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.
