PARSIPPANY, NJ – The Hydraulic Institute has updated the 2000 edition of the ANSI/HI standard on sealless centrifugal pumps and published ANSIHI 5.1-5.6 – 2010 Sealless Rotodynamic Pumps for Nomenclature, Definitions, Application, Operation and Test. The revised standard covers sealless rotodynamic pumps driven by canned motors or through magnetic couplings with conventional motors.

The Hydraulic Institute has also updated its standard ANSI/HI 4.1-4.6 – 2010 Sealless, Magnetically Driven Rotary Pumps. This standard covers the unique features of these pumps and includes sections on types and nomenclature; definitions; design and applications; installation, operation, and maintenance; and testing of these pumps.

Additionally, the Hydraulic Institute has updated the ANSI/HI Standard for Rotary Pump Tests version 2000 and has introduced ANSI/HI 3.6 – 2010, Rotary Pump Tests. This updated standard applies to industrial/commercial rotary positive displacement pumps and includes detailed procedures on the setup and methods for conducting hydrostatic test and performance tests of such pumps.
