Volute pumps for heat carrier oils up to 350 C SIHI SuperNova ZTND 032-125... -500 TECHNICAL DATA Output: max. 0 m³/h Delivery head: max. 95 m Speed: max. 3600 rpm Temperature: max. 350 C Casing pressure: PN 16 Shaft sealing: radial seal rings or mechanical seal Flange connection: DIN EN 1092-2 PN 16 / 25 1) Direction of rotation: clockwise, when looking at the pump from the drive end APPLICATION Volute pumps of the series ZTN have been specially developed for handling of mineral and synthetic heat transfer oils. The pumps may be used in installations with positive or negative suction pressure. Especially to be emphasised is the application in plants of: The chemical industry: heating of agitators, reactors, drying plants, polymerisation plants, plants for conveying high-viscous products and producing plastic materials and synthetic fibres. The rubber and plastic industry: heating of calendars, melting pots, power presses for plastics, automatic injection moulding machines, production of PVC adhesive tape. The food industry: heating of baking and fish-frying ovens, distillation of fatty acids and glycerine, fat softening plants, production of potato chips and milk powder. The paper industry and laundries: calendar rolls, production of corrugated cardboard, heating of washing machines, mangles and dryers. DESIGN Horizontal, single-stage volute pumps with the dimensions and nominal ratings to 24255/EN 733 in back pull out design* which permits the removal of the complete bearing unit toward 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 programme comprises 38 pump sizes, but only three shaft assemblies are required owing to the unit construction system. Within each shaft assembly, shafts, shaft sealing, impeller fastenings, bearing bracket and bearing covers are interchangeable. The DIN 4754 regulations are complied with. Should heat carrier seepage occur from the shaft seal, it is ensured that the leakage will be drained off and collected completely. 1) from size 150315 to 500 * due to additional sizes the performance range is increased to higher output rates. CONSTRUCTION Casing pressure: Maximal 16 bar from 0 C to 120 C Maximal 13 bar from 120 C to 300 C Maximal 10 bar from 300 C to 350 C Intermediate values can be obtained by interpolation. Please note: Technical rules and safety regulations. Max. Casing pressure = inlet pressure + zero head Admissible inlet pressure (system pressure) = 5 bar when using shaft sealing 002. Admissible inlet pressure = admissible casing pressure when using shaft sealing GBC. Flanges location: Axial suction flange, discharge flange radially upwards. Flanges: The flanges comply with DIN EN1092-2/PN 16, resp. PN 25. Flanges drilled to according to ANSI (previous ASA) 150 can be supplied. Hydraulic: Designation of this construction type: A, B, D Bearing: One grease-lubricated grooved ball bearing resp. 2 inclined ball bearings (the first grease filling is made in the factory) and one internal liquid flushed sleeve bearing. Designation of this construction type:. A Direction of rotation: Clockwise, when looking at the pump from the drive end. Shaft sealing: Code 002: Code GBC: several radial shaft seal rings arranged in in series; uncooled unbalanced bellows mechanical seal seal face materials cast chromium steel/carbon elastomer FPM (Viton) Tech_cat_e_ZTND.doc 18/9/09 Designs are subject to amendment without prior notice.

Consequently the requirements on pumps handling heat transfer oils have increased regarding operating safety, environmental protection, maintenance and operating costs. The Sterling SIHI ZTN pump, based on many years of experience and on the latest technical know-how, fully complies with these requirements. By the heat barrier with integrated throttle gab, located behind the cover, a favourable drop in temperature toward the drive side is achieved (see opposite drawing). Heat losses at the product side are effectively prevented (saving of energy). The reduced temperature allows the use of simple, uncooled type of shaft sealing. As the lubricating properties of heat transfer oils for antifriction bearings are not specially good, a liquid flushed sleeve bearing has been fitted at the impeller side and an antrifriction bearing, not in contact with the heat carrier, has been fitted behind the shaft sealing. By this arrangement noiseless operation and long working life have been achieved. Designs are subject to amendment without prior notice. (Sterling Fluid Systems BV) 1
