Davey - Silensor / SilensorPro Service Motor with Splined Shaft 75 mm Three-Phase (New Generation) - S75SMF3

Davey – Silensor / SilensorPro Service Motor with Splined Shaft 75 mm Three-Phase (New Generation)

This is a genuine Davey replacement service motor for three-phase Silensor and SilensorPro pool pumps. Featuring a splined-groove shaft interface (new-generation design), it directly replaces the complete motor assembly on models SLL1503F, SLL2003F, and SLL3003F when the original motor fails due to bearing wear, winding failure, or end-of-service-life deterioration.

Compatibility

Designed exclusively for the Davey Silensor and SilensorPro three-phase pump range: SLL1503F, SLL2003F, and SLL3003F. The 75 mm motor body diameter and splined shaft groove match the new-generation hydraulic end on these models. It is not suitable for single-phase Silensor variants, the larger SLL4003F, or older keyed-shaft pump generations — always verify your pump’s model number and shaft type before ordering.

Why Genuine Matters

Using a genuine Davey service motor ensures the correct 400 V three-phase winding configuration, IP56 enclosure rating, and Class F insulation are maintained — all critical for safe, warranty-compliant operation. The splined shaft interface is precision-matched to the Davey Silensor impeller hub, eliminating the slip and vibration risks associated with non-OEM alternatives. Davey’s factory quality control means the motor leaves the box tested and ready to reinstall.

Installation

Motor replacement must be carried out by a qualified electrician and a competent pool technician. Three-phase wiring must comply with local electrical authority specifications, and rotation direction (clockwise when viewed from the wiring-connection end) must be confirmed before finalising installation. A contactor with quick-trip overloads rated to the correct amperage is required. Refer to the official Davey Silensor servicing instructions for full disassembly and reassembly procedures.
