Eccentric screw pumps of the block type Series ADBP

1 ALLWEILERaALLWEILERaMaterial pairing and type are adapted to suit the resepctiveoperating conditions. For further details see page bearing of the driving/stub shaft is in reinforced bearings ofthe electric motors or variable speed gears which, at the sametime, absorb the axial forces all drive units are only supplied with reinforced bearing, it isensured that the allocated pumps can always be fully opera-ted within their admissible application the drive, non-explosion-proof and explosion-proof electricmotors or variable-speed gears can be provided (in specialcases, drive is also possible by geared motors, please inquire).For driving possibilities, see page 6. For technical data anddimensions, please refer to the separate sales document,sheets 19-52-0000-008-4 and pumps can be installed horizontally or vertically.

4 Positive displacement pump whose pump-ing elements are formed by the rotating Eccentric screw (rotor)and the fixed stator. In any cross-sectional plane, these two ele-ments are in contact with each other at two points which formtwo sealing lines over the length of the pumping elements. Thematerial contained in the sealed enclosed cavities which areformed as the rotor turns is displaced axially and with completecontinuity from the suction to the delivery end of the the fact that the rotor rotates, no turbulence is produ-ced. The constant volume of the enclosed cavities excludessqueezing thus guaranteeing an extremely gentle low-surgepumping designThe suction casing, shaft seal and coupling rod are identical forall three on the size, the stator is screwed directly into thesuction casing or via a reducing using/omitting the reducing ring (between suction casingand stator) and by changing the rotor and stator, the basicpump can easily be converted to a different size, while retainingthe above-mentioned components/sub-assemblies of the pumps are basically of a three-stage design.

5 Extremelyhigh metering accuracy is obtained due to the long sealing linebetween the rotor and suction casing with integrally cast lantern and integral sealhousing is bolted directly to the drive torque from the drive unit is transmitted via a stub shaftand a coupling rod to the rotor. The coupling rod terminates atboth ends in encapsulated universal joints which are of a parti-cularly simple rugged design able to withstand the eccentricmovement of the rotor without any sealBy uncooled stuffing box or by uncooled, maintenance-freenon-balanced single-acting mechanical request, shaft seal rings can be used for shaft sealing (spe-cial design).2 Type codingCodes for materialDesignPump typePosition in type coding1234567890 ADBP 0,4.
