in the pump housing, rotating at the identical speed in reverse directions to carry out
perform of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the conclude covers of the pump, rotating at higher pace and are stored at a
fastened relative situation by a pair of timing gears. The end clearance amongst rotors and
stop covers are fastened by adjustable metal shims in between the bearing housings and the
conclude cover at the fixed conclude, which assures one-course growth of the rotor when
temperature rises throughout its operation.
Four sets of inner seals (also recognized as piston ring) in the two end covers prevent lube oil
moving into into the pump housing. The shaft seal at the front-conclude include, also referred to as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to minimize temperature of the pump, all types of pumps (anticipate the two
smallest types) are outfitted with a gearbox cooler and entrance-stop include cooler.
Energy is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the driven shaft
