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.

Planning for New Digester Pumps
Climate changes in the Northeast has also played a role in nudging local government to invest in sewage treatment pumping equipment as unpredictable storms can overload the system.
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 to Pump Wet Wipes and Cooking Oil
In North America, municipal wastewater treatment operators routinely voice their concerns to Wastecorp about the use of wet pipes by the general public and then flushing them down the toilet. “Do you guys make a pump that can better handle the wet wipes” is a question Wastecorp frequently receives at our sludge pump call centers. Jim K. from Winston Salem North Carolina tells it like it is:

What You Didn’t Know About Double Disc Pumps
Can a Double Disc Pump Have Ball Valves?
Yes. In fact, ball valve technology is helping to usher in the next era of double disc style pumps. The ball valves help to break up solids and make pumping thicker municipal sewage easier. The ball valves also make it much easier to maintain the pump.
Dirty Secrets in The Double Disc Pump Business
several markets and we receive and document regular reports from our local double disc pump distributors as to who is saying what to consulting engineers and operators and then modifying our strategy to encourage competition in the double disc pump marketplace.
Diaphragm Pump for Sewage Pumping
A WWTP just expanded and upgraded their pump facilities. The facility chose double diaphragm pumps to transfer sewage from digesters for secondary treatment. Project participants included Mud Sucker Diaphragm Pumps and pump manufacturer Wastecorp Pumps.
How to Change The Disc Assembly on A Double Disc Pump
The video below shows how to change the trunnion on a Sludge Pro double disc pump. As you can see most of the maintenance is done with the operator standing up and most components visible to the operator.
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.
