With tough sludge pumping applications like those found at municipal Wastewater Treatment Facilities, (WWTP’s) having the right primary sludge pumps can help reduce hassles and your spare parts budget down the road.

Double Disc Pumps and Municipal Sewage Pumping
For years, we have been asking wastewater treatment plants (WWTP) what they like about double disc pumps and what they don’t like. We have even been compiling a database with what regions of the USA and Canada have success with this type of pump for sewage and which areas have had more challenges.
One of the things that most WWTP’s say is that there has been limited competition in the specifications put out for bid by municipalities and consulting engineers working on wastewater projects. As we all know a monopoly in the pump industry is seldom a good thing for quality, innovation and of course pricing for pumps and parts.
How a Double Disc Pump Works
We have all seen the outside of a double disc pump but rarely do we see what makes the pump actually work. Just to review, a double disc pump is a positive displacement pump that uses a trunnion (elastomer), a disc and a connecting rod to force sewage from the suction side to the discharge side of the pump by creating a vacuum inside the pump body. The valve chambers with the black check valves you see in the photo help to manage higher than normal concentrations of grit and solids in municipal wastewater.
Resolving Sewage Pump Problems at Smaller WWTP’s
How to resolve sewage pumping problems at smaller WWTP’s is a question on the minds of thousands of operators worldwide. These facilities pump municipal sewage, storm water, melting snow, road grit and so much more for smaller communities. While the gallons per day pumped may not be as high as urban sewage treatment plants, the need for reliable sludge pumps is just as great. Wastecorp was contacted by a South New Jersey WWTP to provide upgraded sewage pumps to transfer wastewater, sludge and storm water from a smaller holding tank area. The pumps then transfer waste to both the facility’s lift station and digesters. The sewage pumps were also specified to unload local tanker trucks delivering everything from septic waste to waste trap grease and other solids laden liquids.
