Davey - SilensorPro SP400BT Replacement Service Motor - SP87VSM-1

Davey – SilensorPro SP400BT Replacement Service Motor

This is the genuine Davey service motor (part SP87VSM-1) for the SilensorPro SP400BT variable-speed pool pump — a direct OEM replacement for the pump’s core drive unit. It is the correct service part to specify when the existing motor has failed, is drawing excess current, or has developed bearing noise, overheating, or speed-control faults beyond component-level repair.

Compatibility

This service motor is confirmed as the factory-specified replacement for the Davey SilensorPro SP400BT (and PM400BT) pump. The SP400BT is Davey’s larger-capacity Bluetooth-enabled variable-speed pool pump, operating across a speed range of 1,050–3,100 rpm and a power envelope of 125 W to 1,557 W. Always verify your pump’s model label and Davey part number before ordering; this motor is not interchangeable with other Silensor or SilensorPro variants.

Why Genuine Matters

The SP400BT motor uses Davey’s patented water-cooled technology, which is integral to the pump’s whisper-quiet operation and energy efficiency. A genuine Davey replacement ensures the correct winding specification, IP45 enclosure sealing, and Class F motor insulation are preserved — maintaining both performance and safety compliance. Third-party alternatives risk voiding your warranty and compromising the pump’s variable-speed inverter drive.

Installation

Service motor replacement is a workshop-level task requiring electrical disconnection, draining of the pump, and precise re-assembly torque to maintain the IP45 seal. Davey recommends this work is carried out by an authorised Davey service agent or qualified pool technician. Ensure power is fully isolated and the pump is depressurised before beginning any service work.
