Tri-Clover PR/PRE/PRED Series Pumps

Tri-Clover's PR Series rotary lobe pumps were designed for the dairy industry. The original PR series featured rubber rotors only, while later PRE (single flush) and PRED (double flush) models included a stainless steel rotor option. Tri-Clover (now Alfa Laval) no longer manufactures the PR, PRE, or PRED pumps, but seal kits, rotors, shafts, and some front covers are still available. Central States Industrial (CSI) still supports the PR series by supplying these genuine OEM spare parts for repair or maintenance.
