General Technical Specications
Displacement Limiter H1 pumps are designed with optional mechanical displacement (stroke) limiters factory
set to max. displacement.
The maximum displacement of the pump can be set independently for forward and
reverse using the two adjustment screws to mechanically limit the travel of the servo
piston down to 50 % displacement. Adjustment procedures are found in the H1 pumps
Service Manual.
Adjustments under operating conditions may cause leakage. The adjustment screw can
be completely removed from the threaded bore if backed out to far.
