The Crossover ball joint is a new dredge ball joint that provides optimal flow performance, its manufacturer VOSTA LMG said. Through computational fluid dynamics (CFD) the frictional losses and turbulence have been reduced.

Conventional dredge ball joints act like a ball valve when tilted, causing the flow area to reduce and frictional losses to increase. The patented Crossover design incorporates two wear liners which are shaped to provide full flow area in any tilted position. Additionally the two liners provide maximum wear protection for the ball, which no longer suffers from direct wear caused by the flow.

“Our customers typically select the Crossover ball joint for the considerable savings in fuel and other cost savings such as a reduction of wear,” said Marco Menheere, Product Manager at VOSTA LMG Components & Services. “Savings like these provide a very short return on investment and it becomes even more favorable when the reduced flow resistance results in higher production.”

“These deliveries are a milestone in the development of more efficient dredge ball joints and confirm the position of VOSTA LMG as innovative supplier of dredging technology,” said George Teheux, Manager Components & Services.
