*Impeller outer diaMetre: 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 diaMetre 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.
