Integrated (internal) product recirculation from pump discharge to seal chamber.
1. Minimizes risk of freezing / polymerizing of fluid in flush piping plans exposed to atmosphere.
2. Removes heat from the seal chamber as well as acting as a vent connection in horizontal pumps.
1. Recommended in clean fluids.
2. Recommended for fluids which thicken at ambient temperature.
1. Ensure that the recirculation is sufficient for seal heat removal.
