Improvements in the double pumps for the transfer of liquids, characterized by comprising the arrangement of a main body carrying an alternative double crankshaft and connecting rod opposite and coplanar, whose pistons slide inside the two cylinders mounted on the main body and equipped with grooves for the entry and exit of the oil comprised therein, said pistons acting on fixed intermediate membranes by their edges between said cylinder and the corresponding cylinder heads, which are carriers of the liquid inlet and outlet valves and also of an automatic safety valve that can be manually operated to decompress the liquid circuit.
