Varian HS 602 Rotary Vacuum Pump with Varian Oil Filter (17.6cfm)

This Varian HS 602 pump has been rebuilt and is in good working order. It also includes a Varian 949-9392 oil mist filter. 

The Varian HS 602 dual stage rotary vane pump is oil sealed and driven by a single phase electric motor. The pump works with force-feed lubrication, provided by an auxiliary gear-pump driven by the rotor of the vacuum pump itself. This ensures proper lubrication even when pressures are close to atmospheric.

The entire Varian HS 602 pump functional block is immersed in the oil contained in the casing. The oil guarantees perfect sealing of the discharge valves, enters the pump to ensure lubrication and sealing of the parts inside, facilitates heat dissipation and reduces pump noise.

The Varian HS 602 pump is equipped with a special antisuckback device which automatically isolates the vacuum system when the pump stops. This avoids rises in pressure or oil flow in the vacuum system while air is allowed back into the stator chambers.
