Since we launched the Sludge Pro Disc Pump product line, there have been several questions as to whether or not a single disc or double disc pump is more appropriate for specific wastewater treatment applications.

To be clear, there is not always a need for a double disc pump. A single disc pump will fit the pump specification properly. One of the reasons why consulting engineers and contractors have put the double disc pump specification in place is because up until recently there have been few other alternatives. In many cases, a double disc pump is simply overkill in both pump, footprint, cost and maintenance time down the road.

Take the Sludge Pro single disc pump for example. This pump series offers up to 150 GPM pumping capabilities with a single disc, trunnion and pump body.  This reduces the footprint in most municipal WWTP’s by at least 20%. You also reduce repair costs by replacing only one disc, trunnion and connecting rod instead of two. With over 21 years of pump manufacturing experience, Wastecorp designed the Sludge Pro with a heavy duty ball valve configuration because this design has demonstrated improved solids and slurry pumping capabilities over traditional double disc pump manufacturers. The Sludge Pro single disc pump is available in 3”, 4” and 6” connection sizes with discharge head up to 184’ or 80 psi.
