Hydraulic Gear Pump

This external meshing hydraulic gear pump adopts precision ground gear pairs and die-cast aluminum alloy housing, equipped with standard 4-hole square mounting flange. It features compact lightweight structure, fast heat dissipation and low running noise. The rated working pressure is 21MPa with peak pressure up to 25MPa, supplying stable hydraulic oil for hydraulic power units, small lifting equipment, sanitation vehicles and agricultural machinery. Displacement, output shaft type, inlet/outlet thread and mounting flange can be customized as required. With merits of low internal leakage, wear resistance, contamination resistance and long service life

Hydraulic gear pump is the core power component of medium and small hydraulic systems. This external fixed displacement gear pump comes with standard square 4-hole flange and integrated die-cast aluminum housing, featuring outstanding heat dissipation and anti-deformation during long-hour operation. The precisely ground gears matched with wear-resistant composite bushings ensure uniform meshing clearance, greatly cutting internal leakage and running noise for stable performance. The universal square flange fits most mini hydraulic power packs on the market. Multiple output shafts including straight key and spline are optional, and oil port threads are adjustable for high interchangeability. It is widely used in DC hydraulic power units, vehicle lifts, garden machinery, waste trucks and machine tool lubrication systems.
