The 202UU Series is a robust, single-spring mechanical seal engineered specifically for the demanding environments of submersible motors and water-alkali pumping systems. Known for its compact axial profile and high reliability, the 202UU is the industry standard for preventing fluid ingress in submersible sewage pumps, fountain pumps, and chemical transfer units handling alkaline solutions.
In submersible applications, the 202UU often functions as the primary barrier within the oil chamber, where it must withstand both the external pressure of the pumped media and the internal lubrication requirements of the motor. For alkali services, our 202UU units utilize specialized material pairings that resist caustic embrittlement, ensuring a leak-free operation in high-pH environments.
