1 / 3F 3171 Industrial — product view; equipment may vary by configuration.
F 3171 Industrial
Chopper pump for industrial fibrous waste
Flygt F 3171 Industrial is designed for industrial waste with high dry-solids content and long fibres. An S-shaped impeller works with a back-vane housing cover and inlet cover. An optional cutting knife is available for fish-processing and aquaculture applications, while a clutch helps protect the shaft during serious blockage. The 50 Hz three-phase options are 7.5, 9 and 13.5 kW with four poles, or 8.8 kW with six poles. It is a distinct industrial configuration from the standard N-technology F 3171.
Final performance and suitability are verified for the selected model and duty point.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Fish and poultry processing waste · Liquid manure and biogas processes · Food waste and paper industry
Selection considerations
Establish solids size, fibrous content, sump geometry and minimum liquid level. Drainage and sewage pumps have different application limits.
Share your operating conditions with our technical team. We can assess liquid compatibility, hydraulic duty point and installation requirements together to identify the suitable variant.
