▶1.5 times higher flow rate than stock
The flow rate is 56% higher than that of the stock product due to the larger diameter of the impeller and the larger area of the blades made possible by the special housing.
※Impeller outer diameter: STD φ64 → Gr.A φ73, flow rate: STD 160 ℓ/min → Gr.A 250 ℓ/min
※Radiator capacity needs to be increased.
▶High durability and high rigidity
The outer diameter of the bearing has been increased from φ30 (BNR32 STD) to φ35, which is superior in terms of durability and rigidity.
▶Can be overhauled
The structure of the product is designed to allow for O/H replacement. It can be used for a long time by replacing consumable parts.
▶Installation is bolt-on
