Davey - Starflo Pump Filter Basket O-Ring - 403131SP

Davey – Starflo Pump Filter Basket O-Ring (403131SP)

This is the genuine Davey replacement O-ring that seals the filter basket cover on the Starflo DSF series pool pump. It creates a watertight seal between the filter basket and its cover, preventing air ingestion and water leaks at the pump head. Replace it whenever you notice air bubbles returning to the pool, difficulty priming, or visible deterioration of the existing seal.

Compatibilidad

This O-ring (Davey item 8 in the official Starflo spares diagram) fits the complete Starflo DSF single-phase range — DSF150, DSF200, DSF250, DSF300 and DSF420 — including all CE variants designed for the European market, as well as the three-phase DSF3003FCE and DSF4203FCE models. Always cross-reference your pump model and this Davey part number 403131SP before ordering.

Por qué lo genuino importa

A correctly sized, genuine Davey O-ring ensures a precise fit against the filter basket cover and casing, maintaining the suction integrity that keeps your pump primed and running efficiently. Ill-fitting aftermarket seals can allow air to enter the suction line, causing loss of prime, reduced flow, and potential pump damage. Genuine parts also help protect your Davey warranty.

Instalación

Remove the filter basket cover and lift out the old O-ring. Clean the seating groove thoroughly before fitting the new O-ring. A light application of Hydra Slip or a suitable silicone-based lubricant on the O-ring and thread will aid installation and extend seal life. Firm hand-tightening of the cover is all that is required — do not over-tighten.
