I have to buy a circulator pump for hot water (T max 80-90),
7-8 m head (lift), 1 m3/h flow, max power consumptio in the range 60-80 W. Duty cycle very heavy (I mean many hours of uninterrupted work). The price is not the most relevant aspect, I need sth reliable and durable.
Which firm would you recommend in general ? If you happen to know the specifications also : which models ?
Tnx in advance for any suggestion
