Horizontal, single-stage volute casing pumps with dimensions and nominal ratings to EN 733 / DIN 24255 in back pull out design. The series ZHN has especially designed for the trouble free handling of hot water up to 180 °C. The back pull out design permits the removal of the complete bearing unit towards the drive end without removing the pump casing from the pipe work. If a spacer coupling is installed it is also unnecessary to disconnect the motor. Applications: The volute pumps of the series ZHN are part of the overall programme heat transfer and circutation pumps. They are primarily used for circulation of hot water in closed pipe and vessel systems. Therefore their fields of application are the energy production, the heat transport industry and here mainly in systems where hot water as heat carrier is given preference, despite its high system pressure, over oil as heat carrier. Technical Data: Flow rate: up to 600 m³/h Head: up to 95 m Speed: max. 3,600 rpm Temperature: max. 180 °C Casing pressure: up to 16 bar Shaft seal: mechanical seal Material: nodular iron
