Single-Stage Horizontal Split Case Pumps
2800 & 5800 Series
- Capacities: 100 to 75,000 GPM
- Heads: 20 to 700 feet
Applications ... Fairbanks Morse single-stage horizontal split case pumps are of rugged, heavy-duty construction designed to successfully operate in a multitude of general liquid pumping and booster applications, and long reliable service with literally zero maintenance costs. These applications can be found in power plants, steel mills, chemical plants, paper mills, refineries, cooling and heating systems and water booster service.
The successful application of horizontal split case pumps requires the consideration of many elements. In addition to knowing the capacity and discharge head requirements, other factors which need to be evaluated include:
- Net Positive Suction Head Available (NPSHA) and submergence
- Capacity operating range
- Horsepower required throughout the pump's operating range
- Suction pressure
Other considerations include:
- Parameters of the liquid being pumped
- Allowable solid size
- Elevation
- Driver requirements
- Material of construction
Features ... Parameters of horizontal split case pumps require the units to be available in either horizontal mounted or vertically mounted configurations to meet user needs. Fairbanks Morse meets these demands by providing horizontal mounted pumps in discharge sizes from 2" to 36" in diameter. Vertically mounted pumps are available in discharges sizes from 3 " to 10" in diameter.
Material of construction include cast iron, bronze, and stainless steel, or other machinable materials. Wear rings for both the casing and impeller are available to provide a renewable surface. Also, renewable shaft sleeves are standard for those portions of the shaft through the stuffing box. Shafts can be sealed with packing or mechanical seals.
Split case pumps are easy to maintain and make it easy to remove the rotating assembly without disturbing the suction or discharge piping. Long bearing life is normal in Fairbanks Morse pumps due to its smooth operation, balanced loading and locked-in-place rotating assembly. Bearings are typically grease lubricated but oil lubrication is a standard option on many units.
Impellers are dynamically and hydraulically balanced, one-piece castings. Their large double suction design virtually eliminates axial thrust loads. Inlet losses are reduced and high suction lifts are capable as a result of this Francis vane impeller design. Extremely smooth contoured passageways provide high efficiency and quite operation.
Horizontal split case pumps can be driven by numerous types of drives including internal combustion engine, steam turbine, or horizontal motors.
