Pumps for heating
The heating pumps are suitable for under pressure heating circuits, cold water and cooling circuits, water supply, pressure boosting and in general for any industry where it is needed to pump clear liquids without abrasive particles in suspension and chemically neutral.
- Pumps for heating with dry rotor and in-line execution L and LRS ranges with spiral housing and very robust and built in cast iron.
