New Multi-purpose Sludge Pumps Enhance the Flygt 2600 Drainage Range
ITT Corporation introduced a new sludge series to its flagship Flygt 2600 drainage pump range. Available for rental or purchase, the new Flygt 2600 sludge series comprise three portable multi-purpose models that handle sludge and other liquids containing larger solids.
This extension provides a versatile and functional range that meets the evolving requirements of drainage and wastewater transfer applications for construction, mining, tunneling, industrial, and municipal customers. In addition, the pumps have new features which are easy to install and service, which reduces the total cost of ownership.
The three new Flygt sludge 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 (450 GPM) and heads to 38 m (128 ft.), 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.
The Flygt 2600 sludge pump series – models 2620.280, 2630.280, and 2640.280 – results from customer demand for multi-purpose drainage pumps. These wear-resistant pumps handle solids up to 80 mm (3.2 in.) in size and solids concentrations of approximately 20 percent by weight, due to a larger inlet and pump volute, Hard-IronTM (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 ITT’s Water & Wastewater business. “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-InTM 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 screwless spring-loaded terminal design assures reliable connections and simplified wiring.
