Dry Vacuum pump"DU-3000" assembled on the frame

Dry Vacuum pump"DU-3000" assembled on a frame strong  of a dry rotary type with natural air cooling is designed to create a vacuum of vacuum necessary for the normal operation of the milking machine and productive milking of cows. A two-blade dry-rotary pump with a capacity of 0.75 kW and a shaft speed of 3000 rpm is installed on a convenient frame with wheels, retractable handle, receiver, vacuum meter and vacuum regulator. 

The vacuum unit strong of the milking machine consists of an electric motor and a dry rotary pump that is installed on the motor shaft without any couplings or pulleys. Such a structure of the milking machine makes it small and compact, but at the same time powerful and highly productive. It easily starts and runs in the cold season, and does not freeze, unlike oil-type pumps. 

Inside the vacuum pump there is a rotating rotor , inside which graphite vanes  move freely. During the rotation of the rotor blades move in grooves, changing the working volume in the chamber. During suction there is an increase in volume, which creates a vacuum between the blades, and with a decrease in the volume between them, the pressure increases, and the air escapes through the muffler.
