DRF series roots vacuum pump is a technically mature vacuum pumping equipment, which help fore vacuum pump expand its working range under low inlet pressure condition after combing with fore vacuum pump.
System vacuum degree could be enhanced to one order of magnitude higher if equipping with roots vacuum pump. If with 2 stage roots vacuum pump, performance could be even higher.
A pair of rotors of roots pump doesn’t contact with each other while rotating in high speed mode, which means small size roots pump also can be with high pumping speed. Fore vacuum pump can pump large capacity air in low speed by selecting suitable roots pump, obviously reducing energy consumption comparing with single fore vacuum pump with same speed.
No oil in pump chamber of roots pump, no pollution on the pumped medium.
With transmission system adopting flexible hydraulic device - a kind of high-efficiency power transmission method, DRF series roots vacuum pump is with compact structure and superior characters as below:
|Nominal Pumping Speed||m3/h||300||540||750||1000||2200||3600|
|Nominal pumping Speed||L/S||83||150||208||278||611||1000|
|Ultimate total pressure||Pa||＜2||＜1|
|A end oil capacity||Liter||1.5||2.4||6.8|
|B end oil capacity||Liter||0.8||1.3||3.7|
|Sealing oil capacity||Liter||0.13||0.15|
|Cooling water connection||Inch||1/4"||3/8"|
