- Effects of Liquid Viscosity on Rotodynamic (Centrifugal and Vertical) Pump Performance
- Pump viscosity corrections
HI is a pump association of positive displacement and rotodynamic, centrifugal pump manufacturers and suppliers.
HI standards cover pump design and applications, installation, operation and maintenance, pump testing, definitions
and nomenclature and address such topics as allowable vibration, pump efficiency, nozzle loads, pump piping,
viscosity correction and more.
Applied Flow Technology first joined HI back in 2005 as an associate member. Today, our participation includes:
This standard defines the preferred operating region (POR) for rotodynamic pumps based on pump specific speed. Additionally, factors that are considered in the setting of the allowable operating region (AOR) are detailed, and the effects of operating away from the pumps best efficiency point (BEP) are discussed. This standard applies to all rotodynamic pump and markets. It aids the specifying engineer and pump system designer to design a design the system and select pumps that will operate efficiently and reliably.
