ubmersible Vertical Turbines


The American-Marsh Vertical Turbine pumps are designed for long, dependable life in many applications. Modern processing methods require modern pumping equipment to satisfactorily handle the many and varied fluids used in the various industries. American-Marsh Engineers, backed by over 125 years of manufacturing experience, have met this demand with the vertical turbines offered today. We have incorporated in our design, ideas and suggestions from competent engineers from all sections of the country.

Bowl Assembly: The pump bowls shall be of close grained, cast iron ASTM A48 Class 30. The water passages on bowl sizes 6” through 16” shall be lined with porcelain enamel or fusion epoxy lined to reduce friction loss, shall be free of blow holes, sand holes and other detrimental defects, and shall be accurately machined and fitted. The impellers shall be of bronze (enclosed or semi-open) and dynamically balanced. Impellers through 16” shall be securly fastened to the shaft with taper split bushings of steel. Larger sizes shall be double-keyed. Impellers shall be adjusted vertically by an external means.
The pump shaft shall be of A582 grade 416 stainless steel, turned, ground and polished. It shall be supported by bronze bearings above and below each impeller. The suction case bearing shall be grease lubricated and protected by a bronze sand collar. The size of the shaft shall be no less than that determined by ANSI/AWWA Specifications E101, Section A4.3 paragraph 4.3.3.
Riser Pipe: The riser pipe shall be sized such that the friction loss wiill not exceed 5’ per 100’ based on the rated capacity of the pump. If possible, the riser pipe should be sized such that the minimum velocity will not be less than 5’ per second at the rated capacity. Riser pipe sections shall not exceed __________ in length. The pipe shall be ¾” tapered (NPT) threaded from material conforming to ASTM A120 or ASTM A53 grade 53.
Maximum water temperature: 85 Fahrenheight.

Minimum flow past the motor: ½ foot per second
Motor Adapter: A motor adapter of close grained ductile iron with rabbeted fits shall be supplied to connect the submersible motor to the bowl assembly. It shall include the motor adapter bearing assembly and a corrosion resistant metal strainer whose free area shall be at least three times the impeller suction eye area. The maximum strainer opening shall not be more than 75% of the minimum opening through the bowl or impeller.
Submersible Motor: The electric motor shall be vertical hollow shaft __________ RPM., three phase (50 or 60 Hz) __________ volts with a non-reverse ratchet, P-base, squirrel cage induction design. Enclosure shall meet NEMA weather protected type type 1 design with stainless steel screens to prevent entrance of rodents. Motor shall have Class B or Class F insulation with temperature rise as specified by NEMA standards for class insulation used and shall have a 1.15 service factor.
Thrust bearing shall be chosen to handle the continuous down thrust as specified by the pump manufacturer with an AFBMA B-10 one-year minimum or five year average life under design conditions. Provisions shall be made for momentary upthrust equal to 30 percent of rated down thrust. The motor rating shall be such that at design it will not be loaded beyond nameplate rating and at no place on the pump curve shall the loading exceed the service factor.
Surface Plate: The surface plate shall be fabricated from carbon steel with a flat face base flange to match the well casing flange, short radius 90 steel elbow terminating in a 150 pound raised faced steel discharge flange. The surface plate shall be fitted with properly sized electrical junction box to allow for splicing surface cables and well cables. It shall also be tapped from a well vent and air-line and shall be provided with lifting lugs of sufficient strength to lift the entire pump and motor assembly including riser pipe. A short 12”, threaded or flanged, nipple shall extend below the surface plate for connection to riser pipe.
Power Cable: The power cable shall be sized such that the voltage drop will not exceed five percent at the motor rated full load current and voltage. Cable shall be designed specifically for submersible pump service and shall consist of either three single conductors individually insulated or three individual conductors individually insulated and the whole covered with an outer jacket.
