china anti abrasive sand slurry pump

The most important thing here is to determine the pump power required to deliver a specific fluid flow at the desired or required differential pressure. Consider the following.

Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.

The FGD process begins when the limestone feed (rock) is reduced in size by crushing it in a ball mill and then mixed with water in a slurry supply tank. The slurry (approx. 90% water) is then pumped into the absorption tank. As the consistency of the limestone slurry tends to change, suction conditions can occur which can lead to cavitation and pump failure.

Slurries are divided into two main categories: non-settling or settling. Non-settling slurries consist of very fine particles, giving the illusion of increased apparent viscosity. These slurries usually have low wear characteristics, but require very careful consideration when selecting the right pump, as they behave differently from ordinary liquids.

Slurry Pump

Depending on the abrasive nature of the slurry, it is important to select the ideal seal. Slurry pump seals should have a hardened surface made of silicon carbide or tungsten carbide. Vortex pumps use patented seal technology that utilizes a double mechanical seal setup and a separate seal flushing system. This allows the sealing surface to be kept cool at all times without causing the slurry to overheat the seal and crack the surface.
