Wobbling piston (WOB-L) Pumps
These pumps have piston style actuation that efficiently converts rotary energy via the motor into linear piston motion. These pistons are sealed to the pump cylinder via a flanged disk cup. This arrangement eliminates the wobbling motion of the piston end. The pump cylinder & cup forms a mechanical guide and seal for the piston. These pistons run without any additional lubrication with low friction and are highly heat conductive.
