Product Overview

ZW65-65-25 tops the DN65 group: 65 m³/h at 25 m on 11 kW at 2900 r/min. Here is the whole group for comparison.

Model	Flow (m³/h)	Head (m)	Power (kW)	Speed (r/min)	Inlet / outlet (mm)
ZW65-30-18	30	18	4	1450	65 / 65
ZW65-25-30	25	30	5.5	2900	65 / 65
ZW65-25-40	25	40	7.5	2900	65 / 65
ZW65-40-25	40	25	7.5	1450	65 / 65
ZW65-65-25	65	25	11	2900	65 / 65

The same DN65 pipework covers flows from 25 to 65 m³/h. So if a site may need more water later, it can often move up to a larger ZW65 model without changing the pipes.

Its efficiency of 52 % is the best in the group. For 65 m³/h with a DN80 suction, see ZW80-65-25, which has the same hydraulics.
