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 imperceptible injection.
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 resistant. Protect the pump with a cover when installing it out of doors.
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.
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.
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 type of pump starts to run at 720spm upon power activation.

• 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
