Since the Barnes 4SHV pumps were installed in August 2012, they have been working flawlessly in the Cedar Cove lift station. |
Due to the consistent clogging that the original submersible pumps were experiencing, APRS suggested using two Barnes 4SHV vortex solids handling pumps built by Crane Pumps & Systems at its plant in Piqua, Ohio. This replacement included pumps specifically engineered to prevent against clogging occurrences and increase seal life - the perfect replacement for two pumps that were frequently failing.
The vortex impeller inside the Barnes pump is backed by extensive clog testing. It is uniquely designed to create a powerful circulation and whip the solids through the system. Further, Barnes SHV pumps are specifically designed for longer seal life. The mechanical seal is made of grit- resistant silicon carbide, and the heavy-duty, large- diameter shaft plays a key role in reducing the shaft deflection that reduces mechanical seal life.
The pumps also have the Plug-N-Play power plug that allows for easy pump removal without having to disconnect the cable at the control panel and pull it from the conduit. Given that it was costly and labor-intensive to send an electrician out to pull the pump, this feature provides significant advantages for the town of Fishers. Maintenance staff can quickly and efficiently remove the pump if needed without risking potential pinching and damaging of the cord.
Before the station was renovated, the old pumps were running 832 hours per year. Since the restoration, the Barnes pumps are currently running almost half the amount of time. Although these higher-horsepower pumps do consume 7 kwh/day more electricity ($1.20/day), the municipality has ultimately seen a significant overall cost savings with the reduction in service calls and maintenance costs. Likewise, the third pump that was often brought into service during repair is no longer needed and does not need to be maintained.
Since the Barnes 4SHV pumps were installed in August 2012, they have been working flawlessly in the Cedar Cove lift station. "We are very pleased with the performance of the SH pumps," said Farnham. "There have been no clogs or corrective maintenance during the first 18 months of operation."
Pleased with the success of the installation, the town of Fishers has initiated a proactive submersible pump replacement program with the CP&S product line throughout the municipality.
