Progressive Cavity Pump Rotor Rechroming
Restore worn progressive cavity pump rotors through inspection, stripping, weld repair, hard chrome plating and precision polishing. ACCA evaluates each used rotor before recommending refurbishment.
From Worn Rotor to Restored Surface
These rotor photographs show the condition of used progressive cavity pump rotors before and after refurbishment. The objective is to recover a serviceable rotor surface and specified finished diameter when the rotor is a suitable candidate for restoration.
Extend the Useful Life of a Serviceable Rotor
A worn rotor does not always require immediate replacement. When the rotor body and head remain suitable for refurbishment, rechroming can restore the working surface and return the rotor to a specified finished diameter.
ACCA begins with inspection and measurement. The rotor condition determines whether stripping, weld repair, replating and polishing are appropriate. This evaluation-first approach avoids treating every worn rotor as an identical repair.
PC Pump Rotor Rechroming Process
The repair sequence is determined by the rotor’s measured condition and the required finished dimensions.
Inspect & Measure
Assess the rotor body and rotor head and document wear before establishing the repair scope.
Strip Existing Coating
Remove the current chrome or alternate coating so the underlying rotor surface can be evaluated and prepared.
Repair Wear Areas
Weld repair is applied where appropriate to restore worn areas before final surface preparation.
Hard Chrome Plate
Apply chrome to rebuild the rotor working surface for the required finishing operation.
Precision Polish
Polish the plated rotor back to the specified finished diameter and surface condition.
Final Verification
Verify the completed rotor dimensions and finished surface against the established repair requirements.
Rotor Rechroming for Major Progressive Cavity Pump Platforms
ACCA can evaluate progressive cavity pump rotors used in a range of installed pump platforms. Manufacturer names are used to identify the equipment for which a rotor may be evaluated.

Request a Rotor Rechroming Evaluation
To begin an evaluation, provide as much identification and condition information as possible. Existing pump and rotor data help determine the correct dimensional and repair requirements.
Send Us Your Worn Rotor
Provide the pump model, rotor identification and condition information to begin a rotor refurbishment evaluation.
