•Case Study: Pumping Up Safety, Efficiency And A Smarter Design
By The Gorman-Rupp Company
The Progress Energy's Lee Plant, located in Goldsboro, N.C., originally enlisted nine vertical sump pumps within the plant as yard drain pumps – pumps that have motors that are located above the pump and a line shaft that extends down into the length of the sump – whereas the pump is actually at the bottom of the sump. The pumps were enlisted to remove excess water that accumulates from rainfall and storm drains, equipment wash down and general water overflow — all of which are pumped to a retention settlement basin.
With traditional vertical-line sump pump designs, the pumps remain housed in tight, confined spaces. Therefore, when a team member needed to enter the area for maintenance, a series of confined space entry procedures had to be followed to secure personnel safety. Otherwise, an overhead crane was required to remove the pump from the area, which was a lengthy process – often an all-day procedure.
By virtue of the pump design, each pump has what is referred to as a V-belt drive. In as much, the company is able to simply change the drive and change the speed of the pump, which in turn will change the capacity of the pump or its capability – another feature that was not previously offered with the existing vertical line sump pump. "If the plant was expanding, if the sumps were required to service a larger area, if there were some kind of an environmental work with their waste treatment, or for regulatory reasons they needed to pump to a different site, all of these scenarios could increase the amount of the discharge pressure or discharge head that particular lift station or sump station would need.
