Kennametal SN159-VP 50 mm BAZOOKA™ Venturi Nozzle

The Kennametal SN159-VP 50 mm is a BAZOOKA™ venturi blast nozzle with a wide entry and a wear-resistant BP200 SiAlON liner. The nozzle features a robust polyurethane jacket and a 50 mm aluminium thread. The combination of the 32 mm (1-1/4") wide entry and the extra-wide exit produces a blast pattern that can be up to 60% larger than that of a standard long venturi blast nozzle. This allows large surface areas to be treated more quickly and evenly. The SN159-VP 50 mm is designed for use with a blast hose with an internal diameter of 32 mm (1-1/4"). The nozzle is particularly suitable for large-scale surface preparation of steel structures, ships, tanks and industrial installations. At a nozzle pressure of 8.6 to 10.3 bar (125–150 psi), the BAZOOKA™ geometry provides intensive surface treatment for a thoroughly cleaned finish. At 6.2 to 6.9 bar (90–100 psi), the nozzle is suitable for general blasting work and light sweep blasting of surfaces. The BP200 SiAlON liner provides wear resistance comparable to tungsten carbide when used with standard steel shot, standard steel grit, iron silicate and aluminium silicate. At the same time, the nozzle weighs approximately half as much as a comparable tungsten carbide version and is more resistant to breakage than silicon carbide and standard silicon nitride versions. The nozzle is not recommended for use with hardened steel shot or hardened steel grit. For bore sizes larger than 1/2" or applications using hardened steel abrasives, the T159-VP 50 mm with a tungsten carbide liner is a more suitable alternative.
