Capacity Control - Zero Adjustment - Acromet 3000 Series Manual

7.5 Capacity Control – Zero Adjustment
Individual capacity control is provided for each pump head by means of a
micrometer located directly behind the respective pump head.
Should it become necessary to reset the mechanism, the procedure is as follows:
7.5.1 With pump running, screw micrometer mechanism in until piston
movement is just stopped. This can be sensed when resistance to turning
becomes constant.
remove micrometer mechanism
NOTE On some units, oil level will be above micrometer and spillage
will occur on removal. Hence measures should be taken to catch
spillage or tilt pump forward to avoid spillage.
7.5.2 Clamp micrometer anvil in vice and holding the barrel to prevent rotation,
loosen the socket set screw located in rear of barrel. This set screw locks
the barrel to the anvil.
7.5.3 Now, holding the mounting flange to prevent it turning, rotate the barrel
until it reads zero.
7.5.4 Again hold barrel to prevent it rotating and retighten set screw.
7.5.5 Set micrometer at 100% and refit to pump.
CAUTION
All major mechanical repairs should be undertaken by Acromet's specialist
servicing workshop in Melbourne.
