seal for 5 inch dredge pump manufacturer

As this limestone slurry needs to be moved efficiently through a complex industrial process, the selection of the right pumps and valves (taking into account their whole life cycle costs and maintenance) is crucial.

Light-duty Slurry Pump

Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.

We use CFD, CAD method for product design and process design based absorbing experience of world leading pump companies. We integrate molding, smelting, casting, heat treatment, machining and chemical analysis, and have professional engineering and technical personnel.

Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.

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.
