4 Parts number designation
4.1 Part numbers of modules
The delivery may include the entire pump product (PUPR.0) and/or pump spare parts. The installation-ready pump
unit is divided into the following modules: pump (PUMP.0), assembly (ASSE.0), drive unit (DRUN.0), measuring
instrumentation (MEIN.0), external degassing system (DESY.0) and documents (DOCU.0).
The pump (PUMP.0) is divided into the following modules: wet end (WEEN.1), sealing unit (SEUN.2) and bearing
unit (BEUN.3). The assembly is divided into the following modules: sealing water equipment (SWEQ.4), coupling unit
(COUN.5) and baseplate (BAPL.6). The drive unit (DRUN.0) is divided into two parts: motor (DRMO) and frequency
converter (FRCO). Documents are divided into two categories: documents supplied with the delivery and documents
supplied separately.
4.2 Part numbers of parts, connections and documents
Parts, which have part numbers consisting of a three/four-digit number plus two digits after a dot. The first digit after
the dot shows the number of the delivery unit or module in question, while the second digit distinguishes parts of the
same type from each other.
In the part number, the first digit after the dot is determined by the module. For instance, o-ring 412.11. If the module
has many parts with the same name, the second digit after the dot distinguishes the parts from each other. For
instance, 412.12 is the second o-ring in the wet end (WEEN.1).
Connections, which have part numbers consisting of the initial letter C, a two-digit number plus two digits after a dot.
The first digit after the dot shows the number of the delivery unit or module in question, while the second digit
distinguishes connections of the same type from each other.
Documents, which have part numbers consisting of the initial letter D, a two-digit number plus two digits after a dot.
The first digit after the dot shows the number of the delivery unit or module in question, while the second digit
distinguishes documents of the same type from each other.
