APPLICATION
When developing the unit construction type volute pumps of series
ZTKD, the main objective has been to turn out a number of floor
space saving, easy-installation types especially adapted to the
circulation of mineral and synthetic heat carriers in
primary
secondary and
tertiary
circuits.
Besides these units can advantageously be used as main
circulating pumps in heat exchangers of
compact design
where they, owing to their constructional features, offer brand-new
possibilities to the plant manufacturer for the layout of a system.
DESIGN
Single-stage pumping units of compact design. Nominal
performances and flange connection sizes according to DIN 24255
/ EN 733.
There is no common shaft for motor and pump, the motors used
are of the standard type listed.
Owing to the process design, it is possible to withdraw the whole
insert assembly without removing the casing of the pump from the
piping system.
The individual shafts of the unit connected by a plug-in coupling
facilitate the dismantling or replacement of the motor without
affecting the pump.
The DIN 4754 specifications are complied with.
At present, the programme comprises 9 pump sizes.
CONSTRUCTION
Casing pressure:
Max. 16 bar from 0 °C to 120 °C
Max. 13 bar from 120 °C to 300 °C
Max. 10 bar from 300 °C to 350 °C
Intermediate values can be interpolated
Please note:
Technical rules and safety regulations.
Casing pressure = inlet pressure + zero delivery head
Permissible inlet pressure (system pressure) 5 bar
Permissible inlet pressure = permissible casing pressure at
shaft sealing GBC
