IP68 waterproof motors

This motor is waterproof according to protection class IP68 even under extreme conditions. IP68 waterproof motors can be operated permanently underwater and applied in dusty environments. It is seawater-resistant and withstands a water depth of up to 40 metres.

Additional features

Our IP68 waterproof motors are operable in anti-clockwise and clockwise rotation and are resilient to standstill. Of course, they are oil- and silicone-free as standard.

Saving energy with efficient technology

Extremely efficient and high-performance, our radial piston motors provide high torques while consuming only a minimum of compressed air, making it the pioneering drive technology for the future. Our motors save energy and costs of up to 90% compared to other drives such as the vane motor.
