Vertical Turbine & Propeller Pumps
We have partnered with global leader in vertical turbine and propeller pumps Fairbanks Morse in order to bring you the latest technology to improve your
Vertical Turbine Pumps
These pumps have wide head ranges and bowls up to 57″ (1447.8 mm). They are ideal for applications where surface equipment is prohibited, or where there are sound restrictions such as in parks or residential areas.
Turbine Bowl Assemblies
- Bowl Castings are manufactured of heavy-duty, high-quality cast iron, and feature a minimum 30,000 PSI (2068.9 Bar) tensile strength, with smooth passages designed for efficient operation. Optional coated passages can also be used to further increase pump efficiency.
- Enclosed Impellers are precision-cast, matched to the pump bowls and are dynamically balanced to avoid vibration. A top shaft adjusting nut (or adjustable coupling) makes it easy to adjust impeller-to-bowl clearance.
- Suction Bearings are grease-packed and fitted with a sand collar to keep grit and other abrasives out of the bearing life, ensuring long life.
- Cast Iron Suction Bell with integrally cast guide vanes provides a smooth flow into the first stage impeller and reduces the formation of vortexes, further contributing to efficient operation.
- Bowl Bearings are lubricated with the liquid pumped and assure accurate shaft alignment.
- Renewable Impeller and Bowel Wear Rings (optional) allow you to restore a worn and inefficient unit to near original condition, extending operation for many years.
- Connector Bearings are lubricated with water, oil, or grease, depending upon the lubricant used in the enclosing tube. Connector bearings are employed when an enclosed lineshaft is used.
Axial Flow Propeller Pumps
These pumps from Fairbanks Morse are designed for high volume fluid movement at low discharge pressures. Used extensively for pumping water from lakes, cooling ponds, tanks, rivers and oceans, typical applications include raw water intake, de-watering, storm water removal and flood control. Fairbanks Morse vertical axial flow propeller pump applications are found in a variety of markets including urban and rural municipal water, government, industrial and irrigation, and more.
Axial and Mixed Flow Bowl Assemblies
Mixed flow pumps are very similar to axial flow pumps; however, they impart a radial motion and swirling momentum to fluid as it moves through the rotor section. Axial and mixed flow bowls have small footprints, so they are used widely in residential wells, municipal water works, and industrial applications.
- Bowls are heavy-duty cast iron with smooth passageways to increase efficient operation.
- Intermediate And Discharge Bowl Bearings are product-lubricated and designed to carry extreme loads for maximum service life. The suction bowl bearing is grease-packed and fitted with a sand collar to keep out sand and grit.
- Suction Bell reduces vortexing and entrance losses through three or four integrally-cast guide vanes to keep passages clog-free.
- Discharge Diffuser Vanes provide a smooth flow entering the discharge column.
- Axial Flow Propellers have well rounded leading edges, a design feature that keeps stringy materials from accumulating and increases solids-handling abilities.
- Mixed Flow Propellers also feature well rounded edges and a hydrofoil design to help large diameter solids pass. All propellers are dynamically balanced to eliminate vibration.
- Bowl Shafts have large diameters needed to transmit the required drive torque.
- Bowl Liners provide a renewable wear surface and maintain the clearance between the propeller and bowl. Replacement of bowl liners restores worn units to their original condition.
Vertical Mixed Flow Pumps
These pumps are typically used wherever a moderate volume of liquid needs to be pumped upward at moderate pressure. The advantages of mixed flow pumps include minimum footprint, no priming required (because the pump bowl assembly is submerged), and Net Positive Suction Head Available (NPSHA) at the lowest level to satisfy the NPSHA requirements of the pump. In addition, vertical mixed flow pumps are easily adaptable to various design codes, can be modified for changing hydraulic conditions, and generally experience less wear due to the lower operating speeds they require.
Constructed of rugged cast iron to meet sanitary requirements and support the column, lineshaft, and bowl assemblies, discharge heads can accommodate any drive source. Large openings make it easy to access the stuffing box or mechanical seal, and smooth passageways keep friction low and operation efficient. The integrally-cast discharge flange can be either a 125 lb. (56.999 kg) or 250 lb. (113.4 kg) design.
The discharge head is designed to be adaptable to threaded or flanged column. Additional features include the following:
- Soleplates made from cast-iron or steel are used to mount the discharge heads. Once the soleplate is leveled and grouted in place, the pump can be removed for maintenance and then reset without realignment.
