4.1 Description of glandless
pumps
The pump is of the canned rotor
type, all rotating parts thus being
immersed in the fluid being handled.
A shaft seal, being a part prone to
wear and tear, is not required. The
fluid lubricates the shaft bearings
and acts as coolant to bearings and
rotor. The pump is thus mainte-
nance-free and has a high life
expectancy.
Twin pumps contain two identically
constructed pump heads in a com-
mon housing with integrated non-
return flap. Each pump can operate
independently or both pumps simul-
taneously in parallel. Standard ope-
rating modes are main/standby or
base-/peakduty. The pump heads
can be selected of different capaci-
ties. Twin pumps are suitable of
adapting a pipe system to suit indi-
vidual load characteristics.
