Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L) 93/140
NOTE
The pump’s component parts are modular and therefore fully interchangeable.
Whenever parts have to replaced, please specify in the order:
Pump type
Serial number (marked on pump identification plate).
Reference number on the detailed diagram, name and part number as
indicated on the spare parts and accessories list (section SPARE PARTS
LIST of this manual).
To simplify maintenance work, two kits have been devised.
The Gaskets
Kit, containing all the gaskets recommended for substitution after
disassembly of the pump and the most commonly used removable parts.
You are advised to keep this kit in a dry room, away from heat and light (sun and
UV rays) in order to prevent hardening of the elastomer parts.
The Maintenance
Kit, including, as well as the Gaskets Kit, the 1st and 2nd
stage vanes and other parts that it may be necessary to replace when
overhauling the pump completely. These parts have a life of approx. two years
under conditions of normal operation.
