The new EWN-Y electromagnetic metering pump combined with EFS flow sensor provides accurate real-time control and flow display.

The required flow rate is simply entered into the pump. Thanks to feedback from the EFS sensor, the pump constantly adjusts its speed to maintain the dosage even under changing conditions of pressure, temperature, viscosity, suction or discharge.
The EFS is mounted directly on the pump and allows the digital display of the dosage per minute or per hour without any calibration.

The EWN-Y allows the sending of a proportional signal 4-20mA of the dosage, as well as the display of the operating history such as the total volume injected and the volume of liquid consumed over time.

The EHE series have capacities up to 20 gallons per hour at 150 PSI. Combining performance and an adjustment ratio of 1800: 1, one of the most versatile pumps on the market today.

Solenoid metering pump
This new series of metering and volumetric pumps can achieve a rate of 1.25L / min and, thanks to the integrated microprocessor, to manage a wide variety of current signals or pulses.

Metering and volumetric pump EH E – High Resolution
The volume injected is adjusted by means of frequency (between O and 360 strokes) and stroke length (20 to 100%), which makes possible a wide range of flow rates.

Metering and volumetric pump EH E – Integrated Microprocessor
The controller includes a microprocessor that allows four operating modes (manual, proportional divider and multiplier).

Dosing and volumetric pump EH E – Controller functions

Manual

The injection rate is increased or decreased by one stroke / minute in the range from 0 to 360. This setting can be carried out either on or off.

Proportional
The injection rate can be controlled by a flow of continuous type, 4-20mA, 0-20mA, 20-4 mA, 20-0mA.

Divider
in response to (n) pulses, the metering pump makes an injection. The number of pulses to be received is set by the keys between 1 and 999.

Multiplier
In response to a pulse, the dosing pump performs (n) injections. The number of injections is set by the keys between 1 and 999. The pump is able to memorize the pulses which occur during the execution of the previous command (maximum 250 pulses).

The EH-HV series is specifically designed to handle high viscosity chemicals up to 20,000 cps. Equipped with springs and stainless steel balls.
