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.
