Highest hydrostatic power of a pump/motor/transmission that is given by the max. flow rate and the max. pressure (Figure E 1):
P E = Q max · p max = M 2 · 2πn 2.
On constant pumps and variable pumps with pressure controller the corner power is also the power to be installed. On variable pumps with power controller the system is always configured to remain below this power for commercial reasons.
