DSTI Designs Special Rotary Union for Severe-Duty Hydraulic Application


DSTI's latest design offers a unique solution for demanding hydraulic fluid applications. These rotary unions are 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 was designed to function as a direct replacement for the original OEM rotary union.

DSTI offers full custom rotary union design & build services. They can also design direct replacements for OEM unions. Please contact the sales department to discuss details.
