Each repair begins with a deep understanding of client needs and a careful investigation into the root cause of failure. Technicians ask the right, leading questions, examine the full picture to deliver tailored, long-lasting solutions.
Demco ensures every rotating equipment is flawlessly balanced to the exacting G1 tolerance. Whether an electric motor, pump or generator over 50 HP or a component that’s undergone machining, the team mandates precision balancing to eliminate vibration and maximize reliability. It repairs almost all brands and types of pumps, including centrifugal, submersible, split case and diaphragm models. Specialists also handle large-scale fans up to 10 ft. in diameter, including industrial dryer fans. Demco’s upgraded computerized dynamic balancing underpins its capabilities, allowing it to balance client equipment more efficiently— up to 10,000 lbs.
In one instance, the team rebuilt an obsolete three-stage vertical turbine pump from the 1970s measuring over 32 feet in length by manufacturing new shafts, couplings, bearings, stuffing boxes, lantern rings and packing glands. It also partnered with a 3D-printing shop to remanufacture the damaged impellers. The outcome was a seamless restoration that returned the vintage workhorse to peak performance, saving the customer from having to invest in a completely new pump and motor.
Demco also took a standard 150 HP 444T 1800 RPM motor, rewound it to 75/37.5 HP at 1785/888 RPM, and replaced the shaft for an OEM application. This reduced the OEM’s estimated 18–22-week lead time to just two weeks. These real-world examples reflect not just Demco’s technical versatility but also its value in helping clients extend asset life and reduce capital spend.
Demco is embarking on a 9,000 sq. ft. facility expansion. The facility is slated to elevate lifting and crane capacities, ceiling height, and shop square footage by over 50 percent. This makes way for more advanced motor repair capabilities and accommodates a greater volume of work. As Demco prepares for the future, it remains laser-focused on the same promise that has earned it industry-wide respect: delivering precision-driven, in-house repairs that help clients keep moving, generation after generation.
