Larger residential pool installations and demanding filtration systems can integrate the Onga WhisperFlo WHFL-2100-1P where elevated circulation performance and continuous-duty operation are required. The hydraulic platform is developed to maintain strong water movement capability across high-flow pool and spa applications.
Maximum flow performance reaches approximately 570 L/Min with head capability extending to approximately 21 m. Operating from a single-phase 230–240V electrical supply, the pump delivers 2100 W motor output suited to larger residential pools, spa combinations, extended pipe runs, and in-floor cleaning systems requiring higher hydraulic capacity.
The wet-end assembly combines Pentair’s FunnelFlo diffuser with a high-efficiency impeller arrangement developed to optimise circulation performance while maintaining controlled hydraulic behaviour under demanding operating conditions. Debris management is assisted through the oversized basket configuration, while the clear lid improves servicing visibility during maintenance procedures.
Structural durability is supported through the corrosion-resistant thermoplastic casing together with a commercial-grade motor frame engineered for long-term outdoor operation. The pump also incorporates a stainless steel shaft, permanently lubricated sealed bearings, automatic overload protection, and a quarter-turn Cam and Ramp lid mechanism for simplified basket access.
