APV SPX L808581 Double Seal Kit EPDM W55 35 SIC

APV SPX L808581 Double Seal Kit EPDM W+55/35 SIC is a replacement set for SPX FLOW APV W+ centrifugal pumps, specifically the W+55/35 variant. The kit provides a complete double shaft-seal replacement configured with EPDM elastomer O-rings and silicon carbide (SiC) seal faces to seal the pump shaft against process liquids. Listed in SPX FLOW spare-parts catalogs for W+ pumps, it is intended to restore sealing integrity after wear or failure and to minimize leakage and downtime. The standard W+ configurations commonly use SiC seal faces with EPDM O-rings, though exact face pairing can vary by kit variant (SiC/SiC or SiC/Carbon with EPDM components). This kit is designed to fit SPX FLOW APV W+ series pump assemblies and replaces worn mechanical seals to maintain pump performance in typical industrial fluid-handling applications.
