APPLICATION

nnnn

When developing the unit construction type volute pumps of series

nnnn

ZTKD, the main objective has been to turn out a number of floor

nnnn

space saving, easy-installation types especially adapted to the

nnnn

circulation of mineral and synthetic heat carriers in

nnnn

primary

nnnn

secondary and

nnnn

tertiary

nnnn

circuits.

nnnn

Besides these units can advantageously be used as main

nnnn

circulating pumps in heat exchangers of

nnnn

compact design

nnnn

where they, owing to their constructional features, offer brand-new

nnnn

possibilities to the plant manufacturer for the layout of a system.

nnnn

DESIGN

nnnn

Single-stage pumping units of compact design. Nominal

nnnn

performances and flange connection sizes according to DIN 24255

nnnn

/ EN 733.

nnnn

There is no common shaft for motor and pump, the motors used

nnnn

are of the standard type listed.

nnnn

Owing to the process design, it is possible to withdraw the whole

nnnn

insert assembly without removing the casing of the pump from the

nnnn

piping system.

nnnn

The individual shafts of the unit connected by a plug-in coupling

nnnn

facilitate the dismantling or replacement of the motor without

nnnn

affecting the pump.

nnnn

The DIN 4754 specifications are complied with.

nnnn

At present, the programme comprises 9 pump sizes.

nnnn

CONSTRUCTION

nnnn

Casing pressure:

nnnn

Max. 16 bar from 0°Cto120°C

nnnn

Max. 13 bar from 120 °C to 300 °C

nnnn

Max. 10 bar from 300 °C to 350 °C

nnnn

Intermediate values can be interpolated

nnnn

Please note:

nnnn

Technical rules and safety regulations.

nnnn

Casing pressure = inlet pressure + zero delivery head

nnnn

Permissible inlet pressure (system pressure) 5 bar

nnnn

Permissible inlet pressure = permissible casing pressure at

nnnn

shaft sealing GBC

nnnn

Position of branches:

nnnn

Axial suction flange; discharge flange radially upwards.

nnnn

Flanges:

nnnn

The flanges correspond to DIN EN 1092-2 / PN 16.

nnnn

Flange design drilled as per ANSI 150 is possible.

nnnn

Hydraulic:

nnnn

First Hydraulic: Design code A

nnnn

Second Hydraulic: Design code B

nnnn

Bearing:

nnnn

A groove ball bearing acc. to DIN 625 grease lubricated for

nnnn

service life. A liquid surrounded step bearing in the pump.

nnnn

Code of this construction: A

nnnn

Sense of rotation:

nnnn

Clockwise when seen from drive on the pump.

nnnn
