Stokes 146H Vacuum Pump

Stokes 146H 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 146H has a nominal displacement of 30 cfm and an ultimate pressure of 1 x 10 ^-2Torr.

The 146H Stokes vacuum pump is a rotary piston pump with a 3 phase 1.5 hp motor. It operates at a 71 dB(A) noise level. Adjustable gas ballast valves are standard equipment for handling water and other vapor loads.

REMANUFACTURED OR REBUILT STOKES 146H 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.
