The request: a vertical pipeline pump for clear water from 0 to 90 °C, 25 m³/h at 30 m, NPSH 3.5 m. It is a typical building supply duty, and the ISG65-160 covers it.
| Requested | ISG65-160 | |
|---|---|---|
| Flow | 25 m³/h | 25 m³/h rated |
| Head | 30 m | 32 m rated |
| Motor | 4 kW, 2900 r/min | |
| NPSHr | 3.5 m allowed | 2.5 m |
| Efficiency | 63% |
The pump gives 32 m at 25 m³/h and keeps delivering more flow at lower head. A margin of a couple of metres covers pipe ageing and small errors in the head estimate without oversizing the motor.
Clear water up to 90 °C is close to the hot water range. For a loop that runs hot all the time, the IRG version with a hot water seal is the better choice.
