ROTARY VANE OIL LUBRICATED VACUUM PUMPS

VACUUM PUMPS
Simplicity of design with only one shaft and direct drive produces robust, long-lasting vacuum pumps with low maintenance and running costs. The vanes are sealed by the metered supply of oil. Already equipped with integrated non-return valves and an efficient oil separation system, these vacuum pumps can be fitted with other accessories without a problem.
The standard-featured circulating-oil lubrication System with integrated oil cooler and cover additionally minimise noise emission. Controlled by a float valve, the oil return suction system also makes these vacuum pumps suitable for use in rough-vacuum applications. Optional water cooling significantly prolongs the life of the oil, even in difficult ambient conditions.
