Steamtip of the month: Steam-powered condensate vs. electric pumps
What are the advantages of steam-powered condensate pumps over the electric pump?
Steam-powered condensate pumps offer numerous advantages with the following key benefits:
1. There is no requirement for electric motors, level switches and electrical panel – thus simplifying installation.
2. Mounted on a skid, a steam-powered pump package has very few connections to make; hence it is almost like “plug-and-play.”
3. Cavitation problems are associated with electric pumps which can impact negatively on start-up as well as operating cost down-time. Whereas steam-powered pump does not suffer cavitation as it is a positive displacement pump.
4. Steam-powered pumps have no mechanical seals or packing glands to leak – ensuring virtually trouble-free operation.
5. A flow counter can be easily incorporated to provide an economical way of metering the amount of condensate returned.
6. Steam-powered pumps are compact in size resulting in space-saving.
7. As electrical power is not required to operate the pump, steam-powered condensate units are ideal for hazardous areas.

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.
