4.4.6 Non-ionizing radiation (EMC)
No non-ionizing radiation, such as from
magnetic fields, is emitted from the
progressing cavity pump.
4.4.7 Operation
Self-priming, rotating displacement pump. The
pumping elements are the rotor and the fixed
stator. The rotor and stator contact each other
at two points of their cross-section on series
AE1.F, AE.E, AE.N, AE.H, AE.V and at three
points on series AE1L, AED1E, AED2N. When
viewed over the length of the pumping
elements, these two or three points form an
equal number of sealing lines along the length
of the pumping elements. As the rotor turns,
the contents located in the resulting sealed
chambers are moved axially and continuously
from the suction to the pressure side of the
pump. Despite rotation of the rotor, no
turbulence results.
The consistent chamber volumes eliminate
crushing forces and ensure an extremely
gentle, low-pulse pumping action.
4.5 Pump unit design
4.5.1 Drive
Driven by electric motors with or without
explosion protection, gear motors, or variable
gear motors. Other drive types, such as with a
V-belt, are possible.
4.5.2 Shaft coupling and safety
guarding
Shaft coupling according to DIN 740.
A safety guard according to DIN EN 809 is
attached whenever pump, base plate, and
shaft coupling are delivered together.
Warning!
Danger of being caught, wound,
drawn in and trapped.
In accordance with accident-
prevention regulations, the pump
may be operated only with safety
guarding according to DIN EN 809!
► If safety guarding is not
included, the operator must
install safety guarding.
4.5.3 Base plate
Horizontally-installed pumps are usually
installed with the drive on a shared base plate.
Unless specified otherwise by the operator, the
base plate is made of steel.
