- Belt Drive Rotary Vane Vacuum Pump <SW> Series
Abundant achievements, high reliability and durability, and variety
Features
Reliable belt-driven rotary vane vacuum pumps have been mainstays since the founding of our company, and they remain so today. Since our first models, we have made many improvements in convenience, durability and safety. In contrast to direct-coupled models, the rotational speed for these models is set to 600min–1, using pulleys of different diameters and abundant lubrication. This series has established a reputation for durability and long life.
This product line offers models that cover the spectrum of pumping speeds, from 20 to 1500L/min, in single and double compression types, and in four styles(U/T/B/P).

Operating Precautions
Standard operating conditions
1. Kinds of suction gas: air or inert gas
2. Suction gas temperature: 10 to 40℃
3. Ambient temperature: 10 to 40℃ /Humidity 75% or less
Please consult with us before using products under the following conditions.
1. Pumping corrosive or combustible gas; chemicals, solvent , powders, or water vapor
2. Operating pressure of 1000Pa or higher
3. Fluctuating vacuum and atmospheric pressure
Periodically check pump oil for contamination and proper levels.
When turning off the pump, restore atmospheric pressure in the pump to prevent backflow.
A large amount of oil mist is generated in the pressure ranges between atmospheric pressure and approximately 133Pa. We recommend using an oil mist trap to prevent leakage.
