Product Description
Differentially pumped rotary platforms provide 360° of continuous rotary freedom through the wall of any vacuum system. The DPRF-series platforms have two stages of differential pumping isolated by fluorocarbon seals on precision sealing surfaces to provide base pressures in the 10-11 Torr range and will withstand bakeouts up to 210°C.
All DPRF-series platforms come with a fine adjust worm drive and 0.1° Vernier scale for easier and more accurate angle adjustment.
Both top and bottom flanges are tapped full depth for use with standard length flange hardware, and the integral half-nipple option is available for mounting to an existing tapped flange.
The DPRF-series platforms also have options available for motor drives and crossover pumping.
Please consult the factory with your customization needs.
