U5 Series Rotary Vane Vacuum Pump Oil Lubricated
U5 Series Rotary Vane Vacuum Pumps 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 U5 Series Rotary Vane Vacuum Pumps, Oil-Lubricated can be fitted with other accessories without a problem.

U5 Series Rotary Vane Vacuum Pumps Application
The U5 Series Rotary Vane Vacuum Pumps is a standard-featured circulating-oil lubrication system with integrated oil cooler and cover additionally minimize 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.
Optional gas ballast valves prevent condensing vapors from contaminating the pump oil. The oil-water emulsion arising from contamination reduces the pump efficiency or leads to a failure. The valve permits a regulated amount of fresh air (the gas ballast) to flow into the pump‘s compression chamber. By mixing saturated intake air with unsaturated fresh air, condensing is suppressed.
The new generation of oil-lubricated rotary vane vacuum pump: U 4.300
The new size between U 4.250 and U 4.400.
U 4.300 – U 4.250: comparison and differences:
- realization of faster pump-down times
- realization –for example– of more packaging cycles per unit time
- as far as possible to keep up with the dimensions
- to keep up with the installed motor capacities of 5.5/6.3 kW respect. 7.5/8.6 kW (50/60 Hz)
- in general: rise in productivity of our customers machines and systems
- increased air flow
- decreased dead storage capacities
- no differentiation between versions SA/K and F/K; the only remaining pump is a version with a final pressure of
- axial lubrication of the rotor for a secured final pressure
- improved oil return suction at free air
- decreased pressure differential
- decreased power consumption
- improved noise level during cold start-up
