It is usually combined with cleaning of the wet end and inspection of the impeller and diffuser.<\/p>\n<ul>\n<li>Switch off and isolate the pump electrically, then close valves and drain the housing.<\/li>\n<li>Separate the wet end from the motor, remove the impeller and access the mechanical seal and housing joint.<\/li>\n<li>Replace the mechanical seal following the Pentair procedure, avoiding any contact with the polished faces.<\/li>\n<li>Fit the new housing and diffuser o-rings, ensuring they are clean, correctly seated and not twisted.<\/li>\n<li>Install the new lid o-ring in the cover groove and clean the sealing surface on the housing.<\/li>\n<li>Reassemble the pump, reconnect pipework, prime the wet end and check carefully for any signs of leakage.<\/li>\n<\/ul>\n<p>Using a thin film of silicone based lubricant that is compatible with pool elastomers can make assembly easier and help extend the life of the<br \/>\nnew o-rings.<\/p>\n<h3>Good practice for long seal life<\/h3>\n<p>With the Pentair Superflo seal and o-ring kit P-SFL-OSET correctly installed, a few simple habits will help the new seals deliver many seasons of<br \/>\nreliable service.<\/p>\n<ul>\n<li>Maintain balanced water chemistry to reduce chemical stress on rubber components.<\/li>\n<li>Avoid running the pump dry, which can overheat and damage the mechanical seal.<\/li>\n<li>Inspect the lid area and housing joint periodically for early signs of damp or deposits.<\/li>\n<li>Plan a full seal replacement at regular intervals on intensively used installations.<\/li>\n<\/ul>\n<p>A complete gasket renewal with the Pentair Superflo seal and o-ring kit P-SFL-OSET restores the main sealing points in the pump wet end and<br \/>\nhelps keep the filtration system efficient, quiet and well protected.<\/p>","protected":false},"excerpt":{"rendered":"<p>Pentair Superflo seal and o-ring kit P-SFL-OSET The Pentair Superflo seal and o-ring kit P-SFL-OSET is a complete gasket set for restoring the main hydraulic seals in Superflo pool pumps.
