Next Generation Double Disc Pumps
Pump from 0-250 GPM
Overall Rating 4/5
Our facility had been hesitant to experiment with double disc pumps. For one, we were concerned about the grit rupturing the trunnion. We found the Sludge Pro to be a tough pump for these applications and did no maintenance at all on it during our six month trial. We are strongly considering using these pumps in our other facilities.
