LPS-291
LPS-291 series is Thermosyphon System basically used as a storage & pressurizing unit. Thermosyphon used for double mechanical seals in back to back or tandem seal arrangements. Thermosyphon provide necessary lubrication and cooling to the seal faces to increases the life of the seal. It’s contains cooling coil to bring down the temperature of barrier fluid coming from seal to thermosyphon.
