Direct Drive Rotary Vane Vacuum Pump <DW> Series

Standard direct drive pump having abundant achievements

Features

DW series incorporate Gaede-type rotaryvane pumps. This series pumps are direct-coupled oil-sealed rotary pumps using two-stage rotor compression.
The rotational speed for this type is higher than for belt-driven models, because motor rotation is transmitted directly to the pump.
DW series supply 7 types of 50 to 1300(60 to 1500)L/min from which customer can select models to meet specification.(60Hz)

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.
