***60 days warranty***

The RC 5 is a four-stage vacuum pump consisting of an oil-sealed, two-stage rotary pump with a series connected two-stage diaphragm-pump. The two units are mounted on a common shaft and are connected directly to the drive motor. The dry-running compressor-type diaphragm pump permanently evacuates the oil reservoir of the rotary pump, thus considerably increasing the latters maximum vapour inlet pressure and chemical resistance.

With the gas ballast valve closed, the rotary vane pump shuts off vacuum-tight. This, in turn, prolongs the intervals between oil changes and improves corrosion resis-tance. The oil system incorporates an oil pump, this forced-lubrication system ensures an adequate supply of oil to the pump unit even at high inlet pressures. A mechanical retaining valve in the oil system prevents oil suck-back into the vacuum system.

The oil mist filter of the rotary vane pump removes 99% of the oil mist. If an exhaust waste vapour condenser is fitted (available on request), the vapours handled by the pump can be condensed to a large extent and either recycled or disposed off in accordance with regulations.
