How does a dredge pump work?

A slurry is any mixture of a fluid (such as water) and a powdery solid. Slurries are used as a convenient way to handle bulk solids in the mining, steel processing, foundry, power generation and, more recently, frac sand mining industries. Slurries typically behave like viscous viscous fluids, flowing under gravity, but can also be pumped as needed.

Caution: A common mistake is to over-pressurise the box and damage the expensive mechanical seal.

As new coal-fired power plants come on line to meet the growing demand for electricity in the US and around the world, there is an increasing need to clean plant emissions to meet clean air regulations. Special pumps help to operate these scrubbers efficiently and handle the abrasive slurries used in the flue gas desulphurisation (FGD) process.

Flushing is defined as a fluid which is introduced into the seal cavity on the process fluid side, close to the seal face, and is normally used to cool and lubricate the seal face.

The winch dredger is usually equipped with a hull-mounted dredge pump, which has an impeller centered at or below the draft line for further production and improved suction efficiency.
