Features of EHN-YN series

Pump Head Variation

Wide variety of standard pump head (VC/VH/PC/PH/PP/FC/SH), automatic air vent type (NAE) and high compression type (55 type).
*Refer to page 5 for details of NAE and 55.

High Resolution

Thanks to digitized controller, stroke speed can be adjusted by 1 spm step from 1 – 360 spm. Combined with stroke length adjustment, you can do the fine adjustment from very small flow to maximum flow rate.

Multi-Voltage Power Source

Multi-voltage power source from 100 – 240 VAC for all models. You are now free from worrying about power voltage.

Air Vent Valve

Standard pump head models (VC/VH/PC/ PH/PP) equip air vent valve. Air in the pump chamber can be easily released by turning knob.

Water/Dust-Proof

Each unit such as driving unit and control unit is sealed to make the pump IP66 equivalent water/dust-proof.
*Do not install pump outdoor.

Multi Hose Connection

The use of a new hose stopper eliminates a twist in tube connection.
*Except for the following
Wet-end material: FC type, SH type, Accessories: Check valve CS type, Controller: EHN-R/YN Flow Checker corresponding type, Backflow prevention valve, Back pressure valve, Flow checker, T-joint
