Crane Repair Service in Action

A look at pump repair, rebuild, and field service work completed by Crane Engineering

Repair, Rebuild or Replace Your Pump-
Which Option Makes Sense?

The right decision depends on the pump’s condition, repair history, downtime, parts availability and expected service life. Crane Engineering helps evaluate the options and recommend the most practical path forward.

FACTOR REPAIR REBUILD REPLACE
Bearing failure, but shaft and housing are still within tolerance
Replace bearings, seals and correct alignment/lubrication issue - -
Mechanical seal failure caused by sleeve or shaft wear
Replace seal and worn sleeve if damage is localized Rebuild if shaft, bearings and other rotating components also show wear Replace if repair requires extensive obsolete parts
Impeller is worn, eroded or damaged
Repair or replace the impeller if the rest of the pump is sound Rebuild if wear rings, shaft, bearings and casing also need restoration Replace if hydraulic components are badly damaged or unavailable
Excessive internal clearances / worn wear rings
Replace wear rings if wear is limited Rebuild when multiple internal clearances need to be restored Replace if casing or major components cannot be restored economically
Bent or badly worn shaft
Replace shaft if other components remain serviceable Rebuild if shaft damage is accompanied by bearing, seal and impeller wear Replace if shaft and major rotating components are obsolete or unavailable
Casing erosion, corrosion or cracking
Localized repair may be possible if casing integrity and pressure requirements can be maintained. Rebuild if casing can be restored and internals remain serviceable Replace when casing integrity can no longer be reliably restored
Repeated vibration, seal and bearing failures
Repair only if a specific root cause is found and corrected Rebuild if accumulated internal wear is contributing to recurring failures Replace or resize if the pump no longer meets system requirements, after addressing underlying system issues.
Pump no longer produces required flow or head
Repair if performance loss is caused by a specific worn or damaged component. Rebuild if performance loss is due to widespread internal wear Replace if system duty has changed beyond the pump’s capability
Obsolete pump with limited parts availability
Repair only where parts can still be sourced or fabricated Rebuild if major components can still be restored Replace when parts availability or reliability makes continued repair impractical
Our engineers will recommend the most cost-effective option after inspecting your pump.

Pump Selection by Industry

Pump requirements vary by process, fluid characteristics, operating conditions and system demands. Crane Engineering helps identify the pump technologies best suited to each industry and application.
