ANSI Pump Types

ANSI is an acronym used to describe the American National Institute Pump Standard. The standard evolved from the American Voluntary Standard (AVS) that was first proposed by the Manufacturing Chemists Association in the nineteen fifties. It is a set of inch dimensional standards that describe the envelope dimensions of a back pull out, centrifugal pump: The location of the pump hold down bolts; the distance between the suction and discharge port centerlines; and the height of the shaft on the drive end.There are currently three overall standard pump lengths: 17.5 inches; 23.5 inches; and 33.875 inches.

Features: 

• Pumps of the same size are drop-in replacements dimensionally regardless of the manufacturer. Hydraulically the pumps may differ slightly.
