Trading and engineering company focusing on process pumps
Allweiler has just launched their brand new dosing pump, AEB-DE.
During the development of the new pump, work has been done to combine Allweiler's extensive experience with new market requirements and customer needs.
The AEB-DE pump is available in a compact block design in four different sizes (1.3, 2.3, 5.3 and 12.2). However, a base plate can be added as an option. The connections to the pump can be chosen in either a threaded or flanged version.
To achieve broad market coverage, the pump housing will be made of high-quality stainless steel. This choice of material makes it possible to use the pumps in a wide range of applications. As standard, the suction casing has three additional closed bore connections to ensure flexible use of the pump. The suction casing can be rotated 90° while still allowing the pump to drain safely. In addition, these bore connections can be used to add sensors, flush or fill the pump
Another improvement is the location of the mechanical shaft seal, which now comes as standard. The shaft seal is located within the fluid flow, ensuring that it is permanently flushed and cooled. This makes it possible to install the new AEB-DE both horizontally and vertically without any risk of dry-running the mechanical shaft seal. If necessary, a flush can be offered as an option for the shaft seal or alternatively the pump can be equipped with an old-fashioned stuffing box.
To ensure safe pump operation, the new dosing pumps can be upgraded with a dry run protection (ATLS-T1) or a pressure sensor (ATLS-P).
The conceptual design phase has been approached with an innovative approach. The new series has only four different sizes, replacing the six sizes of ADP/ADBP and ANP/ANBP that will be phased out. With their optimized geometries, the new pump can handle the same range of operating data without any limitation.
Another advantage of AEB-DE is that all four sizes have identical installation dimensions. The only difference is a variation of the conveying elements (Rotor & Stator) and the use of adapters inside the pump. This flexibility allows for a variation in flow rate by simply replacing the transport elements without requiring costly renovations and installation adjustments such as pipe changes etc.
The following pump documentation is created:
For new customers and new RFQs, the new pump must be selected.
From April 1, 2020, only AEB-DE will be offered to give existing customers enough time to switch from the outdated to the new series.
With the introduction of this new pump, the old ADB/ADBP and ANP/ANBP series will be phased out. They will only be available as replacement pumps until December 31, 2020. Spare parts will be available without any restriction.
Although two different series have been consolidated into one new pump, the same range of flow rates can be handled. In addition, the application fields are expanded, creating incremental customer benefits (e.g. vertical installation, identical installation space for different sizes).
Based on technical improvements and changes to the joints and sealing, it was not possible to achieve dimensional interchangeability.
