Electromagnetic metering pumps High resolution & ultra compact 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 verticallyor horizontally-oriented pump head to get optimum mounting position in various host machines. Waterproof and dustproof structure High resolution Digitally-controlled spm range is 0720spm. The minimum flow of 0.055ml per shot offers a constant imperceptible injection. 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. 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. • The pump can not exceed a maximum of 720spm, even if the external signal input instructs the pump to run beyond that speed. • 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. Optional air vent valves are available. ���������� ����� Stop control type The input of the stop signal suspends the pump operation. • The type of pump sta
