Next Generation Double Disc Pumps
Pump from 0-250 GPM
Overall Rating 4/5
The Sludge Pro 4DDWP double disc pump was installed for a 30 day trial as a replacement for our existing lobe pumps in Lakewood Township, NJ. With no piping changes this pump installation went ceaselessly. We are pumping animal fats 24/7 and the pumps have worked well for us so far. We considered a few other double disc pump makes. We tried theirs already and do not like their belt driven configuration and have not made a final decision until we try all of them.
Select from Santoprene, Buna-N, Viton, Teflon, Nordel or standard Neoprene
