MP PUMP REMOVAL AND INSTALLATION OF MECHANICAL SEAL or MOTOR
MECHANICAL SEAL
1 . Turn off power, lock out machine and remove stainless steel covers in pump area.
2. Remove (4) 5/16-18 hex nuts from Impeller housing.
3. Remove housing from pump-pack assembly.
4. The impeller will now be visible, take care to NOT place anything in impeller vanes. This will
cause damage to the vane and will not be covered under warranty.
5. Loosen 2 bolts holding drive sleeve to motor shaft.
6. Remove impeller with drive sleeve as an assembly, mechanical seal should come off with
drive sleeve.
7. Replace mechanical seal. Install with raised carbon face towards motor. Take care to install
straight onto sleeve. Install ceramic disc into adapter seat bore with polished side up. Take
extreme caution to not damage polished side as this will cause immediate leaks. Ensure seal is
seated to bottom of adapter seat bore. If needed use a wooden dowel and gently tap into place
to ensure tight seat into bore.
8. Replace impeller assembly back onto motor shaft. Use a light coating of anti-seize on motor
shaft to ensure smooth seating.
9. Push down onto impeller head using a gloved hand to reach a gap of .030” between the
bottom of impeller to top of adapter.
10. Tighten sleeve clamp while maintaining .030” clearance between impeller and housing.
11. Check rotation of impeller to ensure proper seating and gap clearance.
12. If rotation and clearance are ok, then replace housing to adapter.
13. Install (4) 5/16-18 nuts and lock-washers onto studs and tighten to 15-ft.lbs.
14. Verify that impeller does NOT hit or scrape pump housing.
