Of the several horizontal split case pumps Gwinnett County reviewed for retrofitting of its 22-year-old Filter Treatment Facility, Patterson Pump Company’s specifications more closely matched the facility’s precise needs. The Gwinnett County Public Utility selected four 36 x 30 MAA pumps (33,415 gpm and 129 ft tdh), and three 20 x 18 MABS pumps (10,070 gpm and 159 ft tdh) for the retrofitting.

“There were no complications at all during installation, and their variable speed has managed pressure exactly as we want it, during peak times and slow, middle-of-the-night periods. Our economy of operation was increased over the fixed speed pumps we used previously,” says Maintenance Superintendent Reza Baniassad.

Switching to low rpm, variable speed, horizontal split case pumps increased head and capacity, and ensured more efficient operation, mechanical dependability, low-cost maintenance and growth potential.

Neal Spivey, Director of Water Production, says he is especially pleased with the current 150 mgd capacity of the facility.

“It allows us to serve our 153,000 plus customers more efficiently and gives Lanier assurance that we will meet our growth requirements well into the future,” says Spivey.

When you need a pump you can depend on, with little to no maintenance, get a Patterson pump.
