Master Machine was established in 1980. We take pride in all of our work which is backed by a satisfaction guarantee.  Our staff is on call 24 hours a day, with pickup and delivery services available.

We specialize in rebuilding thick stock pumps for pulp and paper mills across the United States.  We recondition Impco and Warren pumps to original OEM specifications.  In many cases we have an Impco or Warren pump already rebuilt and ready to exchange for your pump reduce down time!  You will get your pump back with housing bores machined or ground.  We check rotors and shafts for cracks and either replace or repair (by machining and welding) them.  We supply and install NCB packing sleeves for longer life and greater serviceability.  From teardown and technical analysis through the final test run, all work is done in our shops, using our time-tested procedures.

When you need quality the first time, day or night, look no further than Master Machine Inc.
