Pump modulesAll the made-to-stock CR pump modules canhandle the most demanding of liquids andpressures – and be adjustable to virtuallyany requirement. Of course, the modulescan be combined in multiple ways making itpossible for us to provide you with a pumpsolution that matches your specific needs.CR pumps come in many flow sizes and variousgrades of corrosion-resistant stainlesssteel – and an all-titanium variant.What follows is an overview of some of themost common CR pump variants offeredby Grundfos. However, the overview coversonly a fragment of the total pump range.Please do not hesitate to contact Grundfosif your requirements are not covered by theoverview.• High inlet pressure• High-pressure pump systems required (up• to 50 bar)• Pumping of gas or particle-entrained liquids• Pumping of high-viscosity or sticky liquids• Low NPSH level• Horizontal pump mounting• No carbon or silicone allowedSolution Description PhotoLow NPSHpumpDeep-wellAll stainlesssteelFor applications involving poor inlet conditions,e.g. boiler feed, special low NPSH versions areavailable to reduce NPSH and eliminatecavitation.For applications involving pumping fromdeep boreholes (down to 90 metres, a specialdeep-well CR pump with an ejector for abovegroundinstallation is available.For applications exposed to corrosiveatmosphere, e.g. maritime applications orwhere frequent wash-down occurs, a stainlesssteel base plate and motor stool are available.All parts exposed to the corrosive installationenvironment is thus made of stainless steel.Solution Description PhotoSilicon-freesolutionRubbermaterialsPump bearingsFor processes that require no silicon,e.g. paint industry, 100% silicon-free solutionsare available.Pumps fitted with chemical resistantFXM (Fluoraz ® ) or FFKM (Kalrez ® ) rubberO-rings are available for applications,where the liquid may damage standardO-ring materials such as EPDM, FKM andViton ® .A wide variety of bearing materials areavailable to suit any application, e.g.silicium carbide, bronze, tungsten carbide,and carbon-filled PTFE.CR/CRI/CRN/CRT – MULTISTAGE CENTRIFUGAL PUMP• Special materials requiredHorizontalmountingCertain situations require the pumps to bemounted horizontally.The CR pumps can be designed to fitinstallations with limited height, vehicles,ships or earthquake prone areas.Bearing flangeFor applications with extremely high inletpressures, a special flange is necessary tocounterhold the shaft. It also allowsmounting of standard IEC34 or NEMA motors.End-suction base can be supplied as option.RefrigerantpumpFor applications handling temperatures downto -40°C, special coolant pumps are available.Because of different thermal coefficient ofexpansion, special design is required.High pressurepumpsFor high pressure applications, special single ordouble pump solutions are available. Thesepumps are capable of generating up to nearly 50bar pressure.To avoid high pressure near the vulnerable shaftseal, the hydraulic design of high pressure pumpsensures that the highest pressure is generatedat the base of the pump, farthest away from theshaft seal.Carbon-freesolutionFor processes that require carbon-freeinstallations, e.g. electronics industry.Belt-driveFor applications in remote areas or mobileapplications, where electric power is notavailable, belt-driven pumps powered bye.g. a diesel engine or a steam turbine,can be supplied.16 17
