Demanding fluid-handling applications call for the right equipment and expertise

Did you know that we became Georgia’s Viking Pump main distributor over 50 years ago? This is because Viking Pump, Inc. sets the standards for all other gear pump companies and has been an industry leader in the world of positive displacement gear pumps since 1911.

It’s a great partnership.

Viking Pump offers durable products and high-quality solutions for a wide range of demanding fluid-handling applications and processes, and our application engineers have the experience necessary to get the right pump, equipment, accessories, and more for your specific needs.

For example, did you know that positive displacement machines, like pumps or blowers, involve dealing with pressure in a system. The pump or blower has to overcome a system resistance to flow, which is measured in pounds per square inch, or PSI.

However, there are different measurements of PSI. Per our V.P of Sales, Don Layyous:

    • Absolute Pressure is measured relative to a full vacuum.
      The pressure of a vessel completely void of any air molecules would be 0 PSIA,while average atmospheric surface pressure (at sea level) is roughly 7 PSIA.
    • Barometric pressure is measured on weather stations and data buoys using absolute pressure sensors.
      The data gathered by these sensors helps meteorologists track and predict severe weather like hurricanes and typhoons.
    • Gauge pressure is the measurement we use when dealing with equipment.
      It’s measured relative to ambient atmospheric pressure. A vessel completely void of any air molecules (at sea level) would be roughly -14.7 PSIG and ambient air pressure is always measured as 0 PSIG, regardless of whatever current barometric pressure is.

This yields the following formula: P abs = P bar + P ga

“When we are dealing with centrifugal pumps, we deal with head,” says our sales engineer Jim Robinson. “It is used as a measurement to indicate the amount of work the pump has to do to lift a liquid from point A t a higher point B taking into consideration all the friction losses in the pipe."

PSI = Head x S.G


Why Convert PSI to Feet of Head?

Many pump curves (liquid) show head pressure rather than PSIG. Also, if a customer has any vertical lift or pressure or friction loss data, it is sometimes given in feet of water for proper pump sizing. For air piping calculations PSIG is typically used. If a customer requires a friction loss estimate or survey estimate, then available pressure drop data supplied for pipe and fittings is typically found is PSIG.

Do You Have Questions About Your Pump?

Our experts know what they are talking about and have the extensive experience to answer your questions. Whether you need a Viking gear pump, a universal pump, a vane pump, or something else, we are here to help you get the products, equipment and service you need to keep your facilities operating smoothly.
