Brand New 31NB-30020 Auxiliary Hydraulic Gear Pump for Hyundai R450LC-7, R480LC-9S, R500LC-7

   Thank you for choosing Sparkling Machinery. 
   The 31NB-30020 hydraulic gear pump is constructed with a high-strength aluminum/cast iron housing enclosing precision-matched intermeshing spur gears and high-pressure side-plate seals. Engineered to generate steady, pulseless oil flow under continuous heavy duty cycle demands, it ensures reliable operating pressure for pilot controls and auxiliary hydraulic loops. Replacing a worn or internal-bypassing gear pump restores sharp joystick/pedal pilot responsiveness and stops hydraulic function lag.
