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.

• This specification is based on pumping clean water at rated voltage.
• Flow rate is collected at the maximum discharge pressure and 720 spm. The flow rate increases as a discharge pressure decreases.
• 0.12 MPa or more discharge pressure is needed to prevent over feeding. If the discharge pressure is at or below the required MPa, install a check valve (option) or back pressure valve (option).
• Allowable ambient temperature: 0 – 40ºC
• Allowable liquid temperature: 0 – 40ºC
• Allowable voltage deviation: ±5% of the rated voltage  12 VDC: 11.4 V – 12.6 V, 24 VDC: 22.8 V – 25.2 V
