A totally-enclosed fan-cooling outdoor motor made by Hitachi is used as standard.
Possible to assemble the propellers with 2 stages for the models of 1 stage. (The diameter of propellers shall be smaller in case of 2 stages than the standard 1 stage.)
Possible to assemble the shaft seal for 0.2kW or larger models.
Possible to assemble the 6P motor for 0.4kW or larger models. Please contact us for further information.
Racing (no-load operation) is strictly prohibited.
Dilute liquids have a viscosity of about 0.1 Pa · s (100 cP), and medium-viscosity liquids have a viscosity of about 0.1 to 0.5 Pa · s (100 to 500 cP).
