The graphs in these paragraphs express the available head pressure (net of the losses inside the units) of the high pressure (HP) and
low pressure (LP) pumps available with these machine, both on the utility circuit and on the recovery circuit, in relation to water flow
rate. Refer to the “Use of glycol solutions” paragraph to assess the effect of glycol on the useful head provided by the pumps. Below are
the corrective coefficients to apply to the curves, calculated in pure water.
