Impeller for Counter Current System STP-2200-T & STP-2200SS (400VAC) - 7017378

Bosta – Impeller for Counter Current System STP-2200-T & STP-2200SS (400VAC)

This is the genuine Bosta replacement impeller (part No. 21) designed specifically for the STP-2200-T and STP-2200SS counter current systems running on 400VAC three-phase power. The impeller is the core rotating component of the pump, responsible for generating the high-volume water flow that creates the adjustable swimming current. Replacing a worn or damaged impeller restores the system’s full hydraulic performance of up to 55 m³/h.

Kompatibilität

This impeller fits the Bosta STP-2200-T and STP-2200SS counter current pump units operating at 400VAC (three-phase). It is not compatible with the 230VAC single-phase variants of the STP-2200 range. Always verify your system’s voltage rating and part diagram reference (No. 21) before ordering.

Warum Echtheit zählt

Genuine Bosta spare parts are manufactured to the exact tolerances required for the STP counter current pump housing and motor shaft. An OEM-spec impeller ensures correct hydraulic balance, minimises vibration, and protects the motor bearings — safeguarding the longevity of a system rated at 2.2 kW and 55 m³/h maximum flow. Aftermarket alternatives may cause premature wear or reduced jet performance.

Installation

Impeller replacement requires draining and opening the pump wet end, and should be carried out by a qualified pool technician familiar with counter current pump assemblies. Ensure the power supply is fully isolated before disassembly. Refer to the STP-2200 parts diagram (item No. 21) and Bosta service documentation for correct torque settings and reassembly sequence.
