ABSTRACT:
A method of manufacturing a rotor for rotary fluid pumps comprising the steps of assembling a hollow cylindrical body and both side plates to a hollow rotor body, providing the hollow rotor body with a plurality of sockets each receiving a separately fabricated U-shaped vane-groove forming member, and inserting the U-shaped vane-groove forming members into the respective sockets to fix the same to the rotor body by brazing. The U-shaped vane-groove forming member is made from a suitable material as a vane groove itself and sufficiently finished independently from the rotor body.
