Technical data

• Permissible temperature range up to
+350 °C, dependent on max. operating
pressure:
0 °C … 120 °C (16 bar)
120 °C … 300 °C (13 bar)
300 °C … 350 °C (16 bar)
• Nominal diameter on pressure side
DN 32 to DN 125
• Max. operating pressure PN 16

Equipment/function

• Single-stage, horizontal centrifugal
pump with axial suction connection and
radial pressure upwards-facing pressure
connection
• Dimensions and hydraulic output as
per EN 733
• Self-cooling design with double
temperature barrier allows the use of an
uncooled shaft seal, reducing heat loss.
• Standard mechanical seal corresponding
to heat carrier medium
• Version with or without spacer coupling
• 2 or 4-pole IEC standard motor 50 Hz
• Delivered as complete unit (pump,
coupling, coupling protection, motor
and baseplate) or without motor or only
pump with free shaft end

Special features

Impeller diameter is adjusted to the
dutypoint as appropriate
• 60 Hz or ATEX version on request
