Choosing Dry Slurry Pumps Versus Submersible Slurry Pumps

A clear clean fluid supplied from an external source is normally used which is delivered to the main sealing surface on the fluid side of the sealing process. By using a closed gap throat bushing, the stuffing box can be back-pressurised to a higher pressure, ensuring that the flushing fluid does not flash across the seal face.

From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.

The first major requirement for >slurry pumps is to provide adequate service life. The erosive and corrosive effects of slurries, such as the impact of high velocity flow of liquid/solid mixtures, can be really challenging. In many applications, some of the solids in the mixture are larger than the particles normally specified; therefore, the pump should be able to pass through them without causing any damage or operational problems.

Submersible pumps offer many advantages over dry installation or even semi-submersible sump pumps. Submersible pumps are more flexible and efficient than alternatives.
