John Crane Type21 Replacement SIC/SIC/VITON 40 Mm Mechanical seal in the TG560 series is the ideal for general-purpose applications,designed for large batch production. Efficient stock keeping due to easily interchangeable parts.Type 560 series is widely used in the Centrifugal pumps, turbine pumps, compressors, hot water pumps and other rotary shaft equipment. Features Single and ealstomer bellows mechanical seal Bi-directional Non-sliding design structure,elastomer bellows automatically compensates for primary ring wear. TG560B,TG560K,TG560C,TG560A show difference in the dimensional data, avaliable with different standard working lengths. Vailable in metric and inch sizes 560 series can also be used as double face mechanical seals in two sets arrangement Recommended Applications Water and waste water technology Process pumps Industrial pumps Petroleum chemical industry Other Rotating Equipment Operating range Shaft diameter: d1=8...80mm(0.375'' ...3.000'') Pressure: p=0...1.0Mpa（145psi） Temperature: t = -20 °C ...150 °C(-4°F to 302°F) Sliding velocity: Vg≤13m/s（42.6ft/m） Notes: The range of preesure,temperature and sliding velocity is depend on seals combination materials
