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 140 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 pumpmanufacturers 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 140years, American-Marsh Pumps products have

provided cost effective solutions by buildingpumps to last. Durability by design is always themost cost effective solution. From engineeringand design to final assembly, experienced peoplecontrol each step of the manufacturing processwith 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 qualitypump products for over 140 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.

Casing: The casing is constructed of high tensileASTM A48 cast iron or other specified material. It isof the volute type, carefully and accurately propor-tioned to permit smooth flow and to convert highvelocity energy of the fluid as it leaves the impellerinto pressure. Model NCC, NCCC & NCV pumpsfeature a fully casted suction elbow with base. Anoversized, oval cleanout plate is located on the suc-tion eldow to provide visibility and accessibility tothe impeller vanes. Model NCH pumps feature afully casted suction cover with an oversized, ovalcleanout plate to provide visibility and accessibility tothe impeller vanes. The suction nozzle is removablefor inspection and can be replaced if severly worn.The discharge nozzle is casted integral with thevolute and is of 125 psi dimensions. An oversized,oval cleanout plate is located on the dicharge nozzleto provide visibility and accessibility to the impellerblades and casing cutwater. Casing wear plates can besupplied as an option to extend casing life. Necessaryvent and drain openings are provided.

Impeller: The impeller is of the high efficiency,enclosed, two vane end suction type, casted in onepiece of ASTM A48 cast iron or other specifiedmaterial. All impellers are hydraulically and dynami-cally balanced prior to assembly and all impellers havefront and rear pump out vanes standard to reducematerial from building up in front of or behind theimpeller. The impeller features rounded tips to pro-vide a smooth surface around which stringy and“limp” materials will readily flow. The balanced twovane design also eliminates excessive and undesirableweight which can affect shaft, mechanical seal andbearing life. All impellers feature large spherical solidspassing capability with larger models capable of pass-ing seven (7) inch solids. Large diameter impellersalso allow for higher head applications at lowerspeeds which is preferable when moving fluid withlarge solids present.

Stuffing Box/Mechanical Seal Chamber: Thestuffing box/mechanical seal chamber is constructedof high tensile ASTM A48 cast iron or other speci-fied material. The boxes and chambers are designedto house packing with an lantern ring, componentand/or cartridge mechanical seals. The boxes andchambers also feature an Accu-Shockbushing thatprevents major shaft deflection and bearing damagefrom rocks or other heavy objects entering theimpeller. This is a standard feature not found inother pumps of this type.

Shaft: The shaft is of high strength 420 stainlesssteel, ground to accurate dimensions and polishedto a smooth surface. It is designed for extra stiffnessto avoid all critical speeds during operation. The fluid end of the shaft is tapered to allow for easy removal during inspection and maintenance. The shaft is protected by a shaft sleeve of amplethickness to ensure long life and can be supplied in various materials.

Power Frame: The power frame is constructed of high tensile ASTM A48 cast iron and providessupport for the inboard and outboard bearings. Theoutboad bearing is of the deep grove, single rowtype designed to carry all radial loads encounteredby the pump. The inboard bearing is of the deepgroove, double row type designed to carry all axialthrust loads encountered by the pump. This inboard double row bearing is also designed to minimizeshaft deflection at the mechanical seal extendingmechanical seal life. All bearings are sized to maintain a minimum of 50,000 hour bearing life.Each bearing housing is sealed from water leakageby the use of an oil lip seal and are grease lubricat-ed. NCH models are designed for flex-coupled ser-vice. NCC & NCV models are designed with thefull power frame but also include a C-face bracketfor close-coupled operation.
