For Kaolin slurry filter presing we are using progressive cavity pumps.After three months of operation we found that the pumping rate is reduced a lot.Upon investigation we found taht this is because of the abrasion. 150 micron Chromium coating done, still after three months ,this again failed.
The rotor is having 125mm diameter and is of 2.8m long. As the medium handled is Clay Slurry with low pH the MOC of the rotor is SS316. This rotor rotates inside a neoprene rubber stator while pumping the slurry. For the pump to develop a pressure of 10 bar the sealing between th rotor and stator is very important and the damage to the sealing area reduces the pump through put.
We are looking for a suitable method for increasing the abrasion resistance of the rotor along the sealing area.
Any suggestions?
