    Why use a thermodynamic pump testing system?

    Using our thermodynamic method remains the most accurate and powerful means of testing a pump. The portable system makes this easy to do in-situ, without compromise to safety or disruption to operations.

    By simply measuring temperature and pressure across the pump, our precision technology calculates the efficiency and head of the pump (to an impressive accuracy of up to 0.5%). Then, by measuring the power consumed by the motor, we can calculate flow rate.

    How the FREEFLOW portable works

    Where existing pipework fittings are installed, an experienced technician can complete a typical pump test in less than two hours. A range of test points are taken at different flow rates, across the operating range of the pump. This data is used to plot performance curves of the pump under test.
