Model 400 HPU (Hydraulic Power Unit)
Pressures Up to 3,000 psi (207 bar)
The SelectForm® Model 400 Hydraulic Power Unit is designed specifically to meet the power source needs for Airmo end forming tools. The Hydraulic Power Unit (HPU) is equipped with valves and circuitry to reliably operate hand-held and modular end forming tools. The standard Model 400 Hydraulic Power Unit is supplied with an integral oil to air heat exchanger for cooling the hydraulic fluid to provide a continuous duty cycle.
Airmo SelectForm® Hand-held or SelectForm® Modular Tooling produces expansions, reductions, beads, flares, and other shapes on the end of tubes. Tools can be mounted to the top of the hydraulic power unit using optional stand and clamps.
The Model 400 HPU is easy to operate. Simply insert the tube into the tool and actuate the electronically operated foot switch. The system cycles automatically, producing a finished form in 2 to 5 seconds. End forming tools can be quickly changed out with quick disconnect couplers.
The Model 400 HPU is manufactured to customer specifications. Systems can be dedicated and highly automated to a single fixed task or designed to handle a variety of applications.
