Wirnik do systemu przeciwprądowego STP-2200 i STP-2200SS (część 21) – 7017377

Bosta – Impeller for Counter Current System STP-2200 & STP-2200SS (Part 21)

This is the genuine Bosta replacement impeller (Part No. 21) for the STP-2200 and STP-2200SS counter current swim jet systems. The impeller is the rotating hydraulic component at the heart of the pump, responsible for generating the powerful, adjustable water flow that drives the counterflow jet. Replacing a worn or damaged impeller restores the system’s full 55 m³/h flow performance.

Kompatybilność

This impeller is designed exclusively for the Bosta STP-2200 (230 VAC) and STP-2200SS (230 VAC) counter current systems — both the standard and stainless steel variants of the 2.2 kW, 75 mm connection model. It is not interchangeable with other STP models such as the STP-3000 or STP-4000. Always verify your system’s model designation before ordering.

Dlaczego oryginalność ma znaczenie

A genuine Bosta OEM impeller ensures the correct hydraulic profile, material grade, and dimensional tolerances for your STP-2200 system. Off-brand alternatives may reduce flow output, increase motor load, or cause premature wear. Using an authentic part also helps maintain any applicable warranty on your counter current unit.

Instalacja

The impeller is an internal wet-end component requiring the pump to be isolated from the power supply and drained before replacement. Installation involves disassembling the pump casing to access the motor shaft. Professional installation by a qualified pool technician is strongly recommended to ensure correct torque, shaft alignment, and safe reassembly.
