GRACO 557822 - Miniature Meter -FloGear Pump Only, 1 to 8 cu in/min (16 to 131 cc/min), 1500 PSI
GRACO Miniature MeterFlo Gear Pump designed for precise low-flow metering applications from 1 to 8 cubic inches per minute. This pump-only unit provides accurate fluid delivery for systems requiring controlled dispensing and metering capabilities.
Designed for use with virtually any type of Series Progressive or Single Line Resistive oil lubrication system. The Miniature Meter-Flo has a rugged steel reservoir and motor assembly withstands the toughest applications.
Capable of high volumetric output operating continuously at pressures up to 1,000 PSI (69 bar)
Compact with several options to create a complete system using feedback and control
Nominal displacements of 1-8 cu. in./min. (16-229 cc/mm.)
An adjustable internal relief protects pump from excessive pressures. Factory set at 1,000 PSI (69 bar)
Pump only - no reservoir
Reservoir has a suction line strainer, return line port, visual level gauge, pressure gauge and filler/strainer with spring return cap
Options include low level switch, high pressure indicator, and lube cycle timer
