Features of HRP series

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

The HRP series is powered by 12VDC or 24VDC 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 0-720spm. The minimum flow of 0.055mL 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 720spm, even if the external signal input instructs the pump to run beyond that speed.

1-5V control type

The input of 1-5V proportionally controls the pump operation (stroke rate).
• An input signal is required to enable operation in addition to power activation for this type.

4-20mA control type

The input of 4-20mA 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 720spm 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 720spm. The flow rate increases as a discharge pressure decreases.
• 0.12MPa 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 – 40 ºC   • Allowable liquid temperature: 0 – 40 ºC   • Allowable voltage deviation: ±5% of the rated voltage  12VDC: 11.4V – 12.6V, 24VDC: 22.8V – 25.2V
