Rotary Union for Hydraulic Fluid Applications

Rotary Union is used to transfer hydraulic fluid to multiple stations on a rotary punch press machine. The hydraulic fluid experiences numerous pressure spikes each rotation, caused by the punching process. DSTI engineers designed a special rotary union with an integrated hydraulic accumulator to dampen the pressure spikes in the rotary union. The union is designed to function as a direct replacement for the original OEM rotary union.
