Flowserve-Durametallic-Accessories - SLD

Accessories - SLD

BRAND: Durametallic

The SLD seal support system from Flowserve dispenses lubrication to the atmospheric side of mechanical seals. It is ideal for seals subjected to periods of dry running or cavitation when product liquid (pumpage) does not provide adequate film between seal faces. The SLD is proven to greatly extend flushless seal life in harsh slurry conditions.
