The RUVAC WS and RUVAC WSU are Roots pumps driven by a canned motor.
The WSU types have a pressure balance line between the discharge and intake flanges.
The RUVAC WS and WSU are lubricated with mineral oil or perfluorized polyether (PFPE) in the case of the PFPE models. Apart from the lubricant the mineral oil and PFPE models are identical in type.
Only the RUVAC WS/WSU PFPE can be used for pumping greater than atmospheric concentrations of oxygen or very aggressive or hazardous gases.
