APPLICATION

nnnn

Series CBT» volute-casing pumps can be used where the

nnnn

requirement is for pumping of clear or slightly dirty or even

nnnn

corrosive liquids.

nnnn

Series CBT» pumps are therefore suitable for use in the:

nnnn

chemical and petrochemical industries

nnnn

pharmaceutical industries

nnnn

plastic and rubber industries

nnnn

ferrous and non-ferrous metal industries

nnnn

paper and cellulose industries

nnnn

textile industries

nnnn

food and drink industries

nnnn

thermal power stations

nnnn

municipal water supply and irrigation

nnnn

particularly in applications in:

nnnn

all processing plants,

nnnn

pumping of acids, brine and alkalis and all types of

nnnn

hydrocarbons,

nnnn

surface treatment and surfacing hardening of metal, e.

nnnn

g. galvanizing, anodizing, phosphatizing,

nnnn

desalination and extractions plants,

nnnn

in heating engineering for circulation of water and

nnnn

other heat transfer fluids,

nnnn

water treatment and supply,

nnnn

treatment of industrial effluents.

nnnn

DESIGN

nnnn

Process type, single-stage, volute casing pumps with design

nnnn

features and nominal rating to IS02858/EN22858. For pumping

nnnn

of liquids with high temperatures (>200°C) special executions with

nnnn

centre line feet are available (RBT») upon reguest.

nnnn

The process design permits dismantling of the complete bearing

nnnn

unit towards the drive end, without the pump casing having to be

nnnn

disconnected from the piping. If a spacer coupling is used it is

nnnn

also unnecessary to disconnect the motor.

nnnn

The list comprises 20 pump sizes, with maximum

nnnn

interchangeability, these are covered with four bearing housing

nnnn

sizes.

nnnn

Please note:

nnnn

Casing pressure = Inlet pressure + shut off head.

nnnn

max test pressure = GGG 33 bar; GG and SS 21 bar

nnnn

Branch positions:

nnnn

Suction branch axial, discharge branch radially upwards.

nnnn

Flanges:

nnnn

DIN 2533 PN 16 for GG25.

nnnn

DIN 2534 PN 25 for GGG-40.3.

nnnn

DIN 2543 PN 16 for stainless steel.

nnnn

Flanges can be supplied drilled to ANSI

nnnn

Bearings:

nnnn

One oil lubricated deep grove ball bearing to DIN 625 on the

nnnn

pump end, two single-row angular contact ball bearings in an

nnnn

O arrangement on the drive end.

nnnn

• Oil level control by constant level oiler as standard.

nnnn

• Bearing brackets are optional equipped with tapped holes

nnnn

for installation of temperature/vibration sensors.

nnnn

• Oil bath cooling can be provided.
