EH-E Big Signal Solenoid Pump

Characteristic

Electromagnetic Metering Pump EH-E Series not only compact, but also can achieve a maximum flow rate of 1.25L/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 0-20 mA and pulse signals).

Wide Adjustment Range

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 360 spm, which enables the EH-E pump to provide a wide range of flow rates.

Wide Adjustment Range

The controller includes a microcomputer that enables a single pump to operate in four modes (manual / proportional control / pulse control / count control), switching between modes by the keys.

Water and Dust-proof Structure

The pump body, aluminium die-cast frame is molded by reinforced plastics (GFRPP), has a water- and dust-proof structure that is immune to liquids and atmosphere corrosion. The protection grade can reach IP65.

Chemical Resistance Features

Pump head materials are available for PVC, PVDF, and SS316. All other wetted-parts consist of corrosionproof materials; Hastelloy C276, ceramic, fluoroelastomer, PTFE, etc.

Functions

1. Manual 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.

   2. Proportional Control Mode

The stroke rate can be proportionally controlled based on external DC0-20mA signals. Select an input signal by the keys.

   3. Pulse Control Mode

The EH-E pump performs division control operations in response to external pulse signals. The pump provides one shot per (n) times pulse inputs. Set the number (n) between 1 and 999 by means of the keys.

   4. Count-control Mmode

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 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 selectable to store the pulses input.
