This manual contains installation, operation, assembly, disassembly and repair instructions for
the Fristam FL2 15, 58, 75, 100 & 130 models rotary pump and the Fristam FL3 versions of
these models.
Fristam FL2 Series bi-wing rotor pumps are positive-displacement pumps with non-contact
rotors.
Fristam’s FL2 Series bi-wing rotor design combines mechanical simplicity with pumping effi-
ciency. The pump’s bi-wing rotor provides easy maintenance, cleanability, gentle product han-
dling and dependability. With nine pump models and a full range of options, you can match
your process needs precisely.
The FL2 Series pump is available with any connection type desired and may be mounted
with the inlet/outlet connections in a horizontal or vertical orientation. The pump should be
coupled to a motor/drive assembly properly specified to give the desired performance for the
required application.
The FL3 Series pump is a version of the FL2, featuring unique helix-shaped tri-wing rotary
lobes, providing increased suction capabilities and virtually eliminating pulsation and reduc-
ing noise.
