GRACO 557818 - Trabon Meter-Flo Electric Gear Pump, 40 cu in/min (655 cc/min) @ 1725 rpm, NPT Ports, CCW
GRACO 557818 is a Trabon Meter-Flo electric gear pump that delivers 40 cu in/min (655 cc/min) at 1725 rpm (or 26 cu in/min at 1140 rpm) through 1/2" NPT ports, rotating counter-clockwise (CCW) when facing the pump shaft. With its solid cast-iron housing, these rugged gear pumps are designed for dependable operation in high-demand industrial lubrication applications and are driven by a direct-coupled 1/2 HP motor.
Direct-drive and smooth-running, the Meter-Flo is ideal for applications requiring continuous delivery of hydraulic or lube oils to series-progressive metering systems.
