Pump Repairs and Upgrades Standards

(starting with Vertical Turbines, VPRS, rev. 1)

<=== download latest rev


Pump industry is undergoing renewed interest to technical aspects of quality of repairs. Pump users expectations of good quality of repairs must be matched by a well defined set of specifications, to clear state the extend and details of a repair job. The first such specification has been initiated by a working group of the Pump Magazine, with cooperation with Pumps & Systems magazine, and the reviewers are in process of working on the second draft. Users, manufacturers, and repair shop facilities' input is encouraged, to provide inclusive and rounded basis for the final document to serve pumping industry needs in quality repairs and overhauls of pumps.


The original draft was reviewed September by the Pump Magazine Advisory Committee, and a working group has been put together to get the VTP Pump Repair Standard (VPRS) published. Draft (rev. 6) is the current work. For those interested, we can review your interest and background, and include you on board with this working group (see list of the group members at the end of the Editorial).
