9、tion and maintenance. It is therefore essential that this operating manual is read prior to installation and commissioning by the fitters and the responsible technicians/ operators, and must always be available at the operating location of the machine.1.1.UseThe 51 - 550 series gear pumps described

10、in these operating manual, henceforth called Feed pumps“ or Pumps“, are only suitable for conveying lubricating liquids that do not have a cor-rosive effect on the pump materials used (Section 1.3. Any liquid to be pumped is hereinafter referred to simply as the “me-dium”.If you require further info

Areas of responsibility, competencies and monitoring of th

20、e staff must be pre-cisely regulated by the operator. If the personnel do not have the necessary knowledge, they must be trained and instructed accordingly. This can be implemented, if necessary, by the manufacturer / sup-plier on behalf of the machine operator. In addition, the operator must ensure

21、 that the content of this operating manual is fully understood by the personnel.2.3.Dangers from non-compliance with safety instructionsNon-compliance with safety instructions can pose a danger not just to personnel, but also to the envi-ronment and machinery. Non-compliance with the safety instruct

31、IN EN 13463-5, Section 4.6.3,Appendix B, is not required as the lubricant cannot be topped up. The seals are constantly lubricatedby the medium. Dry running must be avoided (see Section 6.2.The outer radial shaft sealing ring (as shown in Figure 4.7 only transfers 5W into the pump shaft inextreme ca
