Draft Scope/Description:

1. Scope

1.1 Inclusions

This Standard is intended for industrial slurry pumping systems with the following characteristics:

i.    Electrically driven single and multi-stage slurry pumps
ii.   Flowrate greater than 7 L/s
iii.   Average particle size (d50) between 50 microns and 8 mm
iv.  Settling slurry
v.   Slurry behaving as a viscous Newtonian fluid (shear stress is linear and proportional to velocity gradient)
vi.  Two-phase (liquid and solid) or three-phase (liquid, solid and air) slurries
vii.  Any viscosity
viii.  Slurry pumping systems with total pipe length less than 100 meters. For longer pipe length see clause 5.4.2

1.2 Inclusions

This Standard is not intended to be used for pumping systems with the following characteristics:

i.  Slurries with transport fluid other than water.
ii.Gravel and dredge pumpage (average particle size greater than 8 mm).
iii. Non-settling particle in concentrations that lead to a non-Newtonian slurry

1.3 Terminology

 

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
