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 The sealing housings (shaft seals) are easily accessible as the complete bearing unit can be withdrawn from the driving shaft without any further pump dismounting.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.

250 | Increasing solids content and increasing grain size require a reduction of the pump speed: ➀ depending upon the fluid to be pumped and the elastomers employed. ➁ 10 bar for stator with even elastomer wall thickness. ➂ depending upon the pump size/design, speed, fluid to be pumped. ➃ 6 bar for shaft with shaft sleeve. ➄ depending on direction of rotation, inlet pressure. ➅ For suction casing with a square intake controller and worm screw on the articulated shaft. 1 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.
