Abstract

Improvemnts in the manufacture of rotary pumps characterized by the body of the pump which houses the lobar type rotors comprising a plate of a generally flat formation having orifices for passage of the rotor drive shafts and a pressed out casing which rests against the said plate thus determining the lateral and frontal rotor enclosure, the attachment of the two components being mutually capable of disassembly and being provided with means of sealing in the area of coincidence of the plate and the enclosure casing.
