They operate continuously without adversely affecting pump performance, and meet demanding pumping challenges, including abrasive and corrosive fluids and materials that are shear sensitive and viscous. Its no-seal design eliminates leakage and contamination. The liquid is in the hose, which is the main part that needs to be maintained.
