* Without inlet screen.
** Value could be depend on controller type.
(1)
At nominal rotational speed, water temperature = 25 °C (M = cold ; MT = 65 °C).
(2)
With a low exhaust pressure, depends on external conditions (water temperature, water flow, ambient temperature).
(not applicable for air cooling version).
(3)
With ratio inlet pressure/exhaust pressure >100, max. throughput reduced.
(4)
ISO/F flange, better with CFF flange.
