Answer:Two dual-spring high-pressure seals with the specified 0.045-gland design.
Answer:The ACQUITY I-Class Binary Solvent Manager pump-head configuration.
Answer:Do not assume interchangeability. The dual-spring and flanged seal designs are selected for different pump-head geometries.
The Waters dual-spring high-pressure pump seals are replacement components for specified ACQUITY I-Class Binary Solvent Manager pump heads. Their dual-spring construction and 0.045-gland designation distinguish them from ordinary flanged UP30 seals and other ACQUITY pump seal styles. Two seals are supplied in this service pack. The high-pressure seals help maintain mobile-phase containment during the pump stroke and support reproducible solvent delivery when installed with sound plungers and correctly maintained check valves. Selection depends on the actual pump-head design; this seal should not be assumed to fit every ACQUITY or Alliance pump. When servicing the pump, depressurize the fluid path, inspect the plungers and mating surfaces, install the correct seal orientation and complete leak and pressure-performance checks after priming.
