The staff request for the City Council is to review and consider for approval the purchase of the Penn Valley 6" Model 6DDSX107CNU-MK1 Double Disc Pump unit from Mader Electric Motors in the amount not to exceed $49,982.00 utilizing the “Piggyback process” from Lee County Florida contract No. B190409JJB in accordance with the City’s purchasing guidelines.

The Water Reclamation Facility generates about 140,000 to 300,000 gallons per-day (GPD), of sludge that needs to be dewatered for Sludge Hauling as part of the Biosolids process. The Penn Valley pump gives the plant operations a greater capacity gallons per-minute (GPM), that allows pumping directly to the Sludge Press when needed for cleaning the Thickener tank. The Penn Valley Pump has a turn-down of 20 to 1 meaning it can pump as little as 16 GPM while capable of preventing backflow. Positive displacement pumps can't provide this ability. Replacement parts for Penn Valley are 1/3 the price of Positive displacement pump parts. The Penn Valley pump will replace a pump at the end of its life.  Where possible, the parts of the existing pump will be repurposed as backup parts for the plants existing pumps.
