DescriptionProduct recirculation from discharge through a
cyclone separator and a heat exchanger to seal chamber.
Features1. Improves pressure margin to vapor pressure.2.
Improves temperature margin to meet secondary sealing element
limits, to reduce coking or
polymerizing & to improve lubricity.3. Removes entrained
solids from the process fluid.4. Particles from cyclone separator
are returned to suction.
Use1. In hot services containing suspended solids.
Caution1. Pump throat bushing is recommended.2. Ensure use for
services containing solids with specific gravity twice or more than
that of process fluid.3. Cooler duty is high leading to fouling on
waterside.
