Pumping Power

West Deptford, N.J., nuclear facility addresses pumping requirements with ANSI installation

The West Deptford Energy Station in West Deptford, N.J., is a brand new 715-mw nuclear power plant with CH2M Hill as the contractor. It required eight Goulds 3196 ANSI pumps, or an approved equal. Pentair worked closely with its distributor and was able to get its 3550 Series ANSI pumps accepted by the facility. Pentair then prepared a competitive pump package for its distributor, which submitted its bid to CH2M Hill and was awarded the job. Pentair received a purchase order a short time later and started assembling submittal data.

Included in the order were the following pumps:
• Two demineralized water pumps—size 2x3‐6 316 SS pumps with single-cartridge seals. The pumps were coupled to 7.5-hp, 3,600-rpm, premium efficient TEFC motors and mounted on bent formed carbon steel bases with Pentair’s enclosed coupling guards.
• Two reverse osmosis permeate pumps—size 1.5x3‐8 SS pumps with single-cartridge seals. The pumps were coupled to 10-hp, 3,600-rpm, premium efficient TEFC motors and mounted on bent formed carbon steel bases with Pentiar’s enclosed coupling guards.
• Two raw water pumps—size 3x4‐8G SS pumps with single-cartridge seals. The pumps were coupled to 25-hp, 3,600-rpm, premium efficient TEFC motors and mounted on bent formed carbon steel bases with Pentair’s enclosed coupling guards.
• Two wastewater pumps—size 8x10‐15G SS pumps with single-cartridge seals. The pumps were coupled to 50-hp, 1,150-rpm, premium efficient TEFC motors and mounted on bent formed carbon steel bases with Pentiar’s enclosed coupling guards.

All the pumps required Certified Material certifications on the cases, impellers and shafts, as well as certified hydro, performance and NPSH tests.

The ANSI style pumps were assembled and tested in Pentair’s Kansas City facility and met or exceeded performance requirements. Once the engineer approved them, they were shipped to the job site. Since that time, they have been installed at the plant, and the initial startup has been completed with the pumps performing as expected. The new 715-mw nuclear power plant, featuring Pentair’s 3550 Series ANSI pumps, is expected to go online in the spring of 2014.
