When 450 Lexington Ave in New York City had issues with its existing triplex domestic water booster system,  Joe Petro, a top engineer at  Concessi Engineers, was called in to examine the system. Joe looked at the system which had three horizontal multistage constant speed pumps from a well known competitor.  After assessing the situation, Joe called in Callaghan Pump and Controls recognizing that its variable speed pumps would be a viable solution to the existing problem.  The problem with the previous  booster system was that it either ran at full speed or was off. When the building's water demand was very low, the pumps had a ten minute minimum run timer, which boiled the water, causing premature failure of the mechanical seals.  To make matters worse, the pumps had a minimum flow requirement of 20 gallons per minute.  Both of these issues were handled with a "bandaid" known as a solenoid valve which dumped water to a drain wasting water and the pump's energy.  The solution was to replace the system with higher efficiency pumps and variable speed Hitachi drives controlling premium efficient motors.

Callaghan Pump and Controls replaced the old system with a triplex equal split 150 hp triplex variable speed system similar to our Quantumflo VMS system. With the help of Eamon Devlin of Kinturk Contracting, the system was moved into place in under 4 hours and Par Plumbing piped out the system  Its compact design allowed the system to be installed behind the existing system in a space of 36" x 72". When startup and testing was complete the old 72" x 121" system was removed and discarded. Not only did the owner pick up valuable NYC real estate in the mechanical room, but hearing protection was no longer necessary as the old system sounded like a jet airplane running and the new system with vfd's sounded more like an electric car. The unexpected  surprise benefit of the system was a reduction to  the electric bill  of $2,470.00 a month.  As it turns out, the owner gained all around: more space,  less noise , and  less expenditures.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

780 3rd Avenue was a fantastic project in so many ways. When we arrived on the scene, the existing pump systems consisted of a duplex high zone domestic water and cooling tower makeup and a triplex low zone domestic water system. All 5 pumps were constant speed with minimum run timers and pressure regulating valves (PRV's) total horsepower was 225 combined.  These constant speed systems in a high rises are often accompanied by nightmare stories of blown mechanical seals and mechanical solenoid valves dumping water to satisfy minimum flow requirements of the pumps. Variable speed drives eliminate these problems.

While the old system stayed operational,  a quadraplex pump system Identical to Quantumflo's Whisperflo model was slid into place and installed by Steven Silver of American Pipe and Tank.   225 horsepower of pumps  was replaced with a system of 175 hp.  Not only were the the horizontal multistage pumps replaced with 16 percent higher efficient Grundfos pumps, but also  premium efficient motors and 4 Hitachi variable speed drives were included to bring the operation costs to an all time low.  As is usually the case, a variable speed system was was able to free up  200 square feet in Manhattan real estate because the new system mounted to the wall. Also, the new system led to a savings of $2,800.00 of electric per month. An additional benefit is the ability to talk at a normal db level because the pumps  used in this building are surrounded by water in a stainless steel tube. Consequently, the pumps can't be heard, only the drives.
