Things are heating up in the marketplace for double disc pumps and competition has a great way of exposing the true colors of competitors. Hearing what one double disc pump competitor says about another reinforces the need to do your homework so you are getting an accurate picture of the benefits and drawbacks of each make.

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. This was just the case for the City of Meridian’s recent wastewater treatment facility upgrade and expansion in Meridian, Idaho.
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?
You can find them on wastecorp.com or click on this link and we will take you to the double disc pump selection page. You can also call Sludge Pro Double Disc Pumps at 1-888-829-2783 or email email@example.com
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
Any wastewater treatment plant operator will typically tell you that one of the biggest hassles they face daily is pumping stringy material from a variety of sources. The problem here is that the material tends to get stuck in the impellers of trash pumps and wreak havoc on lobe pumps. Phil from Clyde, Texas tells us about his quest to find a better solution:
“A buddy of mine has been using your Mud Sucker diaphragm pumps at a public works facility down the road from me and we are considering the same. Our WWTP pumps a lot of stringy material from mops and unknown fibrous material. We are using non clog trash pumps now but make no mistake, the impeller still gets clogged. We need something better. We have seen diaphragms used on honey wagons to pump all sorts of material and they have worked. We work with less than 5% solids and need to pump around 100 GPM with a TDH of about 15’. What do you recommend and what do I need to budget?” – Phil H. Clyde, Texas
