CHTR – Centrifugal, High[pressure, Multistage Barrel Pump to ... - KSB

Oil & GasCHTR – Centrifugal, High-pressure,Multistage Barrel Pump to API 610, 10 th Edition.

2IntroductionCHTR – Reliable deliveryat high pressure.Day in and day out, KSB pumps prove their worth again and again,delivering a consistently high level of quality and reliability.Are your pumps exposed to extreme temperatures and need to copewith gaseous fluids? Are your system components and pumpssubject to on-going tough conditions? KSB can handle the pressure.Our team works hand in hand with engineers from the oil and gasindustries to provide the most appropriate and efficient solutionfor your processes.Single and double-entry CHTR multistage barrel pumps areavailable in 5 sizes – with up to 16 stages for over 30 hydraulicconfigurations. This modular design combined with the standardoption of turning down impellers guarantees the optimum andmost efficient solution at all times. CHTR pumps can thereforebe matched to the specific needs and requirements of a wide rangeof processes:Small capacities at high pressureLarge capacities at medium pressureOperation around the clockPeriodic operation at short intervals

3CHTR – Smooth operator in extreme situations.Reliable KSB quality guarantees that processes in the oil and gasindustries keep working at their best. The all-rounder CHTR offersseveral features to ensure everything runs smoothly – even underthe most severe conditions. For example:KSB Total Pump Management.In order to offer our customers the best possible system optimisation,KSB subscribes to the philosophy of Total Pump Management:Ongoing support from pre-sales to after-salesExtremely durable rigid pump shaftsLong interstage bushes and wear ringsKSB expertise in selecting robust materialsConfiguration of processes for maximum efficiencyand minimum maintenanceReduction of stages to keep investment costs lowMinimisation of NPSH values through choice of singleor double-entry suction stage impellers
