Turcon® Varilip® PDR

1 of 1 products in this brand
Turcon® Varilip® PDR is constructed from one or multiple Turcon® Polytetrafluoroethylene-based sealing elements, which are mechanically retained in a precision machined metal body, Turcon Varilip PDR (Performance, Durability, Reliability) rotary shaft seals provide positive dynamic sealing at high rotary speeds characterized by low friction and stick-slip-free running, the seal reduces temperature generation, permits higher peripheral speeds and lowers power consumption. Tests show that Turcon Varilip PDR requires only around 50 percent of the torque of a radial oil seal when running in Fomblin oil, commonly used in semiconductor vacuum pumps. This results in a long-service life, with maximized mean time between planned maintenance and greater productivity.
