Davey – Rear Casing O-Ring for Silensor SLS & SLL Pool Pumps

This is the genuine Davey replacement O-ring for the rear casing of Silensor SLS and SLL series pool pumps, including SilensorPro models. It forms a critical watertight seal at the rear of the pump body, preventing water ingress and leaks during operation. This seal is typically inspected or replaced whenever the pump casing is opened for servicing — for example, during bearing changes, mechanical seal replacement, or motor removal.

Compatibilitate

This O-ring fits the full Davey Silensor SLS and SLL pump ranges, covering single-phase and three-phase variants across all output sizes (SLS100, SLS150, SLS200, SLS300, SLL150, SLL200, SLL300, SLL400 and their CE-suffix European variants), as well as SilensorPro models. Always verify your pump’s model number before ordering.

De ce autenticitatea contează

Davey engineers the Silensor’s water-cooled motor casing to precise tolerances, so correct O-ring dimensions are essential for a leak-free seal and long service life. A genuine Davey part guarantees the exact material grade and profile to withstand pool water chemistry and temperature. Using non-genuine substitutes risks premature seal failure, water ingress into the motor casing, and potential pump damage.

Instalare

Replacement of the rear casing O-ring requires disassembly of the pump using the Davey Silensor service spanners (part numbers 13810SP and 13810-1SP). The O-ring should be seated cleanly in its groove before reassembling the casing nut. It is recommended that a qualified pool technician or authorised Davey service centre carries out the work to ensure correct reassembly and to preserve the pump warranty.
