Compact perfection
The proportion between the length and width of the
shaft in the pump is extremely important. Large
shaftdiameters(D)andashortdistancefromimpeller
to motor (L) maximizes stability and ensures lower
maintenance costs. Grundfos pumps always strive
for the most optimal proportion between the length
and width of the shaft (L

GrundfosBlueux®IE3
Grundfos Blueflux® motors as
standard in both TP and TPE pumps.
Onlymotorswiththeocial

Anti-corrosionsurface
Cataphoresis surface treatment consisting
of Powercron® cathodic electrocoating and zinc
phosphate coating.

Theall-in-onesolution
In Grundfos TP/TPE pumps, coupling and shaft have
been friction-welded together to create a completely
stable mechanical unit, which drastically reduces the
vibration levels. The stability of this all-in-one solution
prolongs the lifetime of both shaft seal and bearings.
