nnnnAPPLICATION
nnnnSeries CBT» volute-casing pumps can be used where the
nnnnrequirement is for pumping of clear or slightly dirty or even
nnnncorrosive liquids.
nnnnSeries CBT» pumps are therefore suitable for use in the:
nnnnchemical and petrochemical industries
nnnnpharmaceutical industries
nnnnplastic and rubber industries
nnnnferrous and non-ferrous metal industries
nnnnpaper and cellulose industries
nnnntextile industries
nnnnfood and drink industries
nnnnthermal power stations
nnnnmunicipal water supply and irrigation
nnnnparticularly in applications in:
nnnnall processing plants,
nnnnpumping of acids, brine and alkalis and all types of
nnnnhydrocarbons,
nnnnsurface treatment and surfacing hardening of metal, e.
nnnng. galvanizing, anodizing, phosphatizing,
nnnndesalination and extractions plants,
nnnnin heating engineering for circulation of water and
nnnnother heat transfer fluids,
nnnnwater treatment and supply,
nnnntreatment of industrial effluents.
nnnnDESIGN
nnnnProcess type, single-stage, volute casing pumps with design
nnnnfeatures and nominal rating to IS02858/EN22858. For pumping
nnnnof liquids with high temperatures (>200°C) special executions with
nnnncentre line feet are available (RBT») upon reguest.
nnnnThe process design permits dismantling of the complete bearing
nnnnunit towards the drive end, without the pump casing having to be
nnnndisconnected from the piping. If a spacer coupling is used it is
nnnnalso unnecessary to disconnect the motor.
nnnnThe list comprises 20 pump sizes, with maximum
nnnninterchangeability, these are covered with four bearing housing
nnnnsizes.
nnnnCONSTRUCTION
nnnnSizes with single volute casing:
nnnn100160, 125200, 150200, 150315, 150400, 150500
nnnn200250, 200315, 250300, 250315
nnnnSizes with single volute casing with diffuser:
nnnn150630, 200630
nnnnSizes with double volute casing:
nnnnRemaining sizes.
nnnnCasing pressure:
nnnnMaterial execution: | GG | GGG | Stainless steel |
Temperature: -10 to 120 °C Temperature: -20 to 120 °C Temperature: 120 to 200 °C | 16 | 25 25 16 | 16 16 10 |
Please note:
nnnnCasing pressure = Inlet pressure + shut off head.
nnnnmax test pressure = GGG 33 bar; GG and SS 21 bar
nnnnBranch positions:
nnnnSuction branch axial, discharge branch radially upwards.
nnnnFlanges:
nnnnDIN 2533 PN 16 for GG25.
nnnnDIN 2534 PN 25 for GGG-40.3.
nnnnDIN 2543 PN 16 for stainless steel.
nnnnFlanges can be supplied drilled to ANSI
nnnnBearings:
nnnnOne oil lubricated deep grove ball bearing to DIN 625 on the
nnnnpump end, two single-row angular contact ball bearings in an
nnnnO arrangement on the drive end.
nnnn• Oil level control by constant level oiler as standard.
nnnn• Bearing brackets are optional equipped with tapped holes
nnnnfor installation of temperature/vibration sensors.
nnnn• Oil bath cooling can be provided.
