Product Overview
Deep, dependable propulsion
The CubeMars DW20 is a 48 V underwater thruster that produces a maximum static (bollard) thrust of over 20 kgf and is rated for operation to about 350 metres. A streamlined nozzle reduces hydrodynamic drag to improve propulsion efficiency and lower electrical load.
The precision-cast aluminium alloy housing resists corrosion and impact, while a two-stage independent sealing chamber and low-friction dynamic shaft seal block sand, dust and water ingress for reliable, low-maintenance operation in demanding subsea environments.
