Description

This standard covers types and nomenclature, definitions, design and application, installation, operation and maintenance, and test of sealless rotodynamic pumps driven by canned motors or magnetic couplings.

Not included are submersible wastewater pumps that do not have external shaft seals and are therefore not susceptible to external shaft leakage. Deep well submersible pumps are also excluded.

ANSI/HI 5.1-5.6-2010 is designed to provide users with information necessary to define and describe the construction features and benefits of using sealless pumps and contains a number of significant updates and enhancements. They include: pump part names and definitions, magnetic temperature limits and motor insulation temperature limits, magnetic drive pumps mounting specifications, and new monitoring device information. In addition, the standard provides users with expanded information in the test sections that cover types of tests, parameters, procedures, and acceptance criteria.
