Uniflex P250 special test bench with integrated rotary feed-through

01 September, 2020

Many technical applications are so specific that there are no machines off-the-peg that fit the bill. In these cases, special solutions are needed while, ideally, also being competitive on price. For Uniflex, its ability to provide these types of solutions to the hose & fittings marketplace been the basis of steady growth for the company since it was first established 48 years ago: Its solutions are ideal for special jobs such as the patented slide bearing technology for lubrication-free hydraulic crimpers. So, when a customer asked for a test bench for rotating hydraulic connections which are, for instance, used in hose drums of telescopic cranes, in booms of excavators or logging grabs in forestry technology, it was clear to Uniflex that it would be able to face this challenge.


Through technical enhancements to the company’s proven P250 hydraulic test bench it was made possible to also test components while they are rotating. For this, it was necessary also to integrate a rotational drive and a rotary feed-through into the test bench. And during the functional test, it should be possible to lock the component to be tested hydraulically by means of a valve. Within the scope of this order, a test pressure of 500 bar was required, versions for test pressures up to 3000 bar are, however, also an option. In addition, the adjustment to customer-specific applications allows further complex tests, such as those involving rotary couplings, quick couplings or hydrostatic travel drives.

The P250’s Control C2 system was also adjusted to this individually customised special machine. However, this was no significant problem for the creative technicians at Uniflex. The company provided a two-year manufacturer`s warranty for this made-to-order special machine too.

Moreover, when proper maintenance and careful handling are ensured, the owners of Uniflex devices can enjoy decades of service life from their investments. Uniflex comments that its machines, with their rare need for repairs, not only stand for ‘The best Return on Investment’ but also for CO2-conscious investments.
