200MS Series High-PressureMultistage Centrifugal Pumps:The introduction of the WaukeshaCherry-Burrell 200 Series, Heavy-Duty Centrifugals set a newstandard for higher efficiency,minimal vibration and longer life.Many of the same features ofthe 200 Series pumps, includingstrong investment cast impellers,low NPSH requirements andtighter running clearances, havebeen included in the 200MS highpressuremultistage.Especially designed forrecirculating service in reverseosmosis and other membranesystems, the 200MS Seriespumps offer lower start-up andrun costs due to the highefficiency two impeller design.Moreover, they produce a smooth,constant flow rate that reducesRO membrane fouling.The 200MS Series pumps areequipped with a balanced,double-shaft seal with buffer fluidports on top and bottom forcomplete removal of air/vaporfrom the seal chamber.The smoother flowing, highefficiency,cost saving alternativefor high-pressure applicationsOperating Features• Cost competitive two stage design.• High efficiency and low noise; precision,heavy-duty, machined cover and diffusermanufactured to tight tolerances.• Easier on RO membranes than piston pumpswith a smooth, constant, flow rate and lessmembrane fouling.• Up to 235 psi pump differential pressure.• Up to 1250 psi maximum casing pressure whenpumps are placed in series.• Sanitary 3A construction for dairy and foodprocessing; wet end parts 316L stainless steel.• CIPable.• Save on maintenance costs; uses many commoncomponents with 200 Series pumps; easy takedown andassembly shortens downtimes.• Flush type seal, standard.Long-life features• Negligible shaft deflection due to rigid shaft.• Large, long-life bearings with non-wearing, labyrinth seals.• Coupling wear reduced by motor flange adapter design.2 Waukesha Cherry-Burrell
