The Edwards E2M18 is a free standing dual stage rotary vane pump that is designed for reliable, long-term operation.It is equipped with thermal overload device that prevents overheating (single phase only).Its drive is provided through a flexible coupling by a single-phase or three-phase (four pole) motor.The motors are totally enclosed and are cooled by the motor-cooling fan.The EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapor - has become the industry standard for laboratory applications.

Features:

• Easy to use controls.
• Pressure die cast oil box with integral oil seals prevents oil leaks.
• Gas ballast valve for large water vapor handling capacity.
• Externally approved to EN61010, CSA, C22.2 and UL61010.

• Damaged or worn parts are replaced
• All O-rings, seals, springs and vanes are replaced
• Oil system recharged
• Pump performance measured to NIST Standards
• Oil system drained
• Pump is cleaned and painted if needed
• Packaged for shipment

Each reconditioned vacuum pump comes with a 90-day warranty for parts and labor.
