Davey - Silensor / SilensorPro Pool Pump Front Casing - 13439

Davey – Silensor / SilensorPro Pool Pump Front Casing

This is the genuine Davey replacement front casing (part number 13439) for the Silensor and SilensorPro pool pump series. The front casing forms the hydraulic wet-end housing that encloses the impeller and directs water flow through the pump. It is typically replaced when the original casing shows cracking, impact damage, or thread wear that compromises pump integrity or flow performance.

Compatibility

Part 13439 is listed in the official Davey Silensor spare parts schedule and is compatible with the Silensor SLS and SLL model ranges (including SLS100, SLS200, SLL150, SLL200, SLL400, SLL1503F, SLL2003F, SLL3003F, SLL4003F) as well as SilensorPro models (SP200BT, SP400BT). European CE-variant models are supported. Always verify your pump’s model and serial number against the Davey spare parts diagram before ordering.

Why Genuine Matters

The Davey Silensor features a water-cooled motor design and is built around a rust-proof casing engineered to precise tolerances — the front casing locks into two specific slots on the motor casing and must seat correctly for safe, leak-free operation. Using a genuine Davey part ensures correct fitment, maintains the pump’s waterproof integrity, and preserves any remaining warranty. Note that Davey specialist service tools (part numbers 13810SP and 13810-1SP) are required to remove and refit the casing nuts during servicing.

Installation

During reassembly, the front casing is aligned with the two slots in the motor casing and the casing nut is turned anti-clockwise to lock it in place, then tightened with the large Silensor spanner. Ensure the power lead is correctly routed before securing. Installation should be carried out by a qualified pool technician familiar with the Davey Silensor servicing procedure (service bulletin SP61/1550/1207).
