1 Eccentric Screw Pumps ALL-OPTIFLOW SERIES AEBF Design IE in Block Design Application For handling liquid to highly viscous, neutral or aggressive, uncontaminated or abrasive liquids, liquids containing gases or which tend to froth, also containing fibers and solid matter In waste water and waste water treatment engineering, chemical and petrochemical industry, paper and cellulose industry, soap and fats industry, paint and lacquer industry, food and beverage industry, plastics industry, ceramics industry, agriculture, sugar industry and in shipbuilding. Operating Self-priming, single-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 discharge 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. Design features The pump and drive are held together by the bearing bracket to form a modular unit. By means of external casing connecting screws (clamping screws), the discharge casing, stator and suction casing are interconnected. The suction casings are designed particularly favorable to flow. The pump sizes 0 to 550 are supplied in cast iron and are provided with staggered holes for cleaning. The stator vulcanized into a tube is provided with external collars vulcanized to it on both sides, reliably sealing towards the suction casing and discharge casing and protecting the stator shell from corrosion. 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 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 of particularly simple and sturdy design and easily absorb the eccentric movement 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. 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 construction system and, in case of conversion to a different mechanical seal design, can be easily combined with one another. Installation spaces for mechanical seals according to DIN EN 75 (except for double mechanical seal). For further information refer to pages, 5, and 7. Technical data Deliveries, admissible speed ranges and required drive powers are to be taken from the performance graph on page and/or the separate individual characteristic curves.

For further data, refer to pages and 5. GB/207.0 Ident-No. 229

2 Bearings The driving and the joint shaft are situated in the reinforced bearings of the electric motors, gear motors or control gear which also absorb the generated axial forces. As all drives are only supplied with reinforced bearings it must be assured that the assigned pumps can be run at full capacity within their permissible application limits. Drive The drive can be provided by non-explosion-proof or explosionproof three-phase motors, gear motors or control gear. For drive options see page 0. For technical data and dimensions, please refer to the separate sales documentation, data sheet A considerable advantage is the fact that within a pump size the connection dimensions for all drive types are the same. This allows a later change to a different drive type or size. Installation AEB pumps may be installed horizontally or vertically, depending on the shaft seal. In case of vertical arrangement, shaft shank downwards is not admissible. Exchangeability of components The components of all eccentric screw pumps are of a modular design. This allows a simple and cost-effective spare parts management even if different series and designs of pumps are used. 2 GB/207.0 Ident-No. 229
