Refurbished Stokes 615 Rotary Lobe Booster Pump
The Stokes 615 rotary lobe booster pump is well regarded as the workhorse of many industries, including Vacuum Heat Treating, Sintering, Vacuum Arc and Induction Melting, as well as many others. The Stokes 615 is ideal for larger chambers and systems due to its pumping capacity. This booster pump can be configured as either belt drive or direct drive, as well horizontal (Stokes 615-1) or vertical flow (Stokes 615-2).
More recent versions of the Stokes 615 include the integration of mechanical seals, high speed balanced lobes and water cooled bearing housings to enable running the booster at higher speeds without increasing its footprint. MHR/MVR types which have a single mechanical seal on the input shaft and can be run at 3600 RPM and can achieve 2600 CFM. For the same speeds plus the ability to isolate process gases in the swept volume, the 5HR and 5VR variants additionally feature internal mechanical seals and water cooled bearing housing to remove the additional heat generated.
Note: Other motor voltages available upon request.
