china pump for wastewater manufacturer

Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.

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

A typical pump solution for this application is to install a hard metal >slurry pump to withstand these types of conditions. Hard metal pumps need to be able to withstand the most severe abrasive slurry service and they also need to be designed to be extremely easy to maintain and safe.

Selecting a dredge pump

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.
