The Stokes Microvac rotary piston pump has set the standard for performance, efficiency, reliability and repairability in the industry for over 80 years. The Stokes Microvac J series rotary piston pump has been improved, upgraded, and fine-tuned to deliver even better dependability and productivity combined with minimal maintenance and process downtime. The integral oil distribution system eliminates external pi ping and delivers leak-free operation in a stylised design. A stylised oil reservoir cover and side cover ‘O’ rings improve sealing to eliminate oil leakage. An integral gas ballast valve built into the side cover allows buick adaptation to automatic gas ballast. Stokes Microvac rotary piston pump can get peak pumping speed from 234 m3h-1 to 884 m3h-1 and ultimate vacuum to 3.3 x 10-2  mbar.
