Slurry Pumps: Sizing and Power Requirements

Slurry to be pumped
Flowrate (m3/Hr)
D50 size solids (microns) D50 is the screen opening size at which 50 percent of the solids pass through the screen.
% Solids by weight (%)
% Solids by volume (%)
Solids specific gravity
Acceleration by gravity (m/s2)

 

Slurry Velocites in Pipe
Actual Velocity (m/s) Pipe diameter must be selected so actual velocity is slightly higher than critical velocity.
Critical Velocity (m/s) 0

 

About the Piping:
C (Hazen-Williams) value Rough Pipe, C=100 Very Smooth Pipe, C=140
Pipe ID (m)
Pipe equivalent length (m)
Pump intake elevation (m)
Pipe discharge elevation (m)
Pressure at discharge (PSI)

 

Calculated Head Losses
Static Head (m) 0 The friction calculation is based on Hazen-Williams formula
Head Loss - Friction (m)
Pressure Head (m)
Total Head (m)
0

 

Pump Information
Assumed Pump Efficiency (%)
Pump Motor Power (kW)
Approx Impeller Tip Speed (m/min) 60 Tip speed< 1400 is OK; if > 1600 too much wear
