INSTRUCTION
Hydraulic pumps used for the work equipment
hydraulic units on construction machinery are pressure
loaded type gear pumps. This gear pump could run
under 300kgf/§†(4,350psi) maximum.
The pressure loaded type gear pump is designed so
that the clearance between the gear and the side plate
can be automatically adjusted according to the delivery
pressure.
Therefore, the oil leakage from the side plate is less
than that in the case of the fixed side plate type under
a high discharge pressure. Consequently, No
significant reduction of the pump delivery occurs, even
when the pump is operated under pressure.
