Dean Pump Series pHCentrifugal Process Pumps Capacities to 3200 GPM (726 m3/hr) Heads to 800 feet (245 m) Pumping temperatures to 500 F (260 C) Working presures to 375 PSIG (2585 kPa)ExperienceDean Pump is recognized as an industry leader in the design and manufactureof horizontal centrifugal process pumps used extensively in the chemical andpetrochemical industries, power plants, pulp and paper, mining, pharmaceutical andfood processing industries.When Dean Pump introduced the pH centrifugal process pump in 1958, the chemicalprocessing industry recognized it as the model for the proposed ASA StandardChemical Pump. Shortly thereafter, the Manufacturing Chemist Association (MCA)adopted, with minor changes, the service proven Dean pH pump as the AmericanVoluntary Standard (AVS). Subsequently, the American National Standards Instituteapproved the AVS Specifications as national standard B123.1-1971. This standardwas later revised and approved as ANSI/ASME B73.1M-1984. Dean Series pHpumps continue to meet or exceed the latest revised B73.1 standard.Dean Series pH 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 pH pump is an end-suction back pull out design regularly availablein 22 sizes and divided into four size classifications: the pH2110 Series in 5 sizes the pH2140 Series in 11 sizes the pH2170/pH3170 Series in 4 sizes the pH2180 Series in 2 sizesMaterialsStandard materials of construction include ductile iron, 316SS, CD4MCu, and Alloy20. Additional higher metal alloys (Hastelloy B and C, Titanium, etc.) are availableupon request. (Standard Materials of Construction chart is available on Page 3).Parts InterchangeabilityThe Series pH provides the ultimate in standardization of process pumps. With wideparts interchangeability among pump sizes, fewer parts are required for inventory. Acomplete stock of spare parts is readily available from Dean Pump or its network ofstocking distributors, thereby reducing shipping time to a minimum.All Series pH parts, with the exception of the casing (and in some sizes, the impeller),are interchangeable with the Series pHP Self-Priming Pump.Shaft SealingDean Pump offers a broad line of mechanical seals and standard packing sets to solvethe most difficult sealing problems. This feature gives Series pH pumps the versatility tohandle a wide range of chemical services. A variety of seal chambers such as standardbore, jacketed, large taper bore, and large cylindrical bore are available for specificapplications.2

1. CASING COVERStandard bore, jacketed, large taper bore, largecylindrical bore. Designed to provide the bestenvironment for the specific application andservice conditions.12. INTEGRAL ONE-PIECE CASING FLANGESFlanges dimensioned according to ANSI/ASMEB16.5 Class 150 for the pH2110/pH2140/pH2170and Class 300 for the pH3170/pH2180. Flat faceflanges are standard with raised face flanges available as an option.33. SEALING FLEXIBILITYChoice of packed box or mechanical seal. Widerange of sealing arrangements (inside/outside,single/double, balanced/unbalanced, etc.)available to meet specific application and serviceconditions.24. FULLY OPEN IMPELLERThe fully open design provides smooth inlet passagesfor solids handling and stringy material, low NPSH,and minimum stuffing box pressure. The impellerdesign transmits low axial loads on the bearings.5. SHAFT SLEEVE“Hook” type shaft sleeves are standard. Alloy,hard-facing, hardened chrome 11/13, or ceramiccoatings are available as options. Solid shafts arealso available.6. ANSI/ASME B73.1 DIMENSIONAL CASINGPermits maximum interchangeability of pumps withexisting ANSI pumps eliminating any need forpiping or foundation changes. Back pull-out designfor ease of maintenance. Top centerline discharge forself-venting of casing. Casing drain/plug is astandard feature on Ductile Iron construction only.457. HEAVY DUTY SHAFT AND BEARINGSCarbon steel shaft (316SS optional) designed forminimum deflection of less than 0.002” (0.05 mm) atthe seal faces. Double row thrust bearings and singlerow radial bearings are sized for a 2 year minimumlife and a 10 year average life. With minimizedbearing spans and overhung lengths, Dean’s L3/D41346

ratio is one of the best in the business.8. STANDARD LABYRINTH SEALSRugged bronze construction with Viton O-rings.These seals will ensure that the bearings are keptproperly lubricated and uncontaminated throughouttheir project design life.89. EXTERNAL IMPELLER ADJUSTMENTNo shimming required. Allows field setting ofimpeller-to-casing clearance. Impeller adjustment isaccomplished by adjusting screws in the bearing endcover.910. LUBRICATION OPTIONSOil bath lubrication is standard. Extra large oilreservoir designed for cooler bearing operation.Oil mist lubrication and grease lubrication areoptional features. A finned tube oil cooler is alsoavailable (as an option) to directly cool oil forlower bearing temperature.11. FILL PLUGEasy access to fill plugs supplied on both sides ofthe bearing housing. Designed to minimize thepossibility of overfilling.12. ONE INCH OIL SIGHT GLASSAllows for simple and easy monitoring of oil leveland condition. Oil sight glass can be installed oneither side of the bearing housing, in the field, forbest location and ease of viewing. Combinationautomatic (bottle) oiler/sight glass also available.1013. RIGID BEARING HOUSING AND CASING FEETDesigned to reduce the effect of pipe loads on pumpand shaft alignment.11712135
