NOTE!
Decreasing pump output!
In the event of decreased pump output, Börger GmbH rec-
ommends first checking the condition of the rotors.
Replace the rotors when they exhibit signs of significant wear
.
— If these measures are not successful and the original pump
output is still not reached following the installation of new
rotors, the casing protection plates must be inspected.
If one of the gear-side and cover-side casing protection plates
exhibits significant signs of wear, it must be replaced, whereby
the cover-side casing protection plate can be turned once before
replacing it.
If a gap still remains between the rotor body tips and the radial
casing wall following the installation of new rotors – while the
pump output remains too low – then we also recommend
replacing the pump casing.
Before replacing wear parts, take advantage of the possibility of
increasing the speed of the pump drive (and thus, the pump
output).
— On electric motors, this can be an increase in frequency on
your frequency converter (this can also be above the mains
frequency). For example, the speed can be varied on some
drive types by adjusting the drive speed (hand wheel on the
control gear motor or gas lever on the combustion motor) or
oil quantity (on hydraulic drives).
— Observe the maximum loads in
Ä
Chapter 3.3 “Technical data
” on page 49.
— If in doubt, contact Börger customer service regarding the
physical limitations of your unit.
