CubeMars DW20 Underwater Thruster

Product Description

The CubeMars DW20 underwater thruster is a high-performance propulsion system designed specifically for medium-class remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs).

Rated at 48 V, it delivers a maximum static thrust of ≥20 kgf and is rated for operation down to a depth of approximately 350 meters. The thruster features a precision-cast aluminum alloy housing, a dual-chamber independent sealing structure, and a low-friction dynamic shaft seal—collectively reducing hydrodynamic drag while enhancing propulsion efficiency and long-term reliability in demanding subsea environments.
