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. |

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.
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.
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 ambient
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.
• Allowable room 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

No-voltage contact or open collector Note1 |
Note1: The maximum applied voltage to the contact
is 12V at 5mA. When using a contact type relay, the minimum application
load should be 5mA or below.
Note2: The external pulse signal is entered to run the pump over the
upper limit spm, the signal is cancelled.
