Abstract

PURPOSE: A geared motor pump having a simple structure and providing an easy operation which is suitable for handling special liquid having a high vapour pressures, which may provide a positive prevention of a leakage of the handling liquid and of a change of quality caused by an accumulation of the liquid.
CONSTITUTION: A geared motor pump is made such that the pump 10 and the motor 12 are connected with each other via adapter 14. In this case, auxiliary pump chamber 38 communicating with the rear rotor chamber 36 is arranged at a rear end of the rear rotor chamber 36 of the motor 12, and auxiliary impellar 40 fixed to one end of the motor rotor shaft 24 is arranged in the pump chamber 38. Discharge pipe 22 of the pump 10 and the auxiliary pump chamber 38 are communicated via circulation pipe 42, thereby a part of the pump processing liquid is guided to the auxiliary pump chamber 38, the processing liquid compressed by the auxiliary impellor 40 may be returned to the pump 10 via motor 12 and the liquid passage 48 of the adaptor 14.
