There’s no substitute for hands-on experience when trying to learn the intricacies of a pump’s critical role in a hydronic heating system. So when the University of Nebraska at Lincoln needed a large centrifugal pump to use in its Construction Management classes, ITT Corporation’s Bell & Gossett unit was there to help with a donation of a B&G Series VSC, double-suction, vertical split-case pump.
“We always try to find a good balance between ‘book learning‘ and hands-on applications using real-life installations,” said Tim Wentz, the department’s Associate Professor. Adding that, “We were in need of a large centrifugal pump to demonstrate the functionality of such a piece of equipment.”
Wentz, who approaches teaching with a hands-on method, plans to utilize the cut-away VSC Pump in teaching his students about the functionality and role of pumps for various applications. “It’s one thing to read in a book about how pumps work, but it’s another thing to actually install one and experience how it operates. The Bell & Gossett VSC demo unit has a cutaway volute to show its inner components such as the impeller and shaft.”
Wentz will use the VSC for a variety of purposes including:
- Teaching students to plot out its performance on a pump curve and observe how efficiently it is running.
- Understanding the advantages of VSC Pumps for space savings in tight installations
- Explaining, “how and why a centrifugal pump works.”
- Actually showing the inner workings of a pump
University personnel along with student volunteers set the pump in place in the University of Nebraska at Lincoln’s HVAC lab. The lab also has a variety of equipment that students can use for hands-on training, including a Bell & Gossett 1510 base mounted pump, a shell and tube heat exchanger, plus a variety of Bell & Gossett pumps and McDonnell & Miller boiler controls. In addition, Professor Wentz’s students also use Bell & Gossett’s on-line pump selection program to understand proper pump selection.
Verne Simmonds Company, B&G Representative in Nebraska, has been working with Wentz and the University for some time and has provided several pieces of equipment to the school over the years. Recently, when Dan Holtmeyer, Principal at Verne Simmonds heard that UNL was looking for a large split case pump, he immediately contacted B&G.
“The school has an excellent reputation for not only providing an outstanding HVAC education, but they also give back to the community,” Holtmeyer said. Throughout the Lincoln area, Wentz is known for using his courses as both a learning experience for his students as well as a way of serving the community. It’s not surprising to learn that the MCAA chapter at UNL was named MCAA Student Chapter of the Year in 2005.
Each semester, Wentz uses his Construction Management courses to improve community buildings in the campus area. “I incorporate a ‘service learning’ component,” said Wentz. “We find buildings with significant mechanical problems and spend the semester addressing the problems.” Past projects have included doing rehab work on churches and rehabilitation centers.
“When Dan Holtmeyer contacted us, we were very familiar with Professor Wentz and his work with the MCAA Student Chapter so we knew their request was a worthwhile cause,” said Mark Handzel Director of HVAC Sales at ITT. Education has always been important to ITT. For years, we have been a strong supporter of schools who are preparing students for careers in engineering. We are pleased to have had the opportunity to assist the University of Nebraska at Lincoln with this most recent donation.”
The Bell & Gossett VSC Pump will be used in the Spring 2007 semester at the University of Nebraska at Lincoln, for the Building Environmental Systems, Mechanical Estimating and Mechanical/Electrical Project Management courses.
ITT is a major manufacturer of pumps, heat transfer, packaged systems and controls for HVAC, plumbing and fire protection applications.
