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.

Selecting a dredge pump

There are three different >types of slurry pump impellers; open, closed, and semi-open. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency.

Consider the impeller. Slurry pumps must have thicker vanes than water pumps to prevent wear. Due to the increased thickness, there will be fewer vanes, otherwise the passages will be too narrow and will affect the performance of the pump. The impeller should have a large enough passage so that the largest solid particles can pass through without clogging.

All products are mainly supplied to environmental protection, wastewater treatment, urban water supply and drainage, mine, metallurgy, coal, petrochemical, building material, thermal power FGD, river dredging, tailing disposal and other fields.

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.
