Designed for residential swimming pools and compact pool-spa combinations, the Onga WhisperFlo WHFL-750-1P delivers stable everyday circulation with smooth hydraulic performance suited to continuous filtration systems. Its refined hydraulic platform is developed to maintain efficient water turnover while helping minimise operational disturbance around residential installations.
The pump produces flow rates reaching approximately 350 L/Min with maximum head capability of approximately 17 m. Operating from a 230–240V single-phase electrical supply, the 750 W motor configuration supports residential filtration duties, spa circulation systems, and general pool recirculation applications requiring dependable daily operation.
Hydraulic efficiency is supported through Pentair’s FunnelFlo diffuser design working together with a precision impeller arrangement to improve flow transfer while limiting internal resistance. The large-capacity strainer basket assists with debris retention between servicing intervals, and the transparent inspection lid allows quick visual monitoring without removing components.
Long-term durability is supported through the engineered thermoplastic casing developed for chemically treated pool environments and outdoor exposure conditions. The motor assembly incorporates a stainless steel shaft, permanently lubricated sealed bearings, integrated overload protection, and a Cam and Ramp lid system providing simplified quarter-turn access during maintenance servicing.
