Preventative Maintenance - Pump Paint Packings
Check daily to ensure that there is the correct type of lubricant material present in
the solvent cup; this should be compatible with the material being pumped.
Confirmation from the material supplier should be sought to ensure compatibility to
prevent the risk of contamination.
A universal lubricant is available - Wet Sol ‘Plus’ Binks Part Number 863009
Check daily for excessive material leaks into the solvent cup.
Upper Packing Adjustment
1. Stop the Pump and isolate the air motor air supply.
2. Relieve all fluid pressure from the pump.
3. Clean the solvent cup to remove excess leaked material.
4. Use the ‘C’ spanner to tighten the packing nut (22) and preload the chevron
packing , approximate torque 50Nm
5. Add a compatible lubricant to the solvent cup of the packing nut (22).
Upper Packing Replacement
1. Stop the Pump at the bottom stroke position.
2. Relieve all fluid pressure from the pump.
3. Disconnect fluid section to air motor coupling.
4. Carefully Start the air motor with reduced air pressure and stop at the top stoke
position. Isolate the air supply to the air motor.
5. Use ‘C’ spanners to remove the packing nut (22) from the upper housing.
6. Remove all parts and clean using compatible solvent, discard the 8 off chevron
packings.
7. Refit packing female retainer (40) into packing nut (22). Lubricate the bore with
compatible grease and fit 8 off new chevron packings (41&43) then fit the
packing male retainer (42).
8. Lubricate the thread of the packing nut (22) with compatible grease and fit into
the upper housing (18), hand tighten only.
9. Use the ‘C’ spanner to tighten the packing nut (22) and preload the chevron
packing, approximate torque 50Nm.
10. Refit the solvent cup.
11. Carefully drive the air motor shaft down towards the fluid section.
12. Couple the air motor to the fluid section.
13. Run the pump at pressure then de-pressurise again, retighten packing nut (22).
