Yes to Brunvoll quality solutions
Brunvoll’s multiple sealing system with an outer seal,
inner seal and safety chamber keeps seawater out of the
thruster, increasing the lifetime of the seal.
The intermediate safety chamber makes it easy to monitor
the seal condition.
At Brunvoll, we design the gear and mesh to generous
specifications that ensure high endurance and maximum
component life.
Optimum contact patterns ensure robust performance.
Brunvoll designs thrusters both for easy installation and with
generous dimensions for lifetime dependability. We supply
the tunnel complete with stiffener rings as standard.
At Brunvoll we give priority to reliable performance with
engineering that shrugs off punishing real-life conditions.
Brunvoll´s design, high-precision manufacturing and
robust stiffening make it possible to minimize the
propeller tip clearance, resulting in improved overall
thruster performance.
Brunvoll thrusters are fitted with rope guards as a standard
feature to protect the propeller shaft sealing system from
ropes and other foreign objects.
Brunvoll complies with recognized guidelines for tip speed
and cavitation behaviour.
This enhances thruster performance with increased thrust,
less noise and vibration, and lower life cycle costs.
