Pump Industry News: Replacing a Komline Sanderson Plunger Pump

Komline Sanderson Plunger Pump

Komline Sanderson Plunger Pump

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

Resolving Sewage Pump Problems at Smaller WWTP’s

Solving Sewage Pump problems

Solving Sewage Pump problems

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

Double Disc Pumps and Municipal Sewage Pumping

Double Disc Pump

Double Disc Pump

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 at a WWTP

Primary Sludge Pumps

Primary Sludge Pump Options

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

Double Disc Pump Comparison: The State of the Double Disc Pump Business

Compare Penn Valley and Sludge Pro Double Disc Pumps

Double Disc Pump

Wastecorp was recently at WEFTEC exhibiting our newest double disc pumps for the municipal wastewater treatment market and industrial fluid handling space. Wastecorp’s Sludge Pro double disc pump marketing program continues to focus on building awareness with WWTP operators and consulting engineers that competition exists in the double disc pump space and the market offers a more robust alternative than traditionally known.

We have noticed that when a double disc pump for a WWTP upgrade or expansion goes to the planning stage and/or bid stage, we get calls from consulting engineers saying that the competition or their pump distributor make misleading or incomplete statements about double disc pump competition. What it boils down to is trying to eliminate competition. In America, we call this an attempt to create a monopoly. History has shown that monopolies are seldom good for competition in the pump business or any other business for that matter. History has also shown that monopolies in the United States aren’t looked at favorably by either regulators or the public. Continue reading
