Replacement Impeller for STP-3000-T & STP3000SS-T Counter-Current Systems (Part 21) - 7017379

Bosta – Replacement Impeller for STP-3000-T & STP3000SS-T Counter-Current Systems (Part 21)

This is the genuine Bosta replacement impeller (part 21) designed specifically for the STP-3000-T and STP3000SS-T counter-current pool systems. The impeller is the rotating hydraulic core of the pump unit, responsible for drawing in and accelerating water to generate the powerful swimming current. Replacing a worn or damaged impeller restores full flow performance and protects the motor from overload.

Compatibility

This impeller fits the Bosta STP-3000-T and STP3000SS-T counter-current systems — the 3 kW, 400 V AC (three-phase) wall-mounted pool jet units. The STP3000SS-T is the stainless-steel variant of the same platform. Always verify your system’s part diagram (position 21) before ordering to ensure correct fitment.

Why Genuine Matters

A genuine Bosta impeller is precision-matched to the pump housing and motor shaft of the STP-3000 series, ensuring correct clearances, balanced rotation, and the full rated flow of up to 80 m³/h. Non-genuine alternatives risk vibration, premature wear, and reduced current output — undermining the training performance the system was designed to deliver.

Installation

Impeller replacement requires draining and isolating the counter-current unit, disassembling the pump body, and correctly re-torquing the impeller onto the motor shaft. Installation by a qualified pool technician is strongly recommended to ensure safe reassembly and avoid voiding any system warranty.
