Multi-Purpose Sludge Pumps Further Enhance Xylem’s Dewatering Portfolio
Xylem, a leading global water technology company focused on addressing the world’s most challenging water issues, now boasts one of the most extensive portfolios of dewatering pumps on the market with the addition of three new sludge pumps to its flagship Flygt 2600 drainage range. The company, which was spun off from ITT Corporation on October 31, 2011, specifically designed these versatile pumps (models 2620.280, 2630.280, and 2640.280) to meet customer demands for multi-purpose drainage pumps that can serve the evolving needs of the mining, tunneling, municipal, industrial, and construction markets. Available for rent or purchase the pumps have new features which are easy to install and service, reducing the total cost of ownership.
The portable Flygt sludge 2600 pumps have a range of 1.5 to 5.6 kW for 50 Hz countries and 2.4 - 8.9 hp for 60 Hz countries. Capable of flows up to 28 l/s and heads to 38 m, these sludge pumps are ideal for temporary sewage pumping, digester cleaning at wastewater treatment plants, light slurry transfer, open-pit and underground mine dewatering and emergency site drainage.
These wear-resistant pumps handle solids up to 80 mm and sand concentrations of approximately 20% by weight, due to a larger inlet and pump volute, Hard-Iron™ (60 HRC) vortex impeller, polyurethane-lined pump housing and side discharge design.
“These highly versatile pumps can move sediment-filled water from a construction site, pump light slurry in an aggregate washing process or remove water and drilling mud mixtures from the face of tunnel boring machines,” says Peter Hansen, product manager for Flygt drainage pumps at Xylem. “And because the hydraulics of the sludge pumps and drainage pumps are interchangeable, customers can adapt one 2600 pump to handle many applications.”
The hydraulic ends of the new sludge pumps share drive units and common parts, and are interchangeable with similar sized models of the 2600 drainage series. This interchangeability allows end users the flexibility to adapt to changing application requirements and reduce spare parts inventory.
Flygt customers already familiar with the easy-to-service 2600 design will find maintaining the sludge pumps just as simple and quick. The new sludge series features the patented Flygt Plug-In™ seal, which provides a double mechanical seal in a compact and easy to replace single cartridge. External oil and inspection plugs, allow for seal-condition check and oil change without dismantling the pumps, and the removable top gives quick access to all electrical components.
The three new models also incorporate the latest enhancement in Flygt pumps: the terminal board. By sealing off the junction box from the motor, the terminal board prevents any water from passing between compartments, thereby reducing repair costs. Plus the screw less spring-loaded terminal design assures reliable connections and simplified wiring.
Another recent addition to the Flygt drainage range is the two-stage Flygt pump 2660 SH. Twin impellers enable the 2660 SH to pump fluid higher. With 10 kW rated power the 2660 SH can be used in a broad range of applications within the construction and mining industries. A zero leakage 'Active Seal' increases the service life of the pump and contributes to longer intervals between oil changes and maintenance check-ups. A unique hydraulic system developed by Xylem, the ‘Dura-Spin’ effectively protects the impeller gap by transporting abrasive particles outwards. A Spin-Out system includes a special design of the seal chamber. Solid particles will be transported via a spiral groove in order to protect the seals and the bottom of the oil housing from sediments and wear.
Xylem is a leading global water technology provider, enabling customers to transport, treat, test and efficiently use water in public utility, residential and commercial building services, industrial and agricultural settings. The company does business in more than 150 countries through a number of market-leading product brands, and its people bring broad applications expertise with a strong focus on finding local solutions to the world’s most challenging water and wastewater problems. Launched in 2011 from the spinoff of the water-related businesses of ITT Corporation, Xylem is headquartered in White Plains, New York.
The name Xylem is derived from classical Greek and is the tissue that transports water in plants, highlighting the engineering efficiency of our water-centric business by linking it with the best water transportation of all -- that which occurs in nature.
