Operate at Depths up to 20,000 Feet Under the Sea

Goldline S-Series submersible motors have proven seaworthy in countless applications, in salt and fresh water and at shallow depths to the ocean floor. These innovative oil-filled, pressure-compensated brushless servo motors are designed to operate at underwater pressures up to 10,000 psi. The stainless steel and aluminum nickel bronze alloy housings with specialized shaft, seals, bearings and connectors withstand the pressures, shocks and corrosives that underwater applications are subject to while requiring minimal maintenance.

Get Custom Performance for Underwater Control and Efficiency

Square Robot has engineered an innovative battery-operated submersible vessel that inspects fuel and oil storage tanks for cracks, corrosion and other defects while the tanks remain in service — eliminating the need to drain them for human inspection. For precise navigation, extended battery life and long-term reliability, this submersible robot uses highly energy-efficient thruster motors with specialized windings and integrated feedback devices.
