Applications
For other applications than mentioned below, contact
your nearest Flygt representative for information.
Mixer
The mixer is intended to be used in:
— sewage plants, sludge tanks and aeration basins,
anaerobic or oxygen saturated water, presence of
rags etc.
— industrial processes, heavy environments with high
demands of operational security, water with usually
metallic salt, paper pulp and cellulose, food and
chemical industry.
— industrial sewage processes, some wearing, pres-
ence of rags and metallic salt.
— mineral slurries with high wearing characteristics,
presence of rags acceptable.
— fish farms and current creating in dams, oxygen
supply, demands of environmental approved mate-
rials. Sweet, brackish or salt water.
— liquid manure, presence of straw, strings, board-
pieces etc, floating sludge with a thickness of up to
1 meter (3.3 ft).
The mixer is designed for use in many different situa-
tions where high flow capacity in relation to power
consumption is required.
The mixing effect is dependent upon the density and
the viscosity of the liquid and on the volume/shape of
the tank.
More than one mixer is required for larger tanks.
Flange mounted mixer
The flange mounted mixer is intended to be used in:
— Oil industry/oil tanks.
— Pulp and paper industry.
— Various process industry.
PP-pump
The PP-pump is intended to be used for:
— clean water pumping at land drainage,
— irrigation and controlling of water course systems,
— waste water treatment, recirculation within treat-
ment processes or return sludge pumping.
The hydraulic parts together with the installation ac-
cessories are specially designed to optimize the per-
formance of the pump.
PRODUCT DESCRIPTION
General Description

series have the below features:
— direct driven electric multipole motors.
— propellers with different diameters and blade
angles.
— different materials.
— different seals.
— different installation modes.
The pH of the liquid: 1—12.
Liquid temperature: max. 40°C (105°F).
Warm liquid version max. 90°C (195°F).
Depth of immersion: max. 20 m (165 ft).
Only Ex-approved machines may be
used in explosive or flammable
environments or for mixing/pumping
flammable liquids.
