Mechanical Vacuum Booster pump

Mechanical Vacuum Booster pump

The RD pumps are positive displacement roots vacuum pumps. The pump bearings, gears and seals are lubricated by oil fed from oil reservoirs at either ends of the roots pump. A series of seals stops the oil from reaching the vacuum side of the pump. Roots pumps helps in shifting the operating pressure to a high vacuum range due to rotation of gear timed rotors in opposite directions. Roots vacuum pumps are capable of improving the attainable ultimate pressure of a pump system by a factor of 10.
