Rotary shaft seals contribute to lower energy bills

29 January 2009

Trelleborg Sealing Solutions has launched its new Turcon Varilip PDR range. Ideal for high-speed rotating applications, the range has exceptional low-friction characteristics, reducing torque. This in turn cuts power consumption, which can contribute to lower equipment running costs and ultimately decreased energy bills.

Turcon Varilip PDR (Performance, Durability, Reliability) rotary shaft seals are constructed from one or multiple Turcon PTFE based sealing elements which are mechanically retained in a precision machined metal body. The metal body gives a robust static seal against the housing, preventing thermal cycling, while the Turcon sealing element provides positive dynamic sealing on the shaft, leading to excellent performance at high rotary speeds. Characterised by low friction and stick-slip-free running, the seal reduces temperature generation, permits higher peripheral speeds and lowers power consumption. This results in a long-service life, with maximised mean time between planned maintenance and greater productivity.

“Currently there is a big push by industry in general to reduce power consumption and our carbon footprint,” says Stuart Moares, product manager for Trelleborg Sealing Solutions. “Apart from showing responsibility for the environment, it has the benefit of lowering ever-increasing energy bills.”

Taking a specific example from the semiconductor sector, tests show that Turcon Varilip PDR requires only around 50% of the torque of a radial oil seal when running in Fomblin oil, commonly used in vacuum pumps. This meets designers’ objectives for lower power consumption, a critical success factor in this type of equipment.

Based on the substantial experience of Trelleborg Sealing Solutions in supply of custom-designed metal-bodied rotary shaft seals, the new range offers customers a wide choice of standard parts in various corrosion-resistant materials and lip geometries. These will meet the requirements of virtually any rotating applications in numerous industries including chemical processing, oil & gas, semiconductor, automotive, motor sport, marine, machine tools and power transmission. As no specific tooling is needed in manufacturing, they prove a very cost-effective option.
