The manufacturing of fluid power components is a $23.5 billion industry in the United States.1
The hydraulic pump market alone was valued at $9.78 billion in 2019 and is expected to grow to $12.59 billion by 2025.2 This projected growth will be fueled by infrastructure developments, industrial automation, and increased global construction.
With so many hydraulic pumps and other components on the market, and with the projected growth of this market segment, it is important for end-users to have a basic understanding of the hydraulic repair, rebuild and remanufacturing industry.
The following information was abstracted from an article written by P.K. Guha in Hydraulics & Pneumatics magazine.3 While the article was written in 2009, the concepts presented are still relevant today.
For those owners and their employees who lived through the Great Depression, repairing, rebuilding and remanufacturing machine components was standard practice. You didn’t throw away any part that could be salvaged and reused. Frequently, however, the repaired units didn’t perform the same as they did when they were in peak working order. That was problematic, especially for products requiring precision hydraulics.
As technology has advanced, so too, has the ability to expertly repair and rebuild hydraulic components. The focus has been on not only ensuring that the repaired unit performs like it did when it was new, but also making the it look like new. The era of “rag-tag” gluing, welding and fusing of components to operate “almost the same” as a new unit is long past. Repaired units that look and function like they did when they were new can be achieved by today’s experienced repair facilities and technicians.
While many original designers and manufactures should have provided guidance on which hydraulic components could be repaired and which should not, Vickers was the only major manufacturer who actually did produce such an engineering-oriented procedure manual. The fact that their competitors did not do so was unfortunate for the manufacturer as the repaired unit still carries the original manufacturer’s identity.
The emergence of the hydraulic repair, rebuild and manufacturing industry has been fueled by a number of factors. When equipment is within a warranty period, owners look to the original equipment manufacturer (OEM) for service, but when that warranty expires the OEMs may be unwilling or unable to service the machinery. Even trying to get original parts from the OEM may not be possible because of excessive delivery lead-times and high prices.
End users then seek out a cost-effective repair facility that is geographically close to their location to reduce down time, and one that can repair their hydraulic components quickly and accurately. Hydraulic product repair / rebuilding facilities have not only emerged because they meet those user needs but also because they can generally do so at significantly reduced costs in comparison to OEM costs.
In part two of this blog we will provide information on the three categories of hydraulic products — dynamic, intermittent-dynamic and static; the differences between repair, rebuilding and remanufacturing; and the role of aftermarket parts in the hydraulic products service industry.
