Metering Pump— 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.   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.
