Make Rotorchrome Your Progressive Cavity Pump Rotor Repair and Hard Chrome Specialists.

Yes, we can refurbish your rotors for 50% of the original equipment manufacturer's cost. Seem too good to be true? It's not.

Rotors received for repair are measured along the flights and stripped of existing chrome. Once stripped they are measured with micrometers again. We weld and repair gouges and severe scoring and repair tops of flights that are undersize due to extreme wear. Pin holes that are elongated are welded and drilled, slots are welded and milled. The rotor is ground and polished to assure uniformity from top to bottom, and then chrome plated.

We plate .005 - .010 over specifications and then grind and polish the chrome back to manufacturer's specs. Generally, we charge $3.50 (US) per square inch of plated surface. We NEVER want to be above 50% or $3.50 per square inch of your new replacement cost, whichever is lowest.

Most importantly, the rotor you receive from us can be repaired and chrome plated repeatedly. We have many satisfied customers who have not bought new rotors since we started working for them.

Remember, we offer traffic discounts that save freight charges and WE pay the freight back to you.

Need a rotor smaller or oversized? We do that, too.
