Dayuan Mechanical Seals

The 35mm Type 192 mechanical seal is a DIN 24960 elastomer-bellows seal with silicon carbide faces on both sides and a Viton (FKM) elastomer, cross-referenced to US Seal VGM-8255Z. It is the 35mm seal for the Dayuan KLDS155 vertical multistage centrifugal pump, and the same seal serves the 35mm position on Travaini liquid ring vacuum pumps. Built to OEM-equivalent standards or higher.
