Volute Pumps for heat carrier oils up to bis 350 °C TECHNICAL DATA Delivery head: Casing pressure: Shaft sealing: Flange connections: mechanical seal, radial shaft seal ring clockwise, when seen from Volute pumps of the series ZTI in inline design have been developed as space saving and easy-to-install pumping units, especially for the circulation of mineral and synthetic heat carriers in In compact design they are also applicable successfully in heat transfer plants as main circulation pumps; for reasons of their constructional features they offer the plant manufacturer absolutely new possibilities for his plant conception. Single-stage pump units in compact design with nominal performances as per DIN 24255 / EN 733. Suction and discharge orifices are arranged in line with each other for direct installation in 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. The DIN 4754 specifications are complied with. At present, the programme comprises 9 pump sizes. Casing pressure: Intermediate values can be interpolated Please note: Technical rules and safety regulations. Casing pressure = inlet pressure + zero delivery head Permissible inlet pressure (system pressure) 5 bar. Permissible inlet pressure = permissible casing pressure at shaft Suction and discharge orifice arranged radially in line. The flanges correspond to DIN 2533/PN 16. Flange design drilled as per ANSI 150 is possible Code of this construction: A- A groove ball bearing acc. to DIN 625, grease lubricated for service life, a liquid surrounded step bearing in the pump. Code Clockwise when seen from drive on the pump. Shaft sealing: Code 002: several radial shaft seal rings arranged in se- ries, uncooled Code CDC: unbalanced mechanical seal

Material design: Casing seal: The casing is sealed by a flat type seal of special paper. Code of this construction: 2 Drive / Speed: By commercial electric motors, type IM B 5 resp. IM V 1. The max. admissible speed n = 3600 rpm, out of pump size 100-160 (max. speed n = 3000 rpm). Mounting position: ZTI pumps can be mounted either horizontally or vertically into pipe systems with sufficient carrying capacity, with this the drive power has to be taken into consideration: Horizontal installation up to 7,5 kW Vertical installation up to 7,5 kW possible, from 11 kW necessary. For this...

Sectional drawing and Nomenclature Shaft sealing Volute casing casing cover bearing bracket radial shaft seal ring mechanical seal casing shaft seal Heat blocking / shaft sealing / bearings Heat transfer plants have reached a high state of technical development. Therefore pumps handling heat carriers are facing, with regard to safety of operation, environmental neutrality, maintenance facility, and operating costs, much severer requirements now than in former times. The type ZTI based on many years of experience and on the most up-to-date know-how, fully complies with these requirements. By...
