Drum Hub Infinite Rotation

Bushing bearing, stainless steel interior, steel exterior.

The Drum Hub (Endless Rotation) is a 360° continuously rotating swivel/rotary union fitting that allows the hose drum to rotate without interrupting the water flow in sewer cleaning and high-pressure water jet systems. It prevents kinking, twisting, and torsional damage to the hose during drum winding and unwinding, thus extending hose life and helping to maintain stable flow. It is a critical component for performance and safety, especially in professional systems such as sewer cleaning machines, drain cleaning machines, and mobile jetting units .

Technically, the drum hub operates with bearing/sediment housing and sealing elements inside the housing. While the central connection remains stationary, the outer housing rotates with the drum; this ensures a continuous and controlled rotational movement, reducing the risk of leaks in the high-pressure line. With the correct material and seal selection, it exhibits resistance to high pressure , sand and sediment erosion in the water, and demanding operating conditions.
