AFU Series features
Choose from two pole, four pole and large-solids versions, all in heavy-duty cast iron.
Sealed cable entry
An epoxy resin cable base stops moisture getting into the motor through the core wires.
Automatic motor protection
An automatic on/off protector stops the motor burning out from high temperature or excess current. Standard on pumps up to 10 HP (7.5 kW).
High-efficiency dry motor
Varnish-insulated stator coils for good insulation, efficiency and durability.
Double mechanical seals
Abrasion-resistant silicon carbide seals run in an oil housing, independent of the pumped liquid.
High-solids epoxy coating
A coating over 70 µm thick protects the cast iron from salty water, industrial wastewater and chemicals.
Recessed vortex impellers
The impeller sits back from the flow, so water containing large solids passes through without clogging.
Large-solids versions
L models pass solids up to 50 or 76 mm; four pole 100 mm models pass up to 100 mm.
Two or four pole
High-torque two pole or four pole motors, to suit the head and flow you need.
Quick coupling
Install on a duck foot bend for easy installation and service. An adaptor bracket fits Flygt and Tsurumi duck foot bends.
