Three approaches can be taken when it comes to the basic pump design for fluids containing such abrasive particles.
- To use a hard, wear-resistant material for the internal components such as PE or chrome.
- Reduce the velocity of the fluid in the pump chamber by using a low shear and slow pumping action .
- Use a soft material with tear resistant properties as found in hose pumps, AOD pumps and eccentric disc pumps.
