ROTARY HIGH VACUUM PUMPS
 

This series of vacuum pumps are rotary sliding vane, oil immersed type. The rotor, stator and end covers are made up of high nickel content cast iron and are machined to very fine tolerance. These pumps are ideal for handling dry and clean air. Gas ballast and belt guard are provided as standard equipment.

FEATURES
• Exhaust valve is designed to eliminate "rapping" noise.
• Unique construction of the pump totally eliminates the sucking of air through the shaft seal.
• Pumps can also be operated with SAE-30 motor oil instead of vacuum oil
• Water Cooling Arrangement can be provided if required at extra cost.
