American-Marsh Pumps, one of the oldestpump lines in America, are pump productssteeped in heritage. Since 1873, the American-Marsh line of pumps has withstood the test oftime. During the last 130 years, over 100 vari-eties of pumps have been designed and built.From steam pumps to centrifugal pumps,
American-Marsh pumps have been built tomeet the ever changing requirements of society.Over the last century through continuous prod-uct development, more American-Marsh mod-els have been retired than most other pump
manufacturers have ever produced. Hundredsof thousands of pumps have been made, alldesigned for longevity, allowing many of themto continue servicing customers over 50 years.
All of our pumps have three superior charac-teristics; Design, Performance, and Durability.Our engineering department, which includes anin-house pattern shop, designs each pump sothat installation and maintenance is easy. Ourperformances are engineered to meet or beatthe competition in each category. For 130
years, American-Marsh Pumps products have
130 Years of Pump Manufacturing
provided cost effective solutions by building
pumps to last. Durability by design is always themost cost effective solution. From engineeringand design to final assembly, experienced peoplecontrol each step of the manufacturing process
with quality control inspections performed ateach step. All pumps shafts are heat straight-ened. All impellers are computer balanced.Pump testing is done in our new state of the arttest facility. All of these factors ensure youreceive consistent quality product every time.
American-Marsh Pumps has provided quality
pump products for over 130 years. AtAmerican-Marsh Pumps, we know that long lifeand superior performance are the keys to satis-fied customers. By understanding your needs,
we can design products that meet those needs.Our product family reflects years of customerinput, product upgrades, redesign and newproduct development, all focused on meetingand exceeding your expectations.

Bowl Assembly: The pump bowls shall be of closegrained, cast iron ASTM A48 Class 30 or other specifiedmaterial. The water passages on bowl sizes 6" through 18"shall be lined with porcelain enamel or fusion epoxy linedto reduce friction loss, shall be free of blow holes, sandholes and other detrimental defects, and shall be accuratelymachined and fitted. The impellers shall be of bronze(enclosed or semi-open) and dynamically balanced.Impellers through 18" shall be securely fastened to theshaft with taper split bushings of steel. Larger sizes shall bedouble-keyed. Impellers shall be adjusted vertically by anexternal means. The pump shaft shall be of A582 grade416 stainless steel, turned, ground and polished.
Strainer:A basket or conical type strainer shall be pro-
vided having a net inlet area equal to at least four timesthe suction pipe area. The maximum opening size shallnot be more than 75% on the minimum opening of the
water passage through the bowl and impeller.
Column Assembly: The outer column pipe shall be 5"and larger of ASTM A53 grade B steel pipe of ASTM
A120 in interchangeable sections not over 10' in lengthfor 1800 RPM and 5' in length for 2200 RPM and above.Maximum runout in 10' shall not exceed 0.005". Columnpipe may be supplied in a threaded or flanged configura-tion. Top and bottom sections of column pipe on productlubricated pumps shall not exceed 5' in length.
The lineshafts shall be provided with ASTM A269 grade304 stainless steel threaded sleeves at the location of eachlineshaft bearing. Bearing spacing shall not exceed 10' for1800 RPM and 5' for 2200 RPM and above.
Discharge Head: The discharge head shall be of closegrain, cast iron, ASTM A48 class 30, free of sand holesand other defects, accurately machined and with a surfacedischarge. Discharge flange shall be machined and drilledto ANSI standards for 125 lb. rating. The top of the dis-charge head shall have a rabbet fit to accurately locate the
vertical hollow shaft driver, and have a diameter equal tothe drive base diameter (BD).
An optional fabricated steel discharge head of schedule40 fabricated steel can be supplied. The fabricated steeldischarge head shall be accurately machined with an aboveground or below ground discharge. Discharge flange shallbe machined and drilled to ANSI standards. The top ofthe discharge head shall have a rabbet fit to accuratelylocate the vertical hollow shaft driver, and have a diameterequal to the driver base diameter (BD).
