One of the primary aspects of our company that makes Metropolitan Industries an ideal partner for business is our dedicated design and service staffs. No matter how complex your job may be, Metropolitan is determined to meet your needs and requirements. At times we are faced with projects in which strict specifications must be followed. We take customer specifications with great seriousness and can customize projects to meet important guidelines.
A premier example of our ability to provide customized solutions can be illustrated by the work done at a large municipal water treatment facility that conducts o-zone generation.
Metropolitan was first contacted by Symbiont Science, Engineering & Construction, Inc. in 2011 to provide a Metro-Varipac triplex booster pump system to supply cooling water to the facility. The existing pressure boosting system the customer had been using ran at a constant speed. Metropolitan implemented the triplex system with a design point of 300 GPM at 185.5 feet of TDH to become the primary system. The system runs at a maximum of 425 GPM at 120 feet of TDH, and each pump is rated at a minimum of 25 HP. A 200 PSI rated hydropnuematic pressure tank was also included.
Project specifications called for custom programming.
“One of the unique aspects of Metropolitan is our ability to provide both standard and custom programmed controls,” said Metropolitan salesperson Tim Laskowski. “This particular project was very job and system specific, but we were able to supply everything the customer needed.”
Metropolitan was also able to provide the customer with a specialized startup and certified test of the system on-site. A flow meter and all certified pressure gauges were included to meet project specifications and Hydraulic Institute standards.
Metropolitan’s Paul Larson, P.E., said stainless steel features were added to the system to provide corrosion resistance.
“We integrated a stainless steel skid, stainless steel control panel and galvanized piping which will prevent corrosion, and thus extend the life of the system,” said Larson.
The system also came complete with variable frequency drives, eliminating the constant speed control the previous system had utilized. Variable speed controls can save customers thousands in energy savings and eliminate the need for pressure reducing valves.
“Metropolitan is completely dedicated to providing energy efficient products to our customers,” said Laskowski. “We can design systems to pump at the lowest possible pressure, which saves in energy costs and can even pay for an entire system with savings accumulated over time.”
Project engineer Pat Carnahan of Symbiont said Metropolitan’s ability to test a system on-site was a nice change of pace when working on this type of project.
“It was a welcomed experienced to work with a vendor with skilled people who can think on their feet,” said Carnahan. “The test went very well and we were able to verify the majority of the control features during one day of testing.”
Carnahan also noted that Symbiont was pleased to find that the pump skid was constructed and delivered to their precise layout and control requirements.
“In the past we’ve purchased pump skid systems and our specified control sequences were not provided,” said Carnahan. “A level of comfort was established with Metropolitan on this project because the system supplied matched our specifications and expectations.”
Part of Metropolitan’s commitment to customer service is sharing our expertise with customers, operators and engineers. Metropolitan provided on-site training for the customer to ensure the transition from the previous system to the new system was proficient and easy.
Overall, Laskowski said the project demonstrates Metropolitan’s flexibility and dedication to providing customers with projects that match precise requirements.
“This job illustrates how we’re able to handle whatever comes at us and get the job done correctly,” said Laskowski. “We take the specifications seriously and we’re very careful in supplying exactly what the customer has asked for at a very competitive price.”
