1) The values shown are valid for an absolute pressure (pabs) of 14.5 psi (1 bar) at the suction inlet S and when operated on mine-ral oil (with a specific mass of 7.36 lbs/gal (0.88 kg/L)). 2) By increase of the input pressure (pabs>14.5 psi / 1 bar) the rotational speeds can be increased to the max. admissible speeds nmax limit(speed limits) (see diagram page 8). 3) Δp = 4600 psi (315 bar)
