SIHI SuperNova Pump ZTN – Hot Oil

SIHI SuperNova Pump ZTN is a Heat Transfer Pump for circulating thermal oil.

It is a horizontal, single-stage volute casing pump with the dimensions and nominal ratings to 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. A spacer type coupling is standard making re-alignment unnecessary.

SIHI SuperNova Pump ZTN pumps have been specially developed for handling of mineral and synthetic heat transfer oils. There are also ZTK and ZTI close coupled pumps. The pumps may be used in installations with positive or negative suction pressure. They are especially suited to the listed applications in the following industries:

  • Chemical industry (heating of agitators, reactors, drying plants, polymerisation plants, plants for conveying high-viscous products and producing plastic materials and synthetic fibres)
  • Rubber and Plastic industry (heating of calendars, melting pots, power presses for plastics, automatic injection moulding machines, production of PVC adhesive tape)
  • 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)
  • Paper industry and Laundries (calendar rolls, production of corrugated cardboard, heating of washing machines, mangles and dryers).

Technical Data:

  • Flow rate: up to 1,000 m³/h
  • Head: up to 95 m
  • Speed: max. 3,600 rpm
  • Temperature: Max. 350 °C – without the need for any cooling
  • Casing pressure: up to 16 bar
  • Shaft seal: mechanical seal, radial lip seals
  • Material: nodular iron, cast steel
  • Flange connection: DIN EN 1092-2 PN 16 / 25 1)
  • Direction of rotation: clockwise, when looking at the pump from the drive end

The series 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.
