Nidec Motor Provides Constant, Variable Speed Pumping Solutions Nidec Motor Corp. offers water in- dustry customers two certified NEMA Premium efficient vertical hollow shaft product lines: new Sinewave Optimized motors for constant speed pumping, and inverter duty products for variable speed pumping. Not all pump- ing applications require a variable speed motor to maintain constant water pressure or flow. For these circumstances, Nidec offers new U.S. Motors brand Sinewave Opti- mized premium efficiency vertical high thrust motors. These motors, from 7½ hp to 600 hp, meet the new Department of Energy efficiency requirements and provide a lower cost alternative to inverter duty motors. www.nidec-motor.com Unitra's Die-Cast Aluminum Pumps Provide True Performance Unitra was the first company to ever develop the die-cast aluminum contractor pump.

The system is available with either three or seven chan- nels, with monitoring ports easily constructed at different depths in each channel. The 3-channel CMT is 1.1 inches in diameter and ideal for direct push installations. The 7-channel sys- tem is 1.7 inches in diameter. Both CMT systems are easy to in- stall, design flexibility allows port lo- cations, and monitoring strategy to be finalized right on site. Depth-discrete groundwater data provides assessors with a better understanding of the three-dimensional flow and distribu- tion of contaminants in the subsurface. www.solinst.com Twitter @WaterWellJournl WWJ January 2017 49 Siemens Adds Class 82 Slim Line NEMA Pump Panel Siemens announces the newest ad- dition to its extensive line of pump panels, the Class 82 Slim Line NEMA pump panel. The new pump panel is designed specifically for the agricul- tural market as it is well suited for irri- gation or similar pumping applications and is built to withstand the harsh elements of the outdoors. The new pump panel has a compact lightweight design that makes this an attractive alternative to the standard Class 87 pump panel. The smaller design also eases installa- tion. The pump panel is almost half the size and weight of the Class 87 panels. www.usa.siemens.com/controls
