APPLICATION

nnnn

Volute pumps of the series ZTN have been specially developed for

nnnn

handling of mineral and synthetic heat transfer oils. The pumps

nnnn

may be used in installations with positive or negative suction

nnnn

pressure.

nnnn

Especially to be emphasised is the application in plants of:

nnnn

The chemical Industry:

nnnn

heating of agitators, reactors, drying plants, polymerisation

nnnn

plants, plants for conveying high-viscous products and

nnnn

producing plastic materials and synthetic fibres.

nnnn

The rubber and plastic Industry:

nnnn

heating of calendars, melting pots, power presses for

nnnn

plastics, automatic injection moulding machines, production

nnnn

of PVC adhesive tape.

nnnn

The food Industry:

nnnn

heating of baking and fish-frying ovens, distillation of fatty

nnnn

acids and glycerine, fat softening plants, production of potato

nnnn

chips and milk powder.

nnnn

The paper Industry and laundries:

nnnn

calendar rolls, production of corrugated cardboard, heating

nnnn

of washing machines, mangles and dryers.

nnnn

DESIGN

nnnn

Horizontal, single-stage volute pumps with the dimensions and

nnnn

nominal ratings to 24255/EN 733 in back pull out design* which

nnnn

permits the removal of the complete bearing unit toward the drive

nnnn

end without removing the pump casing from the pipe work. If a

nnnn

spacer coupling is installed it is also unnecessary to disconnect the

nnnn

motor.

nnnn

The programme comprises 38 pump sizes, but only three shaft

nnnn

assemblies are required owing to the unit construction system.

nnnn

Within each shaft assembly, shafts, shaft sealing, impeller

nnnn

fastenings, bearing bracket and bearing covers are inter-

nnnn

changeable.

nnnn

The DIN 4754 regulations are complied with.

nnnn

Should heat carrier seepage occur from the shaft seal, it is

nnnn

ensured that the leakage will be drained off and collected

nnnn

completely.

nnnn

1 ) from size 150315 to 200500

nnnn

* due to additional sizes the performance range is increased to

nnnn

higher output rates.

CONSTRUCTION

nnnn

Casing pressure:

nnnn

Maximal 16 bar from 0°Cto120°C

nnnn

Maximal 13 bar from 120 °C to 300 °C

nnnn

Maximal 10 bar from 300 °C to 350 °C

nnnn

Intermediate values can be obtained by interpolation.

nnnn

Please note:

nnnn

Technical rules and safety regulations.

nnnn

Max. Casing pressure = inlet pressure + zero head

nnnn

Admissible inlet pressure (system pressure) = 5 bar when

nnnn

using shaft sealing 002.

nnnn

Admissible inlet pressure = admissible casing pressure when

nnnn

using shaft sealing GBC.

nnnn

Flanges location:

nnnn

Axial suction flange, discharge flange radially upwards.

nnnn

Flanges:

nnnn

The flanges comply with DIN EN1092-2/PN 16, resp. PN 25.

nnnn

Flanges drilled to according to ANSI (previous ASA) 150 can

nnnn

be supplied.

nnnn

Hydraulic:

nnnn

Designation of this construction type: A, B, D

nnnn

Bearing:

nnnn

One grease-lubricated grooved ball bearing resp. 2 inclined

nnnn

ball bearings (the first grease filling is made in the factory) and

nnnn

one internal liquid flushed sleeve bearing.

nnnn

Designation of this construction type: A

nnnn

Direction of rotation:

nnnn

Clockwise, when looking at the pump from the drive end.

nnnn

Shaft sealing:

nnnn

Code 002: several radial shaft seal rings arranged in

nnnn

in series; uncooled

nnnn

Code GBC: unbalanced bellows mechanical seal

nnnn

seal face materials cast chromium steel/carbon

nnnn
