Eccentric Screw Pumps
Series AE1E, AE2E
Design ID

Application
For handling liquid to highly viscous, neutral or aggressive,
uncontaminated or abrasive liquids, liquids containing gases or
which tend to froth, also containing fibres and solid matter.
In waste water and waste water treatment engineering, chemi
cal and petrochemical industry, paper and cellulose industry,
soap and fats industry, paint and lacquer industry, food and
beverage industry, plastics industry, ceramics industry, agricul
ture, sugar industry and in shipbuilding.
Function
Self-priming, single or two-stage, rotary positive displacement
pump. Conveying elements are the rotating eccentric screw
(rotor) and the fixed stator. In the cross-sectional plane, both
are in contact with one another at two points forming two
sealing lines along the length of the conveying elements. The
contents of the sealed chambers which are formed as the rotor
turns are displaced axially and with complete continuity from
the suction to the delivery end of the pump. Despite rotor
rotation, there is no turbulence. The constant chamber volume
excludes squeezing, thus ensuring an extremely gentle low
pulsating delivery.
Structural design
By external casing connecting screws (clamping screws), the
pressure casing, stator and suction casing are interconnected.
The suction casings are designed particularly favourable to
flow. The pump sizes 200 to 9500 in cast iron design are pro
vided with staggered holes for cleaning. The sizes between
50 and 1000 will be supplied in a cast iron finish as an alterna
tive with an suction casing with a square intake controller. The
stator vulcanized into a tube or shell casing (even elastomer
wall thickness) is provided with external collars vulcanized to it
on both sides reliably sealing towards the suction casing and
delivery casing and protecting the stator shell from corrosion.
Stators are supplied:
with uneven wall thickness:
single-stage for all sizes,
two-stage not for sizes 550, 1000, 5000, 9500
with even wall thickness:
single-stage not for sizes 50, 550, 1000, 9500
two-stage only for sizes 100, 200, 380, 750, 1450
The exchangeable shaft sealing housing or mechanical seal
housing (subsequent conversion to another sealing variant is
possible) are arranged between the suction casing and bearing
bracket. The sealing housings (shaft seals) are easily accessible
as the complete bearing unit can be withdrawn from the driving
shaft without any further pump dismounting.
Bearing of the driving spindle is effected in the bearing bracket.
The torque of the drive is transmitted over the driving shaft and
the joint shaft onto the rotor. On both sides, the joint shaft ends
in liquid-tight encapsulated bolt joints, which are designed par
ticularly simple and sturdy properly taking the eccentric move
ment of the rotor.

Shaft seal
By uncooled, cooled or heated stuffing box or by uncooled or
cooled maintenance-free unbalanced, single or double-acting
mechanical seal.
Material pairing and design are adapted to the respective
operating conditions. For further data, refer to pages 4, 5.
The stuffing box or mechanical seal housings of the various
shaft sealing types are interchangeable within one size. The
various mechanical seal housing parts form a modular con
struction system and, in case of conversion to a different
mechanical seal design, can be easily combined with one an
other.
Installation spaces for mechanical seals according to
DIN 24 960 (except for double mechanical seal).
For further data, refer to pages 4, 5, 6 and 7.
Technical data
Deliveries, admissible speed ranges and required drive powers
are to be taken from the performance graph on page 3 and/or
the separate individual characteristic curves.

quotation or order acknowledgement.
Max. admisslible grain sizes and fibre lengths
Size 50 100 200 380 550 750
max. grain size mm 3 3,8 5 6,8 6,8 9,5

max. fibre length mm 98 130 210 250 250

Increasing solids content and increasing grain size require a reduction of the pump
speed:
depending upon the fluid to be pumped and the elastomers employed.
10 bar for stator with even elastomer wall thickness.
depending upon the pump size/design, speed, fluid to be pumped.
6 bar for shaft with shaft sleeve.
depending on direction of rotation, inlet pressure.
For suction casing with a square intake controller and worm screw
on the articulated shaft.

Drive
Driving possibilities see page 12.
Drives of any manufacturers can be employed. For the techni
cal data and dimensions, please refer to the documents of the
manufacturers.
Installation
AE pumps may be installed horizontally or vertically. In case of
vertical arrangement, “shaft shank downwards?is not admis
sible.
By means of a flexible coupling or via a gear (as a rule, V-belt
drive), the pump and drive are connected with one another and
mounted on a common base plate. For aggregate dimensions,
please inquire.
