Davey – StarFlo VS Complete Motor Assembly (No VSD) for DSF420VSCE

This is the genuine Davey replacement complete motor assembly for the StarFlo VS DSF420VSCE variable-speed pool pump. Rated at 2.2 hp / 1,650 W, it supplies the mechanical drive at the heart of the pump without including the Variable Speed Drive (VSD) electronics — making it the correct service part when the motor itself has failed but the VSD unit remains serviceable. Restoring the motor to factory specification brings the pump back to full filtration performance quickly and cost-effectively.

Compatibility

This motor assembly is designed exclusively for the Davey StarFlo VS DSF420VSCE — the 2.2 hp, 1,650 W model in the European StarFlo VS range. It is not interchangeable with the smaller DSF250VSCE (1.2 hp / 900 W) or with non-VS StarFlo variants. Always confirm your pump’s model label before ordering. The DSF420VSCE is suited to in-ground and above-ground pools up to 104,000 litres and is also used in large swim spas, plunge pools, and solar pool heating circuits.

Why Genuine Matters

As an OEM Davey spare part, this motor is engineered to exact factory tolerances and pairs correctly with the DSF420VSCE’s existing VSD, impeller, and mechanical seal. Aftermarket alternatives risk mismatched shaft dimensions, incorrect winding specifications, or incompatibility with the pump’s digital control board — potentially causing premature failure or voiding your Davey warranty. A genuine replacement also ensures the pump’s 316 stainless steel shaft interface and silicon carbide / Viton mechanical seal seat are correctly matched from day one.

Installation

Motor replacement on a variable-speed pool pump involves working with mains electrical connections and the pump’s VSD wiring harness. Installation should be carried out by a qualified pool technician or licensed electrician. Ensure the pump is fully isolated from power before beginning work, and consult the official Davey StarFlo VS Installation and Operational Instructions for torque values and reassembly sequence.
