The Stokes 148H vacuum pump is an oil-sealed rotary piston pump used for industrial roughing vacuum applications. They are reliable and efficient pumps. Stokes Microvac 148H vacuum pumps have a nominal displacement of 50 cfm and ultimate pressure of 1 x 10 -2 Torr.
The Stokes 148H vacuum pump is a rotary piston pump with a 3 phase 2 hp motor capable of 1800 RPM Sync. It operates at a 72 dB(A) noise level. Adjustable gas ballast valves are standard equipment for handling water and other vapor loads. It’s robust cast and ductile iron construction provides rugged, reliable operation.
REMANUFACTURED OR REBUILT STOKES 148H VACUUM PUMPS:
All 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.
