Dsr-V Long Service Life Roots Vacuum Pump Manufacturer with Ce Certificate

DSR-V Long Service Life Roots Vacuum Pump Manufacturer With Ce Certificate


DICHENG DSR-V Series Roots Vacuum Pump adopts the advanced technology of Japan,
itsair capacityis0.86m3/min-58.65m3/min,
the negativepressure is from -9.8Kpa to-49Kpa.
The main characteristic of our air blower is small volume, light weight, flow strong, noise small, steadily reliable operation.
1. Air flow and pressure can be customized
2. Stable air flow and less pressure variation
3. Clean air not with oil moist
4. Construction simple and easy maintenance
5. Bearing are all lubricated by oil moist
6. Long service life
The performance parameters table shows the model, outlet diameter, rotate speed, discharge pressure, air capacity and power of motor.1. The air capacity and pressure in the tables is in standard suction state. The standard suction state is 20ºC temperature, 1.033 kgf/cm2(101.3Kpa) Standard atmospheric pressure and 65% relative humidity.2. The air capacity and pressure range of some blower models is repeated, to ensure the service life and low noise, should use the larger model.Type of technologyPositive displacement blowersDesignNegative pressureAir capacity0.86 to 58.65 m³/minNegative Pressure-9.8 to -49KpaMediumAir, Neutral gasesConveyingOil-freeWeight70 - 860kgDischarge Diameter50 - 200mm(or customized)
