DualVee® Washdown Wheels

Pittsburg, CA  – - Bishop-Wisecarver Corporation announces its new patent pending washdown wheels, the latest addition to the company’s signature DualVee product line. Designed primarily to meet the extreme demands of food processing equipment linear motion applications, the washdown wheel significantly extends bearing life, and is interchangeable with standard vee wheels for ease of replacement.

Available in sizes 2 and 3, DualVee washdown wheels feature an all stainless steel construction, FDA approved grease, an outer shield, and inner seal for added protection from liquids and debris. The rubberized metallic shield acts as a momentary seal when subjected to a stream of high velocity washdown fluid. The fluid velocity causes the rubberized shield to deflect and conform to the metallic surface of the wheel, sealing against ingress of liquids. The inner seal provides the principal line of defense, ensuring that external fluids are kept out of the wheel while retaining the internal lubrication grease; both important factors affecting the life of the wheel. Once the stream is directed away from the wheel, the deflected shield returns to its original position, allowing any residual fluid that entered the zone between the shield and seal to drain out or be spun out by centrifugal force.
