APPLICATION
Series CBT• volute-casing pumps can be used where the
requirement is for pumping of clear or slightly dirty or even
corrosive liquids.
Series CBT• pumps are therefore suitable for use in the:
chemical and petrochemical industries
pharmaceutical industries
plastic and rubber industries
ferrous and non-ferrous metal industries
paper and cellulose industries
textile industries
food and drink industries
thermal power stations
municipal water supply and irrigation
particularly in applications in:
all processing plants,
pumping of acids, brine and alkalis and all types of
hydrocarbons,
surface treatment and surfacing hardening of metal, e.
g. galvanizing, anodizing, phosphatizing,
desalination and extractions plants,
in heating engineering for circulation of water and
other heat transfer fluids,
water treatment and supply,
treatment of industrial effluents.
DESIGN
Process type, single-stage, volute casing pumps with design
features and nominal rating to ISO2858/EN22858. For pumping
of liquids with high temperatures (200ºC) special executions with
centre line feet are available (RBT•) upon request.
The process design permits dismantling of the complete bearing
unit towards the drive end, without the pump casing having to be
disconnected from the piping. If a spacer coupling is used it is
also unnecessary to disconnect the motor.
The list comprises 20 pump sizes, with maximum
interchangeability, these are covered with four bearing housing
sizes.

DIN 2543 PN 16 for stainless steel.
Flanges can be supplied drilled to ANSI
Bearings:
One oil lubricated deep grove ball bearing to DIN 625 on the
pump end, two single-row angular contact ball bearings in an
O arrangement on the drive end.
• Oil level control by constant level oiler as standard.
• Bearing brackets are optional equipped with tapped holes
for installation of temperature/vibration sensors.
• Oil bath cooling can be provided.
