Types of Slurry Pumps Slurry is a mixture of solids and liquid, generally water. The particles can be both abrasive & nonabrasive, 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.
There are many factors to be considered while selecting slurry pumps like; Particle size- Specific gravity of solids, Specific gravity of liquid, Concentration of slurry, Shape of particles etc. Slurry can be further classified in to two types – 1. Non – Settling Slurry: In this type of slurry, the solids do not settle to the bottom, but remain in suspension for a long time. A non-settling slurry acts in a homogeneous, viscous manner, but the characteristics are non-Newtonian. A non-settling slurry can be defined as a homogeneous mixture. 2. Settling Slurry: Settling is the process by which particulates settle to the bottom of a liquid and form a sediment. Particles that experience a force, either due to gravity or due to centrifugal motion will tend to move in a uniform manner in the direction exerted by that force. For gravity settling, this means that the particles will tend to fall to the bottom of the vessel, forming a slurry at the vessel base.
