The new Wilo-Flumen OPTI series is a direct drive submersible mixer series with 8” to 15.5” diameter propellers optimized for efficiency and durability and a max rated speed range from 1110 to 1690 rpm. The series features three-blade cast stainless steel propellers (58.5–290 lbf thrust range) with the same hydraulically efficient backswept profile as found on Wilo’s medium speed planetary gear reduced mixer series.
Each propeller blade has a hydrofoil profile which achieves thrust-power ratios according to ISO 21630. Propeller clogging is minimized through CFD-based design and extensive testing. Single and double row ball bearings support the stainless steel shaft. A moisture sensing electrode located in the seal chamber and auto-reset winding thermal sensors are standard equipment on all models. With easy maintenance due to the mixer’s modular design and the flexibility of installations, the Flumen OPTI series is Wilo’s high-quality answer to applications in the range of direct drive mixers.
