Features of EHN-R series

High Resolution

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

Control Unit

The highly-functional EHN-YN which is equipped with digital and analogue input s are added to the standard production line as well as EHN-R.

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

Controller function (Basic type)

Manual operation

Pump run/stop and stroke rate setting (1 to 360 spm) can be done by keys. Stroke rate can be set either when pump is running or stopped.

EXT operation

Multiply (1 : n)
Pump makes multiply operation by external pulse signal. Pump makes “n” times shots against one pulse signal input. “n” can be set from 1 to 999. Pulses which came while operation are put in memory up to 64535 shots.

Dividing (n : 1)
Pump makes dividing operation by external pulse signal. Pump makes one shot against “n” times pulse input. “n” can be set from 1 to 999.

• If “n” is set at 1, pump makes synchronous operation. If pump is connected to optionally available EH controller, please use this function.

STOP function

Pump stops by external contact signal. Pump operates when stop signal input is released. This function enables pump ON/OFF control. This is convenient function when used in combination with level sensor.

• It is possible to operate pump while STOP signal comes in (Change over with keys). In this case, when pump is operated in EXT mode, pump operates synchronous with EXT signal input while STOP signal is coming in.
