NOTE: Make sure any seal leakage is disposed of properly.
WARNING
Since leakage or seal failure can be expected to eventually occur, be sure installation
can withstand this situation. Take appropriate measures if liquid is hazardous.
F.7 SPARE PARTS
Where pump out-of-service time is of vital concern, and this down time must be minimized, a
set of spare parts or repair kits should be retained on-site.
F.8 DISASSEMBLY AND REASSEMBLY
Various procedures for disassembly and reassembly apply to different pumps. Refer to the
specific pump instruction manual on how to perform these procedures.
G. FIELD AND FACTORY SERVICE AND PARTS
Imo Pump maintains a staff of trained service personnel that can provide pump installation, pump
start-up, maintenance/overhaul and troubleshooting supervision as well as installation and
maintenance training.
Our factories provide maintenance as well as overhaul and test facilities in the event the user prefers
to return pumps for inspection or overhaul. Pumps that have been factory-overhauled are normally
tested and warranted “as-new” for a period of one year from date of shipment.
For either field service or factory overhaul assistance, contact your local Imo Sales Office or
representative at the Technical/Customer Service Department in Monroe, NC, USA.
Most pumps have repair kits available. Minor Repair Kits are used to repair leaking seals, bad
bearings and/or for re-assembly after pump tear-down. They include (as applicable) pump shaft
seals, packing, all gaskets/O-rings and bearings. Major Repair Kits are sufficient to rebuild
completely worn-out pumps to “as-new” condition. They include all parts found in Minor Repair Kits
plus all major internal parts subject to wear. Since kits have all the necessary parts, it is preferred
that they be purchased rather than selecting individual parts. When parts are individually selected
from the Parts List, some needed components are often overlooked. In addition, mixing worn or used
parts with new parts risks rapid wear and shortened service life from the new parts.
