Supplementary information for modified versions

(With identity code specification "Version": "M" - "modified")

Technical data of pumps in the modified version can deviate from those of

the standard pumps. They can be queried by stating the details of the

serial number.

During operation with an automatic stroke length adjustment control

together with a variable speed motor, the stroke rate must not fall below

30 strokes / min. Otherwise technical problems occur, because the

mechanical resistance of the stroke adjustment spindle becomes too high.

The motor data sheets for the modified version are valid. They may

deviate from the standard motor data sheets.

With a modified version, it is absolutely necessary to specify the details of

the serial number requesting and ordering the spare and replacement

parts.
