Pentair - IntelliFlo3® VSF variable speed pool pump 1.5HP 50/63mm - 7035820

Pentair – IntelliFlo3® VSF variable speed pool pump 1.5HP 50/63mm

Delivering up to 24 m³/h at a whisper-quiet variable speed range of 400–4,000 RPM, the Pentair IntelliFlo3® VSF is a 1.5 HP, 230 VAC pump fitted with 50/63 mm glue-socket connections for straightforward integration into European in-ground pool systems. Its patented sensorless flow technology continuously adjusts motor speed to match real hydraulic demand, making it one of the most energy-aware circulation pumps available today. At 5.9 A maximum draw, running costs are kept firmly in check even on larger installations.

Sensorless flow control & energy performance

Unlike conventional variable-speed pumps that simply step through pre-set RPM programmes, the IntelliFlo3® uses proprietary sensorless flow technology to detect changes in system resistance — such as a progressively loaded filter — and automatically compensates to maintain target flow. This self-regulating behaviour, combined with the wide 400–4,000 RPM operating window, can reduce energy consumption by up to 90% compared with single-speed equivalents running at full speed around the clock.

Wi-Fi connectivity & optional automation

Built-in Wi-Fi and Bluetooth® allow the pump to pair with the Pentair Pool and Pro apps, giving pool owners and service professionals remote monitoring and schedule management from any device. An optional relay board expands the IntelliFlo3® into an entry-level automation hub, enabling control of up to two additional pool devices — such as a salt chlorinator or lighting circuit — without a separate automation controller. An optional touchscreen panel is also available for on-site operation.

Hydraulic connections & installation

The 50/63 mm glue-socket ports suit the pipe sizes most commonly found in European pool plant rooms, and the compact footprint (longest dimension 633 mm) keeps the pump compatible with tight equipment enclosures. At 20.4 kg the unit requires two persons or mechanical assistance for positioning, and professional installation is strongly recommended both for plumbing integrity and to support any applicable warranty registration.
