Some models can generate discharge pressures up to 260 ft. (80 m).

The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.

The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.

Choosing The Right Slurry Pump For Your Application

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.

Pumping slurry can cause excessive wear and tear on the pump and its components as the mud can clog the suction and discharge lines.
