Pentair – UltraFlow Plus-Dichtungssatz für Pumpe (Positionen 3-5-8-11-13-16) – P-UFL-OSET

Pentair UltraFlow Plus gasket kit for pump (positions 3-5-8-11-13-16)

This is the complete OEM gasket and O-ring service kit for the Pentair UltraFlow Plus pool pump, covering six sealing positions (3, 5, 8, 11, 13, and 16) as identified on the pump’s exploded-view diagram. It bundles every gasket and O-ring you need for a full wet-end reseal in a single part number, so you don’t source individual seals across multiple orders.

What this gasket kit does in the UltraFlow Plus

Each position in the kit seals a specific interface inside or around the pump’s wet end — from the pre-filter lid and drain plugs through to the volute-to-body junction and seal plate. When any one of these seals degrades, the pump loses prime, draws air, or weeps water externally. Replacing all six positions simultaneously ensures no residual worn seal re-introduces a leak after you’ve closed the pump back up.

Für welche UltraFlow Plus-Modelle ist es geeignet?

The kit is designed for the Pentair UltraFlow Plus pump family, which spans 0.75 kW to 2.2 kW in both single-phase and three-phase configurations. Confirm your pump’s exact model and power rating before ordering — the UltraFlow (original) and UltraFlow Plus share a similar chassis but are distinct product lines.

Anzeichen dafür, dass es ausgetauscht werden muss

Visible water weeping around the pre-filter lid, drain plugs, or the volute-to-body joint is the clearest indicator. You may also notice the pump hunting for prime at start-up, or air bubbles returning through the pool return jets — both point to a failed gasket drawing air into the wet end under suction. Any time you pull the motor for bearing replacement, renew this kit at the same time: disturbing the wet end disturbs every seal.

So installieren Sie es

Switch off and isolate power, close suction and return valves, then drain the pre-filter body. Disassemble the wet end sequentially, noting each seal’s position against the diagram. Remove old seals, clean the grooves of any residue, and seat each new gasket or O-ring with a thin coat of silicone-based lubricant — never petroleum-based products, which attack EPDM and Buna-N rubber. Reassemble in reverse, refill, and check for leaks before returning to normal operation.

Warum Originalprodukte von Pentair wichtig sind

OEM seals are manufactured to Pentair’s material and dimensional specification, which means correct cross-section, durometer, and chemical resistance for continuous exposure to chlorinated, salt, and ozone-treated water. Aftermarket kits vary in rubber compound and dimension tolerance; an undersized O-ring seats loosely and fails within a single season.
