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.
Adjustments under operating conditions may cause leakage. The adjustment screw can be completely
removed from the threaded bore if backed out to far.
