The Safeseal Type SB2/Type SB2A is a dual-cartridge seal. Its double-balanced design ensures the reliability and longevity of the seal in the most demanding conditions. The Type SB2/Type SB2A seal is ideal for use with environmentally hazardous and abrasive fluids, most often used in pumps in pulp mills, minerals processing and other slurry duties up to 40% solids by weight and a solids hardness of 8 Mohs. The Type SB2/Type SB2A seal is widely used with other process equipment including agitators.
Upstream Pumping seal face technology
Adding Upstream Pumping seal face technology extends the life of the seal by combating severe-service conditions, including high-heat generation, low-lubricity and intermittent dry running conditions. By eliminating the need for a flush, USP technology nearly eliminates water consumption and decreases power usage.
