Graco monark 231117 pneumatic/air ram/pump w/903958 reg
This is a used Graco Monark 23:1 Stationary Pneumatic Ram/Pump joined up with a Graco Mastic Fluid Regulator (903958). This pump features a 20 liter single post ram assembly with a regulated air ram plate. This pump assembly was removed from a known working environment. Cosmetically this pump is in good condition with adhesive residue on the unit from normal use. Air pressure (50 psi) was applied to the unit to ensure the functionality of the pump, valves, regulators and ram. We could not test the mastic output as we are not set up to do so. As the valve supplying pressure to the pump itself was opened the pump applied down pressure to the rod, but little movement was evident. While troubleshooting the issue it was noted that the lower unit was not cleaned/flushed properly and the adhesive set up. This unit will require cleaning. No further testing was done.
