Variable speed wet rotor circulators
Grundfos Pumps produces a permanent magnet, variable speed wet rotor circulator, reduces power consumption.
The MAGNA, from Grundfos, with its permanent magnet motor design allegedly reduces power consumption by 50% or more. The unique patented AUTOADAPT feature controls pump performance automatically within defined performance range, reportedly ensuring lowest possible energy consumption without sacrificing comfort. It’s purportedly easy to install and simple to operate for replacement applications.
Standard Features include:
- Permanent magnet motor design that will avoid motor slippage problems common to induction-type motors, while delivering a starting torque four times higher than a standard induction motor.
- AUTOAdapt function automatically modulates circulator performance to match ever-changing system demand, cutting power consumption by a minimum of 50%, as compared with other circulators in its class.
- Plug-and-play convenience: Ten-foot-long line cord connects the circulator to a wall outlet, with no wiring required, eliminating the need to open a terminal box to make electrical connections
- Integrated frequency converter allows built-in intelligence analyzes current conditions and adjusts performance accordingly to ensure maximum efficiency during operation
- Low Noise Level: When in operation the noise level of the MAGNA is less than 35 db, equivalent to a whispered voice.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
