SIHI SuperNova Pump ZHN – Hot Water
The SIHI SuperNova Pump ZHN is a range of horizontal, single-stage volute casing pumps designed for hot water circulation. Built to meet the EN 733 / DIN 24255 standards, these pumps offer easy replacement for obsolete or unreliable units. The ZHN series is engineered for the efficient handling of hot water up to 180°C without the need for cooling. The back pull-out design allows for the removal of the entire bearing unit towards the drive end without removing the pump casing from the pipework, making maintenance straightforward. A standard spacer coupling eliminates the need for re-alignment during servicing.
Primarily used in energy production, heat transport, and various industrial applications, these pumps are ideal for systems where hot water, despite its high system pressure, is preferred over oil as a heat carrier.
