Compact electromagnetic metering pumps HRP series (OEM only)

Features of HRP series

DC Power Voltage / Vertically- Or Horizontally- Oriented Pump Head

The HRP series is powered by 12 VDC or 24 VDC and offers an ideal fit for built-in applications. Select vertically- or horizontally- oriented pump head to get optimum mounting position in various host machines.

High Resolution

Digitally-controlled spm range is 0 – 720 spm. The minimum flow of 0.055 mL per shot offers a constant micro-injection

* The stop control type does not allow variable control of the number of strokes.

Waterproof and Dustproof Structure

The sealed drive unit and control unit are enclosed to a water/dust-proof rating of IP65.

* This pump is not completely water proof. Protect the pump with a cover when installing it out of doors.

Operational function

HRP pumps are controlled by an external signal and are available in the following types.

Pulse control type

A pulse signal input controls pump operation (stroke rate). The pump makes one shot per pulse synchronously.

• An input signal is required to enable operation in addition to power activation for this type.
• The pump can not exceed a maximum of 720 spm, even if the external signal input instructs the pump to run beyond that speed.

1 – 5 V control type

The input of 1 – 5 V proportionally controls the pump operation (stroke rate).

• An input signal is required to enable operation in addition to power activation for this type.

4 – 20 mA control type

The input of 4 – 20 mA proportionally controls the pump operation (stroke rate).

• An input signal is required to enable operation in addition to power activation for this type.

Stop control type

The input of the stop signal suspends the pump operation.

• The pump starts to run at 720 spm upon power activation for this type.
