HRP compact DC driven metering pump is designed for OEM fluid injection applications. Digitally-controlled high resolution injection capability operating from 0 – 720 SPM with 0.055 cc/stroke offers consistent low volume injection capability. Its maintenance-free design with four external control options and availability in 12V or 24V DC configurations makes this an ideal OEM solution for dosing applications. The HRP Series offers four control options including pulsed input, 4-20 mA speed control, 1-5V DC speed control and stop/start for maximum integration flexibility into OEM systems. HRP pumps are available with 12V or 24V DC drives with flows ranging from 0 ml/min to 38 ml/m and pressures to 0.2 Mpa. The HRP design features pump end construction materials of PVDF with FKM gaskets, alumina ceramic valves and PTFE diaphragm for excellent chemical resistance and cost-effective handling of most fluids. The IP65 construction makes it dust and waterproof.
