When Wastecorp designed the Sludge Pro Double Disc Pump we set out with the goal to engineer the easiest to service sewage pump available to engineers and WWTP end users. One common request from the engineering community was that an operator or maintenance person would never have to crawl under a double disc pump with a casting hanging overhead and the potential for sewage to leak over the operator. When you think about – why would anyone design a pump like that? Our answer is that you would have to ask the competitor because Wastecorp would not.
Servicing a double disc pump
The video below shows how to change the trunnion on a Sludge Pro double disc pump. As you can see most of the maintenance is done with the operator standing up and most components visible to the operator. Continue reading
Orange County Sewage Pumps
Orange county is home to dozens of resorts, hotels and theme parks which generate tens of millions of gallons of wastewater that needs to be treated every year. When an Orlando, Florida renewable energy company earned a multiyear contract to accept waste from local resorts and theme parks, they needed severe duty pumps to transfer thick slurries and solids.
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.

What is a Penn Valley Pump (PVP)?
The Penn Valley pump is a diaphragm pump. PVP has fully acknowledged this in their patent # US 7,559,753 B2. The patent references George Burrage’s (a family member of PVP President) patent application # GB 2013287A as the basis of construction for the PVP pump. Nowhere in GB 2013287A does it reference a disc at all. This legal document fully acknowledges the fact that the Penn Valley pump is a diaphragm pump. PVP also Continue reading

Primary Sludge Pumps
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.
