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

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

What You Didn’t Know About Double Disc Pumps

Wastecorp recently exhibited at a national water quality conference where we had a chance to discuss our exciting double disc pump technology with engineers, end users and pump distributors. We addressed some of the most common issues/questions below:

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. With the traditional clack valve style double disc pump, debris can get stuck in the clack and trunnions which may reduce pumping productivity. With a Sludge Pro® Double Disc Pump you simply open up the valve chambers, check for any debris and blockages and get back to business.  Just because one type of double disc pump has a clack valve doesn’t mean others have to.

Is The Term Double Disc Pump a Registered Trademark?

No. In fact, it is unlawful for any one manufacturer to place a registered trademark “®” designation next to the generic term “double disc pump”. It hurts competition and misleads consumers.

Do You Have to Crawl Under a Sludge Pro® Double Disc Pump to Conduct Maintenance Like You Do Other Makes?

Absolutely not. Wastecorp would never design a pump where an operator or maintenance person had to crawl underneath a pump with hundreds of lbs potentially hanging overhead. This poses a safety risk and may lead to serious injury or death.

Is there really a difference between the clack valve style double disc pump and Wastecorp’s Sludge Pro Double Disc Pumps?

Yes. First, the Sludge Pro® includes a hydraulic jacking system that raises the shaft so the trunnion and wet section can be worked on while the maintenance person is standing up. Who would want to crawl underneath a pump to conduct maintenance?  Second, municipal sewage involves a lot of grit and solids to be pumped. Wastecorp designed a disc pump better able to manage solids and thicker sewage.  Third, you won’t find swan necks or clack valves on a Sludge Pro® A pump that involves removing the swan neck to access the pump internals may cause reduced productivity at a WWTP.  Belt and pulleys are another time waster that you won’t find on a Sludge Pro® double disc pump. Energy efficient direct drive systems reduce the motor hp required so the sewage pumping operation can operate more efficiently.

What is the difference between a single housing design and a three housing design?

A three housing design doesn’t really mean anything. It is the preference of the pump manufacturer. However a three piece pump body design may lead to increased parts to replace and repair and possibly more down time for the facility. A single housing design may improve access to the pumps internals and reduce the amount of pump maintenance people needed to work on the pump.

What drive systems are available for double disc pumps?

Electric driven and engine driven (usually) diesel are preferred by most facilities.

Where can I find Engineering Specifications on Double Disc Pumps?

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
