WASTEWATER CHOPPER PUMP WITH N-TECHNOLOGY

The Flygt F 3171 pump features patented Flygt N-technology, which is renowned for its self-cleaning capabilities and sustained high efficiency. The chopper pump performs like no other, handling whatever goes down the drain — from plastic bottles and wood to clothing and other debris.

Flygt F pumps feature the patented Flygt N-impeller, which rotates inside a chopper insert ring. This rotation cuts all types of hard-to-pump solids, such as fibrous material, textiles and other debris, into small, easy-to-pump pieces. The well proven Flygt F-pump demonstrates unmatched reliability in installations worldwide.

Cost-effective operation 

The Flygt F 3171 pump transports tough solids and reduces operation and maintenance costs. Under extreme conditions, our energy-efficient chopper pumps run continuously with sustained hydraulic efficiency in heavy-duty applications such as:

• Heavy-duty wastewater applications

• Food processing facilities

• Pulp and paper mills

• Heavy-duty sludge pumping

• Aquaculture

• Agricultural facilities

• Correctional facilities

• Public access facilities

ENGINEERED FOR LONG LIFE

• Replaceable chopper insert ring made of Hard-Iron™ material for tough wastewater applications where cutting is required

• Hard Iron™ impeller suitable for cutting demands and with exceptional wear resistance in tough wastewater applications

• Short shaft overhang reduces shaft deflection and increases seal and bearing life

• Motor designed for submersible use. Heat is concentrated to the stator core for improved cooling properties.

• Plug-in™ seal with Active Seal™ system eliminates the risk associated with incorrect installation and careless handling presented in one easy to handle unit. Available in Tungsten carbide (WCCR) or Silicone carbide (SiC) depending on pumped media.

• Motor cable SUBCAB® specially developed for submersible use.

• Flexible cooling system: closed loop cooling system, media cooled or external cooling, for handling a wide variety of situations
