The Stokes 412H vacuum pump is an oil-sealed rotary piston pump used for industrial roughing vacuum applications. A reliable and efficient single stage vacuum pump, the Stokes Microvac 412H has a nominal displacement of 300 cfm, a pump speed of 490 RPM and an ultimate pressure of 2.5 x 10 -2 Torr.
The Stokes 412H vacuum pump is a rotary piston pump with a 3 phase 10 hp motor. It operates at a 83 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 412H 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.
