The curves show the pressure (m head) against flow (m3/h) for water at 20oC and for a pump operating at 2 pole speed (2900 rpm with a 50 Hz supply).

They therefore apply to any fluid which is similar to water and has a viscosity of 1 cP and a specific gravity of 1.

For Air Separator 'AS' pumps and flooded suction pumps operating at other speeds, viscosities and specific gravities please contact MDM

Curves are approximate and are subject to change without notice.
