Why Choose the FORWATER MH-90S-1100?
It keeps a very flat pressure curve: still 41 m at 20 L/min and 36 m at 40 L/min. That makes it well suited to buildings where several outlets operate at the same time without a pressure collapse.
Frequently Asked Questions
What head is available at normal flow? 41 m at 20 L/min, 36 m at 40 L/min and 29 m at 60 L/min.
Is it self-priming? The MH range is a multistage centrifugal design intended for flooded suction or mains-fed installations; for suction lift from a tank, choose the JPM or PM series.
Does it include dry-run protection? Yes — water shortage protection is standard on the MH series.
