日本IWAKI易威奇膜片EH-E31(EH2105)
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 microcomputerthat enables a single pump to provide not only manual operations,but also automatically controlled operations basedon various input signals (current and pulse signals).High-tech combination of pump technologyand electronics technologyHigh resolutionThe discharge volume is adjusted interms of stroke length and rate. Thestroke length can be adjusted between20% and 100%, and the stroke rate canbe set between 0 and 360 spm, whichenables the EH-E pump to provide a widerange of flow rates.Microcomputer built-incontrollerThe controller includes a microcomputerthat enables a single pump to operate infour modes (manual / proportionalcontrol / pulse control / count control),switching between modes by means ofthe keys.Water- and dust-proof structureThe pump body, aluminium die-castframe is molded by reinforced plastics(GFRPP), has a water- and dust-proofstructure that is immune to liquids andatmosphere corrosion. The water-prooflevel is IP65.Chemical resistance featuresMaterials available for the pump head arePVC, GFRPP (Polypropylene), PVDF(Fluororesin), and SUS (Stainless steel). Allother wetted-parts consist of corrosionproof materials; Hastelloy C276, ceramic,fluoroelastomer, PTFE, etc.
