Drive for metering pump
January 6, 2004

An integrated DC motor and controller is available for small metering, dosing and transfer pumps from seepex. The 120 VAC powered controller provides current and internal circuitry for low-flow, run dry and high-pressure protection devices. The controller has an auto-off-manual switch, will accept a 4-20 ma process control signal and can have instruments connected to it with standard 5-pin electrical connectors. In manual operation, speed is controlled by a lockable, ten-turn potentiometer.
