Abstract
Improvements in circulation pumps, mainly for central heating, characterized by the fact that in the frame (5) of the pump is provided a step (10) that forms biphas between the input side of the fluid and the exit side of the turbine ("built-in" bippers), and that a double-acting valve (11) operated from the outside of the pump frame can occupy two positions: one in which it is in contact with a seat (4), located in the entrance of the turbine, and another in which it is in contact with a seat (14) provided at the entrance of a bipºs, while a second valve (15), also operated from the outside of the frame, cooperates with a seat ( 18) provided at the exit or ejection of the turbine.
