Davey - Priming Plug with O-Ring (Silensor / SilensorPro) - 8890-2SP

Davey – Priming Plug with O-Ring (Silensor / SilensorPro)

The 8890-2SP is a genuine Davey replacement priming plug and O-ring kit designed for the Silensor and SilensorPro variable speed pool pump ranges. The plug seals the priming port on the pump casing, and its integrated O-ring ensures a watertight, air-free seal essential for correct priming and efficient pump operation. Replace this part whenever the plug is lost, cracked, or the O-ring has deteriorated and is causing air ingestion or leaks.

Compatibilité

This part fits the full Davey Silensor (SLL series) and SilensorPro pump families, including the SP200BT, SP200BTP, PM200SV/BT, PM400PV/BT, and SP400PV/BT models. It is listed as item 1 in the official Davey SilensorPro BT spare parts diagram, with one plug and O-ring required per pump. Always verify your pump model number before ordering.

Pourquoi l'authenticité est importante

Using a genuine Davey priming plug and O-ring guarantees correct dimensional fit and material compatibility with the pump casing. An ill-fitting aftermarket plug can introduce air leaks that cause loss of prime, reduce flow, and may trigger the pump’s loss-of-prime protection — leading to unnecessary downtime. Genuine parts protect your warranty and the longevity of your pump.

Installation

The priming plug is a simple hand-tightened component. Before fitting, inspect the port threads on the casing for damage and ensure the seating surface is clean. Insert the new O-ring into position, then thread the plug in by hand until snug — do not overtighten. After refitting, re-prime the pump and check for leaks before returning to normal operation.
