A large coal fire power plant in the Southeastern US turned to Vulcan Pumps for solutions for their grit sump system. The application uses 2 HDS 75M pumps in smaller sumps with weir walls that spill over into a larger basin with 4 HDS 200L pumps. These pumps see all the used plant water and is a collection area from washdown sumps located throughout the plant. The HDS pumps were chosen for their abrasion resistant hard metal construction and internal slurry seal design to handle the grit, ash particles, and coal fines that may end up in the sump.
