Single-stage pump units in compact design with nominal performances as per EN 733. Suction and discharge orifices are arranged in line with each other for direct installation in the pipe work. Electric motor and pump do not have a common shaft, standard motors as per list are applied. The back pull out construction permits the dismounting of the complete pull-out unit without removing the pump casing out of the pipe work. The separate pump shaft and motor shaft connected by a plug-in coupling make possible to dismount resp. replace the motor without touching the pump.
Applications:
When developing the unit construction type volute pumps of series ZTI, the main objective has been to turn out a number of floor space saving, easy-installation types especially adapted to the circulation of mineral and synthetic heat carriers in primary, secondary and tertiary circuits. Besides these units can advantageously be used as main circulating pumps in heat exchangers of compact design where they, owing to their constructional features, offer brand-new possibilities to the plant manufacturer for the layout of a system.
