H Series Pump
Fixed, Aluminum, Pressure-Loaded Gear Pump, 9.88 – 36.50 cc/rev Displacement.
Aluminum Pump H Series fixed displacement gear pump offers high performance and high power density due to its aluminum construction, making it an ideal selection for the Aerial, Agriculture, Construction, Forestry, Material Handling, and Turf Equipment markets. It is available as a standard pump, a pump with a primary circuit relief valve, or a pump with a priority flow divider valve.
Gear assemblies consist of one drive gear, shrink-fitted on a precision-ground and polished drive
shaft. This shaft extends beyond the pump to permit coupling to an external prime mover. The second gear, being the driven gear, is also shrink-fitted on a precision-ground and polished driven shaft. Retaining rings, which are installed in grooves provided on the shaft, ensure that the gears will not move axially, and a key keeps the drive gear from moving radially.
