Pfeiffer Duo 11 Vacuum Pump

Pfeiffer Duo 11 Rotary Vane Pump

Pfeiffer Duo 11 vacuum pump is a dual-stage high-performance rotary vane pump with a pumping speed of 9 m3/h at 50 Hz and 10.5 m3/h at 60 Hz. The Duo Series pumps have a rugged design for demanding industrial applications.

The Duo 11 pump is a rotary vane vacuum pump used primarily for all low and medium vacuum applications. It’s quiet, compact and well suited for a wide range of bench top applications. The Duo 11 is an oil-sealed rotary pump with 1-phase motor with various motor voltage options. Duo series pumps are available in standard version with a conventional seal or M version with wear proof drive and magnetic coupling.

REMANUFACTURED OR REBUILT PFEIFFER DUO 11 VACUUM PUMPS:

All pump rebuild prices include disassembly, inspection & cleaning. Replacement of seals, gasket, springs, o-rings & valves. Other parts replaced as required upon approval for an extra charge. Pumps are then tested & painted.
