PERFORMANCE ENGINEERED TO YOUR APPLICATION
 
Sizes
English pump sizes from 8 through 36 inches; Metric models from 600-1400 millimeters. Other sizes available for special applications.
 
Materials of Construction
Cast Iron, 304 or 316 Stainless Steel, CD-4MCu, Ferralium, Alloy 20, UHB 604L, Nichel, Monel, Hastalloy, Titanium and other to suit application.
 
Configurations
Horizontal single or double elbow, and special designs. Flow in either direction. Guide vanes available. Base mounted and pipe-suspended models.
 
CAST ELBOW DESIGN
 
EAF pumps using cast-elbow construction are available in 10 through 54-inch sizes. The unit shown is on a short base designed for solid mounting to a concrete foundation. When solidly mounted bases are used, pipe expansion joints must be used to compensate for heat induced dimensional changes of piping system.
 
ESEAF and EMPAF SINGLE ELBOW AXIAL FLOW PUMPS
 
Eagle offers two single elbow axial flow pump models: the SEAF and the MEAF. The hydraulics, most mechanical features and options, and basic design philosophy for both models are similar. Their differences are primarily in mounting technique.
 
IMPELLER and HYDRAULIC DESIGN
 
Eagle EAF Pumps are available with any of several impeller designs. All are precisely balanced and keyed to step-fit shaft for ease of removal and reassembly Pumps may be ordered for either top or end suctions.
 
ELBOW CONSTRUCTION
 
Both SEAF and MEAF pumps are offered with cast or fabricated elbows. Flanges are available in several pressure ratings according to A.S.M.E. Section VIII standards. To reduce expenditures for replacement parts and cut maintenance time, all EAF pump sizes are available with separate casings and/or replaceable liners.
 
FABRICATED ELBOW DESIGN
 
Large MEAF pumps are generally constructed using fabricated elbows. The unit illustrated features a separate casing surrounding the impeller; oil lubrication with an oil distribution wheel for positive circulation to the thrust bearing; and is to be suspended from piping, eliminating the need for a pump base. The MEAF is offered in a full range of sizes and material of construction.
 
BEARING and SHAFT ASSEMBLIES
 
Heavy duty shafts are fully cantilevered into pump elbows. Eliminating the need for internal bearings. Split bearing housing simplify maintenance. Grease or oil lubrication is available on pumps 24-inches and below; larger models are oil-lubricated only. Available on 8-24 inch MEAF sizes, back pullout permits rapid removal of the pump rotating assembly without disconnecting any portion of the piping system.
 
 
Type: SEAF
Type: MPAF
 
SEAF with FABRICATED ELBOW
 
Fabricated elbows are available on 30-inch and larger SEAF pumps. Pump is shaft-driven by an independently mounted motor.
 
STUFFING BOX
 
Large stuffing boxes contain 5 rings of packing. Mechanical seals, water cooled glands, and inflatable shaft seals are also available.
 
PUMPING and DRIVE MOUNTING
 
SEAF and MEAF pumps are available with custom designed bases for complete pump, motor and drive systems as illustrated on these pages. Bases may be rigidly mounted to the plant floor, with expansion joints mounted on pump flanges, or maybe sprung-mounted. Eagle spring bases assure that the pump remains level, regardless of vertical movement due to pump expansion.
 
MEAF pumps are specifically designed for pipe-suspended mounting. This technique automatically compensates for pipe expansion, simplified installation, and reduces costs. Pipe-suspended mounting also eliminates shaft misalignment caused by undue piping forces and moments. Small MEAF pumps may be driven by a suspended motor.
 
MPAF with CAST ELBOW
 
Although illustrated as a pipe-suspended designed, the MEAF may also be mounted on conventional or spring basis using the attachment feet shown in dotted lines.
 
DIMENSIONS
NOTE: Flange thickness ("T") are not shown in the tables since dimensions depend upon nominal operating pressures specified. All flanges are according to ASME. Section VIII.
 
Flange drilling is standard ANSI 150 lbs. On English pump sizes and standard NP 10 on matric units. Special drilling on request.
 
The products shown should not be operated without safety devices prescribed by applicable laws and regulations.

Construction details and dimensional data are for general information only and are subject to change without notice.
