My question is regarding the pumping of dregs from a green liquor clarifier. We currently use ODS pumps (plunger type diaphragm pump from Dorr-Oliver, now GL&V). We constantly have leaks, diaphragm failures, and solenoid failures with these pumps. Does anyone have a suggestion for a better type of dregs pump (discflo, pitbull, other?)? Or, does anyone have any best practices as far as preventative maintenance for ODS pumps? Thanks in advance!
