Dean Pump Series R4000Centrifugal Process Pumps Capacities to 5000 GPM (1135 m3/hr) Heads to 800 feet (245 m) Pumping temperatures to 850 F (454 C) Working pressures to 500 PSIG (3445 kPa)ExperienceDean Pump is recognized as the industry leader in the design and manufactureof horizontal hot oil/hot water centrifugal process pumps used extensively in thefollowing industries: chemical and petrochemical plants, power plants, plastics, heattransfer OEMs, commercial (hospitals, universities, laboratories), government facilities,pharmaceutical, and food processing.Dean Series R centrifugal process pumps are designed to insure long, continuousservice life at low cost. Each phase in the production of these pumps is meticulouslymonitored by an independent quality control department.Pump SizesThe Dean Series R pump is an end-suction, center line supported, back pull out designregularly available in 27 sizes and divided into four size classifications: the R4140 Series in 17 sizes the R4170 Series in 3 sizes the R4180 Series in 5 sizes the R4240 Series in 2 sizesMaterialsStandard materials of construction include carbon steel and 316SS. (StandardMaterials of Construction chart is available on Page 3).Parts InterchangeabilityThe Series R provides the ultimate in standardization. With wide parts interchangeability among pump sizes, fewer parts are required for inventory. A complete stock ofspare parts is readily available from Dean Pump or its network of stocking distributors,thereby reducing shipping time to a minimum.Shaft SealingDean Pump offers a broad line of mechanical seals and standard packing sets to solvethe most difficult sealing problems. Jacketed standard bore (stuffing box), and largetaper bore, seal chambers are available for specific applications.2

1. CASING COVERJacketed standard bore or large taper bore. Designedto provide the best environment for the specificapplication and service conditions.2. INTEGRAL ONE-PIECE CASING FLANGESFlanges dimensioned according to ASME/ANSI B16.5Class 300. Raised face flanges are standard. Ring typejoint flanges (Class 300) are available as an option.3. SEALING FLEXIBILITYChoice of packed box or mechanical seal. Wide rangeof sealing arrangements (inside/outside, single/double,balanced/unbalanced, etc.) available to meet specificapplication and service conditions.244. CLOSED IMPELLERAllows thermal expansion of the pump shaft at highpumping temperatures without interference of the impellerwith the casing or the casing cover. Keyed to shaft withpositive locking device. Replaceable wear rings optional.5. SHAFT SLEEVEReplaceable “hook type” shaft sleeves provided asstandard. Allows replacement of the wearing surfacewithout having to replace the pump shaft or the bearings.The design allows the shaft sleeve to expand thermally,independent of the pump shaft. The standard sleevematerial is 316SS. Sleeves of alloy construction,hard-facing, hardened chrome 11-13%, or ceramiccoatings are available as options. Solid sleeveless shaftsare also available.6. CENTERLINE CASING SUPPORTThe pump is supported at the horizontal centerline of thecasing so that the thermal expansion of the casing will notaffect the shaft alignment.7. CASING FEETThree different foot designs are available. The standard isa “yoke” design, available on R4140/4170 only, whichallows the pump to fit on an ASME/ANSI B73.1baseplate (as well as Dean’s “Economy” baseplates).6The second “pedestal” design allows for mounting onAPI-type baseplates.The last design is a “water-cooled” pedestal design(as shown) used specifically for severe service conditionsand applications.88. COOLING PIPINGOptional tubing (as shown) connects the “watercooled” pedestal design with the casing cover jacket.Also available is optional tubing that connects thecasing cover jacket with the finned tube oil cooler,and/or tubing that connects the cooled pedestal feetwith the casing cover jacket.4

9. HEAVY DUTY SHAFT AND BEARINGSCarbon steel pump shaft (316SS optional) isdesigned for a maximum deflection of less than0.002” (0.05mm) at the mechanical seal faces. Theduplex mounted angular contact thrust bearings andthe single row, deep groove, radial bearing are sizedfor a 2 year minimum life and a 10 year averagelife.1013810. STANDARD LABYRINTH SEALSRugged bronze construction with Viton O-rings.Magnetic face seals are also an option for all pumps.11. LUBRICATION OPTIONSOil bath lubrication is standard. The extra large oilreservoir is designed for cooler bearing operation.The bearing housing is set up to accommodate oilmist lubrication and grease lubrication as available options. The finned tube oil cooler is providedas standard, to directly cool the oil for lowerbearing temperature.91412. FILL PLUGEasy access to fill plugs supplied on both sides ofthe bearing housing. Designed to minimize thepossibility of overfilling.13. ONE INCH OIL SIGHT GLASSAllows for simple and easy monitoring of oil leveland condition. The sight glass can be installed oneither side of the bearing housing, in the field, forbest location and ease of viewing. A combinationautomatic (bottle) oiler/sight glass is an availableoption.1514. BREATHER VENTA filtered bearing housing breather is standard. Anoptional expansion chamber is available that is usedwith the optional magnetic oil seals when a sealedbearing housing is desired.12131115. PILOT AND BOLT HOLESThe bearing housing of the R4140 is supplied with apilot fit and four bolt holes at the motor end. Theholes allow for mounting of the telescoping couplingguard. The pilot fit also allows for use of an optional“C-Face” motor support. The support permits selfaligning of the motor shaft to the pump shaft.575
