The details of the project called on the requirement of pumps to transfer ground up seafood shells, grease trap waste, utensils, animal renderings, wastewater and more. In this application, the waste is unloaded from a tanker into a waste pit. The waste is then transferred to a conveyor system which then separates most of the foreign objects like utensils, large solids, plastic bags and more. The remaining waste is sent through the Sludge Master plunger pump and then to the digesters of the wastewater treatment plant. With millions of people visiting Orlando resorts and theme parks every year, this amounts to a lot of waste, as tanker trucks deliver new loads of slurry like liquid waste around the clock.

Many of our wastewater treatment plant operators looking to upgrade their sewage pumps to the next generation plunger pumps have a wide set of options for a no piping change or little alternation to the existing set up. New sewage pumps can help make the facility more efficient and productive. This is available to all plunger pump customers including competing makes like Komline Sanderson* and Carter* Plunger Pump customers.
With a 3 hp motor, and 4″ discharge. Mike D. from Fort Worth Texas illustrates a number of pump questions we get from public utilities operators.
“I am looking to replace 2 Komline Sanderson KS-9 plunger pumps at my wastewater treatment facility. The pump characteristics are 140 GPM at 90 ft head. We get some grit in our sewage and we have a grinder on the suction lines of both pumps. Current pump is duplex plunger pump general arrangement. What is your equivalent of this pump? Do I have to make piping changes to my effluent lines? And what other pumps do you manufacture that we could consider installing? .” Thanks, Mike D. Fort Worth, Texas
Well Mike, you have Continue reading
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. Continue reading
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. There have also been some stop and starts with competing technology from underfinanced companies trying to knock off the design with “dia-disk” pumps, etc.
The other major suggestion from operators is that double disc pumps have to be able to handle grit and solids more effectively. Otherwise they say, they would rather go with a plunger pump, rotary lobe pump or a progressive cavity pump. Continue reading
Primary sludge pumps are typically used in municipal Wastewater treatment facilities to transfer digested sewage and sludge. This is a broad pump category that encompasses positive displacement pumps to pump sludge in ranges usually up to about 500 GPM. The choices of pumps vary from double diaphragm pumps, plunger pumps, double disc pumps, rotary lobe pumps, progressive cavity pumps and more.
In todays pump marketplace, there are generally two schools that operators and consulting engineers follow when specifying primary sludge pumps. The first option is Continue reading
