CECO Dean PumpsANSI/ASME B73.1 Horizontal Process PumpsCECO Dean pH Series Centrifugal Process Pumps Capacities to 3200 GPM (726 m3/hr) Heads to 800 feet (245 m) Pumping temperatures to 500 F (260 C) Working pressures to 375 PSIG (2585 kPa)ExperienceDean Pump is recognized as an industry leader in the design and manufacture of horizontal centrifugalprocess pumps used extensively in the chemical and petrochemical industries, power plants, pulp andpaper, mining, pharmaceutical and food processing industries.When Dean Pump introduced the pH centrifugal process pump in 1958, the chemical processing industryrecognized it as the model for the proposed ASA Standard Chemical Pump. Shortly thereafter, theManufacturing Chemist Association (MCA) adopted, with minor changes, the service proven Dean pHpump as the American Voluntary Standard (AVS). Subsequently, the American National StandardsInstitute approved the AVS Specifications as national standard B123.1-1971. This standard was laterrevised and approved as ANSI/ASME B73.1M-1984. Dean Series pH pumps continue to meet or exceedthe latest revised B73.1 standard.Dean Series pH centrifugal process pumps are designed to insure long, continuous service life at low cost.Each phase in the production of these pumps is meticulously monitored by an independent quality controldepartment.Pump SizesThe Dean Series pH pump is an end-suction back pull out design regularly available in 22 sizes anddivided 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 Alloy 20. Additional highermetal alloys (Hastelloy B and C, Titanium, etc.) are available upon request. (Standard Materials ofConstruction chart is available on Page 3).Parts InterchangeabilityThe Series pH provides the ultimate in standardization of process pumps. With wide partsinterchangeability among pump sizes, fewer parts are required for inventory. A complete stock of spareparts is readily available from Dean Pump or its network of stocking distributors, thereby reducing shippingtime to a minimum.All Series pH parts, with the exception of the casing (and in some sizes, the impeller), are interchangeablewith the Series pHP Self-Priming Pump.Shaft SealingDean Pump offers a broad line of mechanical seals and standard packing sets to solve the most difficultsealing problems. This feature gives Series pH pumps the versatility to handle a wide range of chemicalservices. A variety of seal chambers such as standard bore, jacketed, large taper bore, and largecylindrical bore are available for specific applications.
