centrifugal pump for slurry factory

Firstly, analysing your duty helps us to determine whether you are using the type and size of pump best suited to your needs. Cavitation can occur due to surges; a very effective way to solve this problem is to install a choke on the pump head to increase the pressure on the casing, which then absorbs the surge, or to add a choke to the output to reduce the surge.

Some quench seals are planned to replace the tight fitting outlet restriction with a secondary seal and a top outlet that can be piped to capture the used quench fluid and drain it from the rotating assembly. However the principle is the same, we try to cool the seal rather than flush it in any way.

With the development of the dredging market, the requirements for dredging equipment are getting higher and higher, and the suction resistance and vacuum of dredging pumps are getting higher and higher, which has a great impact on the efficiency of dredging pumps and the chance of cavitation is getting higher and higher. The number of >dredging pumps is also increasing.

Corrosiveness of the slurry

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.

-When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.
