Oil Fuel Pump Sets Guidelines

Viking Pump provides these guidelines about Fuel Oil Pump Sets for your information. Pump configurations will vary from application to application. For example, pump options may include relief valves, mechanical seals, steel-fitted construction, carbon bushings, and jacketing to name a few. Drives may vary as well, from direct drives to gear reducers or V-belts.

Slower speeds, lower pressures, and materials designed for the anticipated temperature will pay off in longer trouble-free service, even if oil properties vary from those originally anticipated. Simple do’s and don’ts of oil fuel pumping include:

Do’s and Don’ts

  • Install the pump as close as possible to the supply tank.
  • Leave working space around the pumping unit.
  • Use large, short, and straight suction piping. “Short and fat” pipes are excellent.
  • Install a strainer in the suction line.
  • Double-check alignment after the unit is mounted and the piping is hooked up.
  • Provide overpressure protection for the discharge side of the pump, either in-line or on the pump.
  • Extend service life with preventive maintenance procedures such as periodic lubrication, adjustment of end clearance, and examination of internal parts.
  • Obtain, read, and keep the maintenance instructions furnished with your pump.


  • Run a pump at faster than approved speeds.
  • Run a pump at higher than approved pressures.
  • Run a pump at temperatures at higher than approved temperatures.
  • Use extra large, extra long suction line with a suction lift.

Installing a vacuum gauge and a pressure gauge on or near the pump will also help lengthen service life. Gauges provide a window into what is happening inside the pumping system. Properly interpreted readings can give clues to the nature of many problems. Long-term readings will show gradual changes taking place within the system.

Given the availability of certain fuels at any particular time, many fuel oil systems now accommodate No. 2 through No. 6 fuel oils. Each fuel oil differs slightly in properties and these differences place unique demands on the system.
