SP series vacuum pumps are single stage, direct driven, oil-sealed and air cooled. A rotor with three vanes is positioned inside the pump cylinder supported by two bearings. The pumps have a built-in gas ballast valve and one of the simplest and most reliable oil recirculating system. The oil is pumped into the stator from the oil reservoir for lubrication, sealing and cooling.
