OVI circulating pump

The OVI series circulating pumps are used mainly for water circulation in boiler systems in household central heating system. They are quipped with permanent magnet motors and a differential pressure regulator which automatically and continuously adjusts the pump’s performance to meet the actual needs of the system.