For barrel applications, a T discharge head can be sup-plied. The discharge head shall be fabricated of carbonsteel materials using ASTM A181 flanges, ASTM A53grade B body pipe and ASTM A36 steel plate with the
suction and discharge flanges inline with each other andlocated 180 apart, or as specified. The suction and dis-charge flanges shall be machined and drilled to ANSIraised face standards with bolt holes straddling dischargecenterline.
For submersible applications, the surface plate shall befabricated from carbon steel with a flat face base flange tomatch the well casing flange, short radius 90 steel elbowterminating in a 150 pound raised faced steel dischargeflange. The surface plate shall be fitted with properly sizedelectrical junction box to allow for splicing surface cablesand well cables. A short 12", threaded or flanged, nippleshall extend below the surface plate for connection to riserpipe.
Stuffing Box: The seal arrangement provided shall beone of the following (packing or mechanical seal):
The standard cast iron stuffing box shall be rated for 125PSI discharge pressure and shall be fitted with graphiteacrylic packing. It shall have a lantern ring or greasechamber placed as required below the top packing ring.Throttle bearing shall be bronze with stainless steel bolt-ing and with brass or stainless steel adjusting nuts. Sealingbetween the stuffing box and the discharge head shall beaccomplished by means of an o-ring.
A unit which requires a mechanical seal shall have ahousing bolted to the head with an o-ring seal. The hous-
ing shall have a lower bronze throttle bushing. The hous-ing seal chamber shall accommodate a single sleeved (bal-anced/unbalanced) mechanical seal suitable for the maxi-mum pressure developed by the pump and temperature ofthe pumped fluid. Seal materials shall be compatible withthe liquid pumped.
Motor: The electric motor shall be vertical hollow shaftor vertical solid shaft, three phase (50 or 60 Hz), a non-reverse ratchet, P-base, squirrel cage induction design.Enclosure shall meet NEMA weather protected type 1design with stainless steel screens to prevent entrance ofrodents. Motor shall have Class B or Class F insulation
with temperature rise as specified by NEMA standards forclass insulation used and shall have a 1.15 service factor.
Motor Adapter (Submersible):A motor adapter ofclose grained ductile iron with rabbeted fits shall be sup-plied to connect the submersible motor to the bowlassembly. It shall include the motor adapter bearingassembly and a corrosion resistant metal strainer whosefree area shall be at least three times the impeller suctioneye area. The maximum strainer opening shall not bemore than 75% of the minimum opening through thebowl or impeller.

BOWL ASSEMBLY
Bowl assemblies are constructed of heavy wall class 30 cast iron.All impellers, both enclosed and semi-open, are constructed withheavy vanes and shrouds for long life. Diffuser bowls through 18"diameter have a standard vitreous enamel coating on the interiorto increase efficiency and durability in aggressive applications.
Bowl assembly shafts are standard 416 stainless steel and impellersthrough 18" are colleted standard (larger sizes are keyedstandard). The suction case has a grease packed bearing with sandcollar standard.
DISCHARGE CASE
The discharge case is constructed of heavy duty ductile iron. On
enclosed lineshaft construction, two lip seals and two flush portsare provided standard for long life and durability. Additional vanesare employed for minimizing friction losses of the fluid as it leavesthe bowl assembly.
STRAINER
Optional strainers can be supplied in a conical, basket or vortexsuppressor configuration. These strainers can be supplied ingalvanized steel, bronze or stainless steel.
COLUMN ASSEMBLY
The column assembly is constructed of heavy wall carbon steel.This assembly can be supplied in an open or enclosed lineshaftconfiguration. All shafting is heat straightened and bearings arespaced at appropriate intervals to minimize vibration and to extend
pump life. Lineshaft bearings have helical grooves to ensure uniformlubrication. The overall length of the pump can be engineered tomeet the customers specifications.
