Activair.cz > Products > Vacuum pumps and vacuum stations > Rotary vane pumps > Two stage pump > Stokes Microvac > Stokes Microvac 412J
The Stokes Microvac rotary piston pump sets the standard for performance and reliability as the industries most efficient, space-saving design. The Stokes Microvac rotary piston pump has been improved, upgraded, and fine-tuned to deliver even better dependability and productivity combined with minimal maintenance and process downtime.
Features and Benefits
- Robust cast and ductile iron construction provides rugged reliable operation.
- Efficient design provides maximum uptime with minimal moving parts and large clearance.
- Low ultimate blank-off with pressures down to < 10-2 Torr.
- New valve design virtually eliminates valve maintenance and noise.
- Space saving design which saves up to 50 of valuable floor space.
- Complete and self-contained unit delivered ready to install.
- Automatic lubrication system provides proper flow of oil to bearings and sealing surfaces and prevents back flow into system.
- Controlled balancing reduces vibration to a practical minimum.
- Gas ballast as standard.
Applications
