Premium products
in order to provide reliable pumps, Flygt both designs
and manufactures pump motors, which are designed
for powering the hydraulics of a pump unit. powering
a hydraulic part of a pump unit for submersible duty
has certain requirements on the motor design. For instance,
cooling of a standard motor is generally handled
through the use of fans. A submersible pump motor,
on the other hand, is cooled either by the surrounding
media or by a cooling jacket with liquid cooling media
inside, which in turn exchanges heat with the surrounding
media.
Manufacturing of Flygt motors.
Flygt pump motors are designed and manufactured to
operate under these conditions in reliable and effective
way. Having complete knowledge of the motor characteristics
implies start calculations with high accuracy
motor function using all types of start methods.
