Vertical Lube Oil Pumps

By Flow-Tech Industries

The vertical turbine pump has been specified for difficult or unusual applications, such as limited floor space, reduced operating noise levels, high efficiency, high discharge pressures and unusual suction conditions as required for low NPSH.

Applications – For the Industrial Process, Agricultural, Utility, Petroleum, Petro-Chemical, Municipal Water Supply and Water Treatment markets

For more than a century, Layne/Verti-Line has been one of the leaders in the industry, constantly improving designs to satisfy changing market requirements.

Layne/Verti-Line vertical turbine pumps are designed primarily for heavy duty, continuous operation, in municipal and industrial applications.
The average installation can expect extra-long trouble-free pump life.

Fairbanks Morse vertical turbine pumps are of rugged, heavy-duty construction designed to successfully operate in a multitude of applications such as pumping from water source including wells, lakes, cooling ponds, tanks, rivers and oceans.

These applications include raw water intake, liquid transfer, cooling water circulation, booster service, storm water, flood control, marine, process services, volatile fluids, condensate, fuel pumps and mine dewatering. Fairbanks Morse vertical turbine pump applications are found in a variety of markets including: urban and rural municipal water, irrigation, chemical processing, primary metals, petroleum, power plants, mines, food processing, offshore platforms, and more.

The successful application of vertical turbine 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:

  • Total pump thrust
  • Net Positive Suction Head Available (NPSHA) and submergence
  • Allowable bowl pressure
  • Allowable pump shaft stretch
  • Horsepower required throughout the pump’s operating range
  • Allowable discharge head hanging weight
  • Sump requirements

Other considerations include:

  • Parameters of the liquid being pumped
  • Allowable solid size
  • Type of line shaft lubrication
  • Type of line shaft sealing
  • Elevation
  • Driver requirements
  • Materials of construction

Parameters of vertical pumping applications require the units be available in a variety of pumping configurations to meet user needs. Fairbanks Morse meets these demands by providing pump bowls from 4″ to 57″ in diameter. Turbine bowls can be staged in series to produce the necessary discharge pressures.

Materials of construction include cast iron, bronze, and stainless steel, or other machineable materials. Wear rings are available to provide a renewable surface.

Open line shafts allow the product to lubricate the shaft bearings. Enclosed line shafts can provide external water flush, oil, or grease-bearing lubrication. Threaded or flanged column and line shaft assemblies are available in both short and deep-set applications.

Drive shafts extending through the discharge head can be sealed using either packing or mechanical seals. A wide range of mechanical seal designs are available along with an assortment of packing box designs, including those for high-pressure applications. Fairbanks Morse also offers an array of discharge head designs, including cast iron or fabricated steel construction, above-or below-ground discharge, and flanged or plain-end discharge connections.

Vertical pumps require a minimum of NPSH since the lowest impeller is submerged in the liquid. However, even when the system design does not provide enough NPSH, vertical turbine pumps can be supplied with its own reservoir or “pot”. In this way, submergence required by the first stage impeller can be achieved to ensure reliable performance.

Vertical turbine pumps can be driven by vertical hollow-shaft motors, vertical solid-shaft motors, or through right-angle gears by an internal combustion engine, steam turbine, or horizontal motor. When vertical hollow-shaft drivers are used, impeller-to-bowl clearances can be maintained with an adjusting nut located at the top of the driver. When vertical solid-shaft drivers are utilized, impeller clearance is regulated with an adjustable coupling.
