Dsr50V Rotary Positive Displacement Roots Vacuum Pump

DSR50V Rotary Optimistic Displacement Roots Vacuum Pump

Solution Introduce

DICHENG DSR50V Rotary Positive Displacement Roots Vacuum Pump adopts the innovative engineering of Japan,
its air capacity is 0.86m3/min – 2.46m3/min,
the negative pressure is from -9.8Kpa to -49Kpa. 

The major characteristic of our air blower is little volume, gentle excess weight, circulation sturdy, sound modest, steadily dependable procedure.

Solution Characteristic

one. Air movement and pressure can be personalized
two. Stable air stream and much less pressure variation
3. Clean air not with oil moist
4. Development easy and easy routine maintenance
five. Bearing are all lubricated by oil moist
six. Prolonged support daily life

Description of Performance parameters
The performance parameters table exhibits the design, outlet diameter, rotate velocity, discharge pressure, air capability and power of motor.

one. The air capacity and strain in the tables is in normal suction condition. The normal suction condition is 20ºC temperature, one.033 kgf/cm2(a hundred and one.3Kpa) Common atmospheric strain and 65% relative humidity.

two. The air capability and strain assortment of some blower versions is repeated, to make sure the support existence and low sounds, should use the greater design.
