Tab 04 Specifications.pdf

This document is a specifications sheet for PHPK Spare Parts & Rebuilds, detailing specific replacement parts for CVI cryopump equipment. The specification strictly prohibits substitutions or alternative parts from other vendors, indicating these are precise, specialized components. The required items include 4 compressor adsorbers (part number 37-2550-08725), 2 CBST 6.0 helium compressor rebuilds, 5 CGR511 LS2 drive head rebuilds, multiple helium hose rebuilds in 10 and 20-foot lengths, 2 compressor hour meters, 1 MP5000 CGR511 1st stage displacer (rebuilt), 1 CGR511 LS2 2nd stage displacer (new, complete), and 2 GN2 vent valve rebuilds.

The specification is part of a NASA/NSSC solicitation (Number 80NSSC900890Q) for spare parts and components for CVI Cryopump Rebuild. The document emphasizes the critical nature of these replacement parts by explicitly stating that no alternative parts or vendor work will be permitted, suggesting these components are mission-critical and require exact specifications to maintain equipment functionality.
