Know The Basic of Slurry Pumping

Slurry can be really tough on pumps! Being thick, abrasive & with high specific gravity, slurry is one of the most challenging fluids to move. 

 

What is slurry?

Slurry is a mixture of solids and liquid, generally water. The particles can be both abrasive & non abrasive, although abrasive particles are very much common. The purpose to move slurry can be transporting as much solids particles as possible, hydraulically, along with the given liquid.

Factors to be Considered in Slurry Pumping

• Particle size- d85= 3mm- means 85% of particles have a diameter of 3 mm or less.

• Specific gravity of solids particles (SGs)

• Specific gravity of liquid (normally water which is 1)

• Concentration of solids by volume (Cv)

• Concentration of solids by weight (Cm) (where Cv, Cm is given in % it means it is for slurry)

• Specific gravity of slurry (SGsl)

• Mass fraction (% of particles below 75 μm)

• Shape of particles (Round or Flat)

Characteristics of Slurry

1. Non – Settling Slurry - In this particle size is less than 60-100 μm. A non settling slurry can be defined as a Homogenous Mixture. It is comparatively easy to pump non-settling slurry.

2. Settling Slurry- In this particle size is greater than 100μm. Settling slurry can be defined as Pseudo-Homogenous Mixture OR Heterogeneous Mixture. This is where the demand on slurry pumps increase.

Few Slurry Pump Applications

• Steel Plant- Pumps for mill scale transportation.

• Thermal Power Plants- Pumps for fly Ash slurry handling.

• Hydel Plants & projects- Pump for removing silt and sediment from tailing dams, trenches, channels, Dam gallery, coolant sumps, etc…

• Mineral Processing Units.

• Mines & Quarries

• Various industrial uses like E.T.P, Cement plants, Fertilizer & Pharmaceutical Plants.

• Sand dredging, washing and cleaning.

• Lagoon cleaning & dredging near dockyard and ports.
