EH-E series

Product catalog summary
Overview: The EH-E series electromagnetic metering pumps combine advanced pump and electronics technology, offering compact design and a maximum flow rate of 1.25 L/min. These pumps are equipped with a microcomputer controller for versatile operation modes.
Specifications: The pumps feature adjustable stroke length (20%-100%) and stroke rate (0-360 spm), allowing for a wide range of flow rates. The pump body is made from reinforced plastics with a water- and dust-proof structure (IP65 rating). The pump head materials include PVC, GFRPP, PVDF, and SUS, with other wetted parts made from corrosion-resistant materials like Hastelloy C276 and PTFE.
Controller Functions: The built-in microcomputer controller supports four operation modes: manual, proportional control, pulse control, and count control. The controller allows for easy switching between modes using keys and can handle various input signals (DC0-20mA, pulse signals).
Performance and Safety: The EH-E series pumps have a maximum discharge pressure of up to 1.0 MPa and can operate within an ambient temperature range of 0-40°C. The pumps are designed to prevent over-feeding by maintaining a minimum discharge pressure and using optional check or back pressure valves.
Dimensions and Power: The pumps are available in different models (E31, E36, E46, E56) with varying capacities and dimensions. They operate on single-phase power supply (AC100-240V) with an average power consumption of 48W.
Additional Information: The document includes contact information for IWAKI offices worldwide and notes on export control regulations. Users are advised to read the instruction manual carefully for safe operation.

High-tech combination of pump technology and electronics technology Electromagnetic Metering Pump EH Series features not only compact, but also can achieve a maximum flow rate of 1.25 L/min. The EH-E pump's controller includes a microcomputer that enables a single pump to provide not only manual operations, but also automatically controlled operations based on various input signals (current and pulse signals). High resolution The discharge volume is adjusted in terms of stroke length and rate. The stroke length can be adjusted between 20% and 100%, and the stroke rate can be set between 0 and...

EH-E series-3

EH-E series Model for high flow and industrial process Functions of the controller Manual mode Count-control mode Stroke rate can be increased or decreased by 1-spm anywhere within the range 0 to 360 spm, and is able to set either during operation or stop. The EH-E pump performs count-control operations in response to external pulse signals. The pump provides (n) times shots per pulse input. Set the number (n) between 1 and 999 by means of the keys. If next pulse is input before a set number of shots have been completed, the pump is capable of storing that pulse signal (max. 255 pulses). It is...
