During the last several issues of Vroom in which we dealt with water-cooling as interpreted for karts, we put a few models of pumps on the test bench. At this juncture, we would therefore like to take stock of the situation, directly comparing the various results. Not only that: we have also added pressure testing for all these pumps. In the photos you can also see the “sensor group” used, which includes the measurement of hydraulic pressure in the circuit and that of the amount of water passing by (flow meter). We’d like to point out that the system has been assembled in such a way as to guarantee an internal passage section that is always constant and equal to that of the pipes, so as not to interfere with the flow itself and with the relative measurements, which were carried out in collaboration with Officine in Progress and with the help of Andrea Saccucci.
