The object of the development is an experimental installation with pulsed circulation of the coolant in the main circuit for its use as a hydraulic drive of a diaphragm pump used for pumping liquid in the secondary circuit, which increases the energy efficiency of the pump drive for small-scale energy facilities. An installation with pulsed circulation of the coolant with a diaphragm pump was developed, assembled and tested on the basis of a new design of the shock unit with a cam profile, which makes it possible to create an acceleration of the flow at the pump suction. As a result of the experiment, we obtained the dependence of the volume of the pumped liquid on the frequency of operation of the shock unit.
