What periodic checks can I perform to ensure that my FILAMATIC® bench-top filler continues to operate accurately and reliably?
The following assessments should be completed annually. The pump post and volume control bushings (found in the bearing sleeve housing assembly) should be checked for excessive wear. Any gap between the ID of a bushing and the underlying pump post or bearing sleeve that is more than 0.002″ (allowing the bushing to be moved up/down or side-to-side) will affect the filling accuracy of the system. When a gap of more than 0.002″ is found, the bearing sleeve housing assembly needs to be replaced. The operation of volume control(s) should be thoroughly evaluated. With all of the filling units removed from the filler, loosen the eccentric post nut on the volume control assembly. Then, turn the adjustment knob to cycle the volume control through its entire range of motion. If it binds at any point, the lead screw assembly may be rusted and some penetrating oil may be required to free it.
