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.
Metering and volumetric pumps EHE Series
– Control: Start / Stop (ON / OFF) – 4-20 mA – pulse input – Stop / Start externalSolenoid 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).SKU: n/a -

EZ Series 23.8 L / H @ 150 PSI
EZ series
solenoid metering pumps – Control: Start / Stop (ON / OFF)Electromagnetic Dosing Pumps – EZ Series
This economical version allows precise dosing at the lowest cost. Manual operation or simple on-off remote control for conventional liquid injections.
EZ pumps benefit from the major advantages of the range and bring precision and reliability.
Solenoid metering pump EZ – High frequency of injection
With its injection rate reaches 360 beats per minute dosage is more regular.Solenoid metering pump EZ – High accuracy
The accuracy of the flow rate is roughly 2%. Linearity is held within a range of plus or minus 3%. The frequency of injection is maintained at plus or minus 1%.Solenoid metering pump EZ – Compact
Ideal for integrators, pumps EZ series are small in size, lightweight and silent.Solenoid metering pump EZ – Double ball valve
The ball sets, seat and guide provide a complete seal and ensure the precision and good performance boot.Electromagnetic metering pump EZ – Long Membrane
The membrane, PTFE on EPDM is molded on a steel core. A membrane reinforcement minimizes flow variations if pressure changes.

Serie LK 431.5 L/H @ 225 PSI
In a separate class – LK is a hydraulic diaphragm pump that can accommodate most electric motors.
Can easily add a variable speed controller.Dosing and metering pumps LK
– Control: Start / Stop (ON / OFF) – 4-20 mA – pulse input – Stop / Start externalDiaphragm and electromagnetic dosing and volumetric pumps
The electromechanical LK diaphragm dosing pumps feature a dual cam system which makes them very reliable, compact and robust.
Thanks to its extensive experience in this field, IWAKI Co has developed all its know-how to create an ideal dosing pump for the chemical industry, water treatment, paper and food industry.
The prime qualities of this type of pump are performance, ease of use and low maintenance cost.
The flow rate of this volumetric pump is 2%.
The reproducibility is perfect thanks to the linearity of the shots and its accuracy. There is no variation in the flow time.
It is possible to adapt different types of motorization, either mono or sort and add variable speed variator.
This makes this series one of the most versatile at the most competitive prices in the industry.

Series EWN-Y + flow meter EFS
The EWN-Y series electromagnetic metering pump combined with EFS flow sensor provides accurate real-time control and flow display.
Dosing and metering pumps EWN-Y Series + EFS
– Control: Start / Stop (ON / OFF) – 4-20 mA – pulse input – Stop / Start external – Flow Verification – alarm relayThe 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.
