Heavy-duty design features for tough wastewater services:

• Externally adjustable rotating assembly

• Permits easy renewal of critical operating clearances and pump efficiency.
• Heavy-duty bearings

• For superior L10 bearing life.
• Back pull-out design

• Eliminates the need to remove casing from piping.
• Sealing flexibility

• A wide range of sealing options are available to suit the application including packing, double mechanical seal, cartridge mechanical seal, or Equiseal™ dynamic seal.
• Universal stuffing box

• Accepts packing or mechanical seals. Makes converting shaft sealing methods in the field easy.
• Clean-out port

• Hand hole clean-out port is standard on casing (and suction nozzle when applicable). Provides for easy inspection of, and access to, impeller.
• Mounting flexibility

• Several horizontal and vertical mounting arrangements available for various installation options.
• Discharge flexibility

• Tangential discharge for passing solids easily without clogging the nozzle. Discharge nozzle can be rotated to any one of eight positions to suit the piping layout.
• Casing connections

• All vent, drain, and gauge connections are standard on Flygt non-clog pumps.
• Non-clog impellers

• Available in either clockwise or counterclockwise rotation. Designed to pass large, soft, solids with maximum efficiency and without clogging.
• Tapered shaft

• Tapered shaft/impeller fit will not loosen and hence reduces vibration. Also makes disassembly much easier than straight shafts.
• Contoured impeller nut

• Impeller nuts are contoured to prevent material from hanging up. Secured with stainless steel set screws to prevent backing off.
• Suction cover wear plate

• Hardened 400 Series stainless steel wear plates are standard on NS models to protect casings from erosion.

ITT Flygt's non-clog pumps are designed to handle wastewater and other non-corrosive liquids with soft solids in suspension. Typical applications include municipal and industrial wastewater treatment, food processing, and storm water run-off.

Features:

EQUISEAL™ Dynamic seal

• Packing and expensive mechanical seals are eliminated
• Seal flush is not required thus conserving water and eliminating retreatment costs
• No metal-to-metal rubbing parts and no critical operating clearances means significantly longer life than other sealing methods
• Static seals prevent leakage when pump is not operating
• Packed or mechanically sealed pumps can be easily converted in the field

Shearpeller™

• Available on pumps up to 8"
• Made of high impact 431 stainless steel
• Larger solids handling capability than standard non-clog impellers
• Capable of handling fluids with high percentages of suspended solids
• More efficient than pumps with fully recessed impellers
• Ideal for digester sludge and grit service

Impeller wear ring

• Made of hardened 400 series stainless steel
• Protects impeller from erosive wear
• Easily replaceable for renewal of operating clearances and efficiency
• Provides up to 0.25" of wear allowance
• Optional on NSW, standard on all other models
