china hot sale submersible slurry 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.

1. The two types of pumps are all centrifugal pumps in the working principle. They are machines that increase the energy of solid and liquid mixtures by means of centrifugal force (the rotation of the impeller of the pump). A device that converts electrical energy into kinetic and potential energy of a medium.

Step 4

Positive displacement slurry pumps with limited capacity to deliver high head are used to pump slurry through pipes with very high solids concentrations.

Using rubber as a wear lining material means

From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.
