Type 1677 mechanical seals, equivalent to Vulcan 1677, suit food/chemical pumps (dairy, beer, pharmaceuticals). As active-driven wave spring seals with peak-to-peak spring technology, they offer 

excellent axial movement capability, are radially compressed tightly, and comply with EN12756. 

Compatible with various high-quality materials and elastomers as standard. Features: Competitive 

pricing with diverse material combinations and superior design; One-piece construction with peak-to-

peak springs eliminates corrosion at welds (avoiding common failure modes); High-energy rotating 

ring reduces shaft fretting wear for reliable sealing.

     Seal Face Materials:Rotating: Silicon Carbide              Pressure:10 bar(145 psi)Dynamic; 15 bar(217
