Device for pumping liquids with a diaphragm pump driven by a hydraulic circuit.

摘要

A DEVICE FOR PUMPING LIQUIDS, PARTICULARLY IN HEAT PUMPS, which consists of a diaphragm pump (10) driven by a hydraulic circuit formed by an oil tank (17), a rotary pump (18) placed between the tank (17) and a lower chamber (15) diaphragm pump (10) and a rotary distributor (19) whose function is to provide and sucking said oil moves swingably to said pump DIAPHRAGM (10) to thereby produce A SUPPLY ROCKING AND VACUUM liquid pumped flowing to the upper chamber (13) diaphragm pump (10).
