Maximum Volume Stop
The Maximum Volume Stop (MVS) is an optional accessory to XD5. The MVS limits the maximum displacement of the
pump by limiting the maximum stroke from the Control Piston.
6.2.1
How to Adjust
If an XD5 unit includes the MVS option, it will be visible on the
Valve Plate, as illustrated in
. If a pump does not include
the MVS option, this port will simply be plugged.
To change the maximum displacement of the pump, loosen the
locknut, and turn the adjuster in or out to reach the desired
maximum displacement. Turning the adjuster in (clockwise) will
decrease maximum flow, and turning it out (counter-clockwise) will
increase maximum flow.
Adjuster:
3/8 in. External Hex, w/ 3/4 in. Lock Nut
Range:
60 to 98.4 cc [3.6 to 6.0 in
3
]
Rate:
4.1 cc [0.25 in
3
] per turn
A locknut is provided to lock the MVS Adjuster at the desired displacement. Machine vibrations can
cause rotation in the adjuster, which will change the displacement setting. Remember to tighten the
locknut to preserve the desired setting.
