You can limit the maximum displacement in either direction.
1. Loosen the lock nut (F212) while holding the adjusting screw (F213) steady.
2. Rotate the adjusting screw some amount (using information in the following table). Rotating the
adjusting screw clockwise decreases the maximum displacement of the pump while rotating the
adjusting screw counterclockwise increases the maximum displacement.

Caution
Take care in adjusting displacement limiters to avoid undesirable flow or speed conditions. Re-torque
lock nut (F212) after every adjustment to prevent an unexpected change in operating conditions and
to prevent external leakage during unit operation.
3. One turn of the adjusting screw changes the maximum displacement as shown in table below
4. After establishing the desired maximum displacement setting, torque the lock nut to the torque
shown in table below.
