Premium Vacuum Pumps and Blowers

At Metallurgical High Vacuum (MHV), we’re committed to providing the highest quality vacuum pumps and blowers in the industry. Whether you’re looking for new or remanufactured equipment, our products exceed the rigorous standards of excellence expected in the industry.


Experience the exceptional performance of our MHV-manufactured rotary piston pumps. Crafted entirely within our state-of-the-art facility, these pumps exemplify our dedication to superior craftsmanship:

  • SD 300
  • HD 300
  • HS 430

SD 300

This is a 300 CFM adaptation of the Stokes 412H11 rotary piston pump.  It dimensionally interchanges with the Stokes model.  All castings for this pump are sourced from Midwest foundries and are machined in MHV’s facility.  Currently there are 26 of these pumps operating in daily service.

HD 300

This modification adds full pressure lubrication to all internal parts of the rotary piston pump.  The oil pump is driven by the pump mainshaft.  There are particulate and acid filtration spin-on oil filters with particle ratings down to half micron.  Failsafe lubrication is standard and allows lubrication in the event of pump failure.  Atmospheric pressure will push lube oil into the pump under this condition.  There is an hour meter and a delta P pressure readout to show pressure drop on the filters.  Currently there are four of these pumps in daily service.

HS 430

This modification increases pump RPM so that it nets 400 CFM at the pump inlet.  Full pressure lubrication is identical to that of the HD 300 pump.  There are particulate and acid filtration spin-on oil filters with particle ratings down to half micron.  As with the HD 300, the HS 430 pump has drilled hinge bars that funnel oil into the critical hinge bar/piston slide tang area.  There is an hour meter and delta P metering on the filters identical to the HD 300.  A 20 HP Baldor “XE” TEFC motor is installed to dower the pump at the increased RPM.  This motor will run at 20 hertz using a variable frequency drive (VFD) without overheating.  This mode of operation greatly reduces energy consumption.  Currently there are 30 of these pumps in daily service with combined run hours exceeding one million.

Pump Sentinel

This is an add-on feature for HD 300 and HS 430 rotary piston pumps.  It includes the following:

  • Lube pressure sensor
  • Delta P sensor
  • Hour meter
  • Flywheel proximity sensor
  • Oil level sensor
  • On board PLC with internet communication protocol
  • Pilot lamps to warn of low oil level, low oil pressure, broken belts, high oil temp
  • Oil temp sensor

This modification package can be added to any 412H11 or 412J14.  Currently there are seven Stokes 412 rotary piston pumps with this modification currently in service.


Important note: The full pressure lube/failsafe lube option can be applied to any client’s 412H11 or 412J14 pump being remanufactured.  Currently there are 27 412H11’s in service with this modification.