- Fabricated Discharge Heads are formed from high quality steel, with the discharge either a flanged or plain-end design. The flanged discharge is available through 300 lb. (136.08 kg). The three-segment elbow design smooths the fluid flow and reduces friction losses, increasing efficiency.
- Water Flush Lubrication allows an external water source to flow through the shaft enclosing tube to lubricate lineshaft bearings. A renewable wear sleeve protects the shaft throughout the stuffing box area, and packing or mechanical seals are used to seal the shaft.
L Type Discharge Heads
- L-Type Fabricated Discharge Head is designed to accept the column, shaft, and bowl weight as well as the hydraulic thrust. Formed from high quality steel, heads are gusseted for a rigid base to eliminate vibration and maximize smooth operation.
- Shaft Sealing can occur using the most mechanical seals. When mechanical seals are used with a vertical solid shaft driver, a spacer coupling is required to simplify seal maintenance and replacement.
- Two-Piece Top Shaft Construction is supplied for ease of vertical solid shaft driver removal.
- Underground Discharge Elbows are fabricated from high quality steel, and available with either flanged or plain-end discharge. The center-line of discharge may be located any distance below grade.
- Fabricated Steel Pedestal serves as the mounting base for the driver, and provides access to the stuffing box or mechanical seal area. Air release connections are provided above the base plate.
- Packing Box is product-lubricated and available through 400 PSI (27.586 Bar). A leakage drain connection is provided in the head to eliminate liquid build up in the packing box.
Column And Lineshaft Assemblies
With an open lineshaft design, the fluid being pumped lubricates the shaft bearings. With an enclosed lineshaft, external water flush, oil, or grease-bearing lubrication can be used. Column connections are ranged for ease of maintenance.
- Threaded Steel Discharge Column is available in standard sizes through 14″ (355.6 mm) diameter. Where greater strength or ease of assembly and disassembly are required, a flanged column pipe is also available in these sizes. A welded flanged column is supplied as standard in column sizes 16″ (406.4 mm) and larger.
- Alignment is maintained on enclosed lineshaft applications by butting the pipe together within the sleeve-type pipe coupling. When an open lineshaft is used, pipe ends are butted on the bearing retainer flange.
- An Enclosing Tube is used to protect the lineshaft and bearings from the fluid being pumped. Lubricants can be oil, grease or water flush. Note that interchangeable sections in five feet lengths (1524 mm) have machined ends with bronze connector bearings. Deep set turbines with an enclosed lineshaft utilize a tube stabilizer approximately every 50 feet (15.24 m) of setting.
- The Lineshaft is precision-ground, high tensile strength steel with an extra strong threaded coupling. Shaft size and bearing spacing are determined by horsepower and thrust requirements.
- Neoprene Spiral Grooved Rubber Bearings are used in open lineshaft configurations through 14″ (355.6 mm) and are held in place by bearing retainers, allowing the shaft and renewable shaft sleeve to rotate. In 16″ (406.4 mm) column and larger sizes, a spider/bearing hub is welded in place just below the upper column flange.
Pot Pumps and Submersible Turbines
In situations where NPSHA is low, in high pressure systems, where suction pressures are variable and/or critical, or where differences in the elevation of suction and discharge piping are needed, vertical turbine pumps can be incorporated with a “pot” or “can”. Pot pumps are frequently used in pipeline (in-line), water booster, boiler feed, condensate, product loading and unloading, and volatile liquids handling applications.
Pot pumps are designed to accommodate different discharge head and pot configurations, and to allow suction and discharge locations above- or below-grade. Featuring a compact design with minimal footprint, pot pumps allow the turbine suction bowl to be submerged for proper NPSHA. Discharge heads are sealed to the pot flange in order to accommodate temperature and pressure demands.
Bowls can be staged to meet hydraulic requirements. The discharge head can be of “C”, “D”, “L”, or “T” type designs.
Submersible turbine units perform with the same hydraulics as lineshaft turbines and are used in deep-setting, high head applications where the practical limits of long drive shafts and multiple shaft bearings are exceeded.
Submersible turbine units are also used where dust fumes, high/low temperatures, etc., might adversely affect driver or discharge head sealing. Submersible turbines are also used when the pump needs to be installed horizontally.
Submersible turbines are driven by a submersible motor coupled directly to the bowl shaft. Discharge piping requires only a simple discharge elbow at the discharge surface. There is no packing box or mechanical seal to maintain. Power to the motor is conducted via a water-proof cable.
