Vertical pumps are constructed from stainless steel, aluminum or cast iron and must be strong enough to withstand internal and external pressures. These pumps are most often used for lifting and transporting water, an application that finds many uses in residential, general purpose, industrial and commercial situations.

Centrifugal pumps are used in wastewater and sewage treatment plants to handle trash and refuse; certain heavy duty models can pump mixtures of solids that are suspended in liquid. As water pumps, vertical pumps are used for deep well pumping and move water from its underground source to buildings for human use or to prevent flooding or drainage issues.

If vertical pumps are made of strong corrosion resistant materials, they are able pump chemicals and acids which is a useful way of transporting hazardous liquids throughout a processing plant.

Vertical centrifugal pumps are simply designed machines. A casing called a volute contains a horizontal impeller mounted perpendicularly on an upright rotating shaft. The electric motor uses its mechanical energy to turn the impeller whose blades impart kinetic energy to the liquid as it begins to rotate up the casing.

Momentum and pressure carry the liquid (most commonly water) through the expanding volute until it exits through a discharge opening, sometimes at high velocities. Vertical pumps are located underground near the source of liquid which they move up to the surface. They are usually electric because a gas tank would be impractical to store and fill. The power cords are kept in a durable protective casing to prevent any leaks or damage.

One example of a vertical pump is an axial flow pump whose impeller is actually a kind of propeller that lifts the liquid in a direction parallel to the pump shaft instead of pushing it in a perpendicular direction like horizontal centrifugal pumps would. Vertical pumps are generally designed in a close-coupled arrangement where the motor and the pump are held in the same slim enclosure that can be lowered into a deep well hole. Another technique is to have the motor at ground level and install the pump underground.

Yes, as of September 20, 2019, National Pump has NSF/ANSI/CAN 61 & NSF/ANSI 372 certification for Vertical and Submersible Turbine Pump assemblies. The deep-set Vertical Turbine Pumps are available in configurations that include either oil-lubricated or fresh water flushed enclosed lineshaft or pre-lubricated open line shaft. The short-set Vertical Turbine Pumps are available in either product lubricated or enclosed linshaft configurations. NPC has certified many optional materials to allow our customers the ability to choose the best materials for their specific application. Whether its standard materials, stainless steel or aluminum bronze, we can meet your needs. Bearings options also include bronze, neoprene, marine or vesconite.

Standard coating is Tnemec N-140 Pota-Pox Plus to provide long-lasting protection of the steel components. The complete pump, from the suction to the discharge, is certified to pump drinking water without imparting chemical contaminants or impurities that can affect our health.

Yes, all pumps that are required to be built to the ISO9001 certification must be manufactured at National Pump’s ISO 9001 certified plant in Glendale, AZ.

National Pump manufactures pumps in a variety of materials to meet our customer’s preference or needs. Bowls and Impellers are available in Cast or Ductile Iron, Cast Steel, Stainless Steel, a variety of Bronzes or Duplex Stainless Steels. Bearing materials are available in Bronze, Marine rubber, and engineered composites.

Every piece of rotating machinery (motor, pump, etc.) has a natural frequency or vibration of operation. As the discharge head of the pump supports the motor, it is the responsibility of the pump manufacturer to design the discharge head to withstand the natural frequencies of the motor through its operating speed range (say 45 – 60 HZ, or 1350 – 1800 rpm). Reed Critical analysis is a calculation that is done that looks at the motor frequency and its effect on the stability of the fabricated head and motor structure. Design adjustments are made to the fabricated head to insure vibration free service. (See story on Tacoma Narrows Bridge failure in 1940)

When using a cast iron discharge head, National Pump Company can only guarantee vibration free operation at full load speed. A cast iron discharge head may be acceptable for operating at reduced speeds if precautions are made by locking-out the operating speed(s) on the VFD IF vibration is experienced from the natural resonant frequency of the motor and discharge head structure. In some cases, modifications can be made to the discharge head to change the resonate frequency of the structure.

Normally catalog performance and efficiencies are ‘best obtainable’ performance derived from testing using standard materials of construction (i.e. Cast Iron Enameled lined bowls & Bronze impellers) with backfilled and highly polished impellers. Any material change or use of a ‘standard’ polish, may reduce pump performance. The Hydraulic Institute sets performance standards and test tolerances for what a manufacturer can or cannot provide. These standards range from – 9% to +16% deviation on Flow, – 7% to +10% on Head, -7% to 0% on efficiency. When specifying a pump, it is important to define early on what your expectations are so that the manufacturer can meet those expectations. Call a National Pump Representative to learn more about the Hydraulic Institute Test Tolerances.

NPSHR is the minimum pressure required at the first impeller of the pump to keep the pump from cavitating (i.e. turning water to water vapor in the pump). This differs from NPSHA (available) which is the absolute pressure at the pump suction. Both values are represented in ‘feet’ of pressure. NPSHA must be a minimum of 3 feet more than NPSHR.
