Stokes 412J Microvac Piston Pump, 230/460V, 3Ph, 260 CFM, 15 HP Pumping Speed, 900412014 / 900-412-014
Stokes Vacuum 412J Overview:
The Stokes Vacuum Microvac J Series Rotary Piston Pumps have over 80 years of industrial use. The Stokes J Series Pumps are piston oil design suitable for small floor space.
The Stokes 412 J piston pumps has set the new standardsfor providing extreme durability and pumping performance.
The Stokes 412J Series operates on rotational speed which enables longest pump life cycle.
The Stokes 412J Oil Piston Pump offers the following features:
- Robust, long life and low speed rotation pump with less rotary sliding parts
- Efficient design provides maximum uptime with minimal moving parts and large clearance
- Low ultimate blank-off with maximum speed down to 1 Torr and continuous high pressure pumping up to 600 Torr
- Latest valve design virtually eliminates valve maintenance and reduces noise, while requiring lower power
- Complete and self-contained unit delivered ready to install
- Automatic lubrication system provides proper flow of oil to bearings and sealing surfaces and prevents backflow into system
- Gas ballast as standard
- Total capability includes the manufacturing and service capabilities to keep your equipment in top operation with a broad range of vacuum system accessories
- Space-saving design which saves up to 50% of valuable floor space
