Description
Horizontal end-suction centrifugal pump for chemical process service (commonly called ANSI pump).
Applicable Standards (5)
ASME — 2 standards
ASME B73.1
Specification for Horizontal End Suction Centrifugal Pumps for Chemical Process
Horizontal end-suction chemical process pumps (often called ANSI pumps).
Key requirements (6)
- Horizontal end-suction centrifugal chemical pumps with dimensional interchangeability.
- 10 standard frame sizes (AA through A105) with fixed dimensions (suction/discharge sizes, footprint).
