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.
The pumping of hot water makes high demands on the pump design. Safe operation is influenced, to a high degree, by the mechanical seal. Therefore the parameters of pressure, temperature and sliding speed at the mechanical seal are optimised so that the service life is considerably increased.
