Flygt 2600 sludge pumps from Xylem (spun off from ITT Corp. in October), are capable of flows to 450 gpm and heads to 128 feet. The wear-resistant pumps can handle up to 3.2-inch solids and sand concentrations of about 20 percent by weight. Applications include pretreatment sand trap pumping, digester cleaning, and temporary sewage pumping.
Features include the Hard-Iron (60 HRC) vortex impeller and polyurethane-lined housing for extended service life, Plug-In single-cartridge double mechanical seal, external oil and inspection plugs, and watertight terminal board. A removable top provides access to electrical components, while an air valve releases air pockets from the cooling jacket. An adjustable side discharge allows for larger solids passage and vertical or horizontal discharge.
“The key differentiator of the 2600 sludge series is their versatility,” says Peter Hansen, product manager. “They are particularly useful for pumping larger solids, mostly at temporary installations or in maintenance situations.” Available in three models (2620.280, 2630.280, 2640.280), the portable dewatering pumps weigh 75 to 123 pounds. Options include manual and automatic starters, outlets for side discharge hose or threaded connections, and SUBCAB submersible cable.

The 2620 50 Hz models have a 1.5 kW single-phase/2.2 kW three-phase motor and can handle solids up to 50 mm. The 2630 has a 3.2 kW motor and can handle solids up to 80 mm, and the 2640 has a 5.6 kW motor and can handle solids up to 46 mm. The 2620 60 Hz models have a 1.8 kW single-phase/2.6 kW three-phase motor and can handle solids up to 50 mm. The 2630 has a 4.5 kW motor and can handle solids up to 80 mm, and the 2640 has a 9.6 kW motor and can handle solids up to 46 mm.
Accessories include level regulators that control pump operation or actuate an alarm, pump raft that keeps the pump afloat, zinc anode kits for extra corrosion protection, pump integrated memory (PIM) that records pump performance and service-related information, and the FPC 100 pump control system that automatically monitors and controls the pump without the use of level sensors. The pumps can be rented for once-off projects, such as emergencies or plant maintenance, reducing costs during tight budgetary times. 856/467-3636; www.xyleminc.com.
