The WN series is distinguished by:

– optimized dosing capacity through the integration of an electronically controlled stepper motor. This allows real-time variation of rotation speed, and thus of dosage, in a range from 1% to 100%;

– ability to detect and manage electromechanical faults. The large backlit LCD screen and encoder knob allow for clear reading of data and easy navigation through menus, being able to quickly pogramm the system’s fuctioning modes, set alarms, and manage different outputs. The WNPHxx is also remotely controllable through the ERMES platform and the My Emec app.

The WN series includes:

WNPHxx, the compact all-in-one highest precision solution integrating a control instrument and two metering pumps

peristaltic stepper pumps in one product; WNPHxx-5, the compact all-in-one solution of highest precision that integrates a control instrument, a peristaltic stepper metering pump and a salt electrolysis output (max 5A).

PRISMA is a metering pump with a diaphragm stepper motor. The position and speed of the diaphragm are controlled by the microprocessor for the entire delivery/suction cycle.

PRISMA is equipped with Level Control, Alarms and Stand-by, while working modes include: Constant, Constant with external input, ppm, %, mlq, Pause-Work, Weekly, mA, Pulse, Volt, External Batch and Manual Batch. The included installation kit ensures the best and fastest installation.

Dual stepper motor technology combined with two long-life, low-permeability peristaltic tubes, ideal for maximum safety and precision in the dosing of biocides and inhibitors. The inverter function allows advanced chemical management in complete safety for the operator. The scheduled maintenance function minimises system downtime. Automatic water draining is managed based on the conductivity value detected, preventing the accumulation of dissolved salts and ensuring optimal chemical balance in the cooling water circuit.

Motor and accessories

• 2 stepper motors continuously adjustable between 1 and 25 rpm
• Long-life peristaltic tubes (TPV)

Power supply

100 to 240 VAC

Performance

The diaphragm version is an advanced solution for an extremely wide range of chemical dosing applications in evaporative towers thanks to its wide flow/pressure range. It is equipped with solenoid-operated diaphragm movement with hydraulic parts in PVDF with high chemical resistance. Integrated functions include manual or automatic bleed, standby mode, and delayed start of dosing.

Motor and accessories
