4.7 Forces and Moments at Nozzles
Below are the allowable combined branch loads applicable for all GIW slurry pumps.
Methods based on ANSI/HI 12.1-12.6-2011 Slurry Pump Standard. Loads generally
exceed HI/ANSI 9.6.2-2008 table 9.6.2.1.4a and API 610-2004, Table 4. Higher
allowable loads may be possible depending on individual pump configuration and
operating conditions. Contact your GIW / KSB Application Engineer for more
information.
NOTE: Discharge branch coordinate system always moves with the branch angle.
(Fz is always along the direction of flow).
