Features of EH-E series
Large Capacity
EH-E series is available in models with a max. discharge capacity of 340 – 1250 mL/min. Combined with the IWAKI EHN and EWN series, it can further widen a range of flow capacity.
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 1 and 360 spm, which enables the fine adjustment of discharge capacity.
Pump Head Variation
Materials available for the pump head are PVC, GFRPP (Polypropylene), PVDF (Fluororesin), and SUS (Stainless steel).
Water / Dust – Proof
The sealed drive unit and control unit assure IP65.
• The pump is not completely water-proof. Protect the pump with a cover when installing it outdoors.
Functions of Controller
The controller features a control mode based on analog input (0 – 20 mADC) and digital input (Pulse) as standard. The controlled operation can be performed in the control mode that best suits the purpose.
