BARNES® SITHE – A cost saving solution to your clogging problems


Hamilton, AL
The city sewer district consists of 19 lift stations that cater a population of 6500. It’s treatment plant has a capacity of 1.5 million gallons per day.


The station has high solids content and the City had to pull out pumps monthly to unclog. Typically rags, hair, mop heads and debris were clogging the pumps.

Crane Pumps and Systems’ developed and provided a 7.5 HP Barnes® Sithe chopper pump with a mono-vane im-peller. The pump has been chopping all solids and hasn’t clogged once in over 8 months of operation.

Lift station at the waste water treatment plant in Hamilton, AL has an unique application. Sewage from across the city is pumped on to incline screens in the treatment plant. Water from the screenings along with rain- water and debris is collected in a sump. This water is again pumped back to the screens in a closed loop.

The station evidently has high solid content. City had to de-rag the non-clog pumps every month. These pumps were unable to handle solids like mop heads, rags, greasy hairballs, plastics and debris.

Solids in the lift station

Ron Hylton, treatment plant’s supervisor, approached Pump & Process Equipment (PPE) for a permanent and cost effective solution for his clogging problems. PPE and Crane Pumps and Systems worked together and provided a Barnes® Sithe 4SCMD 7.5 HP chopper pump in June 2017.

It’s been 8 months since Sithe’s installation and it hasn’t clogged even once. The first time it was pulled was for a 6-month regular checkup. Sithe’s stainless steel heat treated blades were found in pristine condition and had retained sharpness. It continues to operate as the lead pump in the station obliterating even the biggest and toughest of solids.

“I was impressed by the looks and design of the pump. At present, Sithe is doing a great job running by itself.”Ronald Hylton, Wastewater Plant Maintenance Supervisor
