ANSI Pumps

An ANSI pump can be defined as an overhung impeller, end suction, single stage, centerline discharge, centrifugal pump. ANSI pumps can be both horizontal and vertical designs.

This type of pump is so designated as an ANSI pump because it fits the dimensional and operational criteria and requirements of the ASME B73 – 1991 pump specification.

Some important dimensional criteria include the following: Centerline height, Footprint, Overall length, Pump sizes (Suction x Discharge x Nominal Impeller Diameter)

ANSI pumps are covered by a standard that requires all such pump types to be dimensionally interchangeable and to have certain design features to facilitate installation and maintenance. This standard requires that all ANSI pumps, regardless of the pump manufacturer, be interchangeable with respect to mounting dimensions, size and location of suction and discharge nozzles, input shafts, baseplates, and foundation bolt holes, etc.

Therefore, the ANSI pump standard provides a good minimum set of requirements when purchasing new pumps.

Pumps are commonly rated by horsepower, flow rate, outlet pressure in feet of head, inlet suction in suction feet of head. The head can be simplified as the number of feet the pump can raise or lower a column of water at atmospheric pressure.

Submersible pumps are used for a variety of jobs, including pumping out flooded basements, pools, spas, ponds, pits, sewage and solids removal, and a lot more. We have a variety of industrial/commercial grade submersible pumps, as well as, contractor grade suited for the homeowner.
