Our factories provide maintenance, overhaul and test facilities in event 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 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 necessary parts, it is preferred that they be purchased rather than selecting
individual parts. When parts are individually selected from 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 new parts.
