Shredder Pumps Installed at Historic Ellis Island BJM's SK Series Electric Submersible Pumps with Shredder Action gets antiquated system back on line after Hurricane Sandy and keeps busy tourist attraction up and running.   The Facility   Ellis Island, in the shadow of the Statue of Liberty, is one of America's most popular historic sites. The island is one of a number of small, naturally occurring islands in New York Harbor. Over many years, this island — which for millions of people represented the gateway to the New World — was enlarged from its original 3.3 acres to its current 27.5 acres by adding landfill from ships ballast and possibly excess earth from the construction of the New York City subway system.   The island was not always a point of entry for immigrants or a tourist destination. By the time it was purchased in the 1770s by Samuel Ellis, it had served as a hanging site for pirates, a harbor fort, and an ammunition and ordinance depot. The US Government purchased the island from New York State in 1808. Just before the War of 1812 broke out a series of structures were erected that served as a defense system for New York Harbor. Ellis Island was approved as a site for fortifications and on it was constructed a parapet of three tiers of circular guns.   In January 1892 Ellis Island was opened as an immigration station. Over the next 62 years more than 12 million immigrants were processed at the site. After World War I immigrants applied for visas at American consulates in their country of origin, and the only immigrants passing through Ellis Island were those who had problems with their paperwork, war refugees and displaced people. Ellis Island was officially closed as an immigration station in 1954.   In 1965 President Lyndon Johnson declared Ellis Island part of the Statue of Liberty National Monument, and in 1984 Ellis Island underwent a major restoration—the largest historic restoration in U.S. history. In recent years the island has become one of the most popular tourist destinations in the National Park Service. That means a lot of visitors and the need for well working infrastructure. On October 28, 2012, Hurricane Sandy swept over Ellis Island, Liberty Island, and much of the East Coast. The Ellis Island Immigration Museum reopened on a limited basis one year later, but repairs to the buildings and infrastructure would continue for many months.   The Challenge Although the damage to Ellis Island was extensive, the island's antiquated sewage system was fraught with problems long before Hurricane Sandy came ashore. New Jersey-based Pump Express Services  had been providing maintenance to the island's sewage ejector system for a couple of years before Sandy hit.   According to Pump Express [and Pump Products] sales manager Fred Hettinger, in the two years before Sandy they were called to the island numerous times in response to high water alarms, clogging and ultimately a failed pump. "They had a two-pump system and when one pump failed they let the system run on the other," Hettinger said. Then, the second pump failed "and they had nothing."   Hettinger explained that a significant problem was that the old pumps were a simple ejector type and didn't break down solids. But along with the sewage flow on the island there was also a significant amount of debris—with synthetic fibers being particularly problematic—that routinely clogged the system.   Left with only minimal sewage disposal, and faced with a grand reopening to the public targeted for July 4th, 2013, the island's maintenance engineers reached out again to Pump Express Services—this time for a more permanent solution.   The Solution   "We submitted a proposal to replace the old pump system with a pair of 15 horsepower BJM shredders," Hettinger said. "We've been using BJM shredders for four or five years now and everything we've been able to throw at them they've been able to handle."   In April 2013 Pump Express installed a pair of 900-pound SK Series shredder pumps into the revamped Ellis Island system. The pumps can handle 845 gpm of wastewater at heads of up to 94 feet. The SK Series pumps were chosen specifically because they are designed to shred solids before passing the liquid. The shredder pumps leave solids slightly larger than if they were passed through a grinder pump. The shredding action is produced through use of a unique FangTM  non-clog cutting impeller with tungsten carbide vane tips against a high-chrome "tooth shaped" diffuser plate. The cutting tips shred solids against the pump suction plate, continuously ripping the solids apart with 360o shredding action. The SK Series shredder pump works on many objects that would clog an ordinary pump.   Other quality features built into the SK Series pumps  that supported their recommendation for the Ellis Island installation include the following: The 304 stainless steel motor housing helps protect the pumps from abrasion and premature wear caused by the harsh saltwater environment. The motor is protected by double mechanical seals. The lower seal is made of silicon carbide/silicon carbide and the upper seal is made of carbon/ceramic. In addition, a lip seal has been installed above the impeller that helps prevent abrasives, such as sand, from entering the seal chamber. Winding protection and NEMA Class F motor insulation allow the motor temperature to rise to 230oF. An automatic switch turns the pump motor off if the temperature and/or amp draw gets too high. When the motor cools the switch will automatically reset and the pump will restart. A hardened cast iron exterior stands up to rough handling and pumping of sandy water unlike pumps with soft resin impellers or plastic exterior components. (Specifications may differ between models.) The Conclusion   About six months after installation a team from Pump Express went back to Ellis Island to make sure the new pumps were performing as anticipated. "We're now going on a year and a half and haven't had any issues," Hettinger said. That's a vast improvement over the previous average of a visit every six months. "I bet in the last 18 months if we had had to go out there three more times it would have cost them half of what the upgrade cost them," he added.   Pump Products currently stocks the Following BJM pumps: Dewatering Pumps High Temp Pumps Marine Pumps Shredder Pumps Solids Handling Pumps   For more information on BJM residential and commercial pumping equipment, visit Pump Products at  www.pumpproducts.com or call 1-800-429-0800 Also, check out our service department  by visiting Pump Express Services or call  1-800-620-7331 Read Original Article At: BJMPUMPS.COM Download The Original Article. Download PDF

An in-line circulator pump, or 3-piece circulator, is comprised of three main components: The volute, the motor and the bearing assembly. So what are the three most commonly repaired parts on a 3 piece circulator Bearing Assemblies Seals Couplers A bearing assembly connects the pump motor and volute via a shaft on each end. Bearing assemblies must be periodically lubricated to ensure proper operation unless they are self-lubricating or "maintenance-free." Because they have many moving parts and are in constant use, they are prone to wear and are commonly in need of replacement. A turning motor that isn't pumping water probably has a worn-out bearing assembly. Fortunately, bearing assemblies are easy to replace and Pump Products carries replacement assemblies for many popular pump models. We have a large selection of Bell & Gosset bearing assemblies  & Armstrong Bearing assemblies in stock and available for next-day delivery.

Solar energy is renewable energy. It’s source, sunlight, is as plentiful after 20 years of use it is on the day you harness it to heat your home. Best of all, it’s environmentally benign and unlimited in supply. The cost of a solar energy system depends on the amount of energy it generates, the system’s design, installation fees and components. Solar energy systems depend on photovoltaic panels. A photovoltaic (PV) panel is basically a solar-powered, direct-current (DC) battery that captures the energy of sun. The greater a system's demands, the larger it's PV network has be. (more…)
