in the pump housing, rotating at the exact same speed in reverse directions to carry out
purpose of suction and discharge of gas. The two rotors are supported by rolling bearings
in the conclude addresses of the pump, rotating at large pace and are stored at a

finish addresses are mounted by adjustable metallic shims amongst the bearing housings and the
end cover at the fastened finish, which assures one-course enlargement of the rotor when

4 sets of internal seals (also acknowledged as piston ring) in the two end addresses avert lube oil
entering into the pump housing. The shaft seal at the entrance-finish protect, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In get to minimize temperature of the pump, all designs of pumps (count on the two
smallest versions) are equipped with a gearbox cooler and entrance-finish go over cooler.
