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 m\u00b3\/h.<\/p>\n
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.<\/p>\n
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 \u2014 safeguarding the longevity of a system rated at 2.2 kW and 55 m\u00b3\/h maximum flow. Aftermarket alternatives may cause premature wear or reduced jet performance.<\/p>\n
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.<\/p>","protected":false},"excerpt":{"rendered":"
