Water ingress is damaging to the system as it causes less lubricity and more corrosion. But by adding 2 to 4% of system oil volume ABCON MARINE-THRUSTER SL (Stop Leak), it not only stops water ingress but also counteracts the negative effects of water in the system.
THRUSTER SL is a stop leak paste that also stops water ingress which is the reverse side of oil leak. Usually it is due to a damaged seal and when ABCON SL is added to the system the teflon based paste forms a barrier which stops water ingress and leakage.
We have a broad assortment of products that work with all types of thrusters. THRUSTER SL stops leaks and water ingress on thrusters’ seals and other similar systems where hydraulic mineral oil based oil is used.
If you have a problem with a leak below 0,5 liters per hour or 10 liters per day, then the THRUSTER SL is your choice. It can stop leakages from rotating and tunnel thruster units and it can stop leakages from controllable pitch propeller systems where there is a suspicion that the O-rings are worn or damaged.
If you have a larger leak than 0.5-2.0 liters per hour, then our THRUSTER SLL is the relevant choice. It has the same properties as THRUSTER SL but we have added some complex particles which increases its effect against larger leaks.
Properties of THRUSTER Stop Leak
All our THRUSTER Stop Leak products have hydraulic oil as a base oil. This means that it is compatible with gear oil and hydraulic oil, and can therefore be used on fixed propellers and CPP propeller systems. It produces a barrier at the surface of the damaged seal where there is water ingress came from. In addition, it protects the bearings and seals against wear and tear thereby reducing the risk of future water ingress.
We deliver to rotating thrusters, both Azimuth and Azipot as well.
The high content of complex particles produces a kind of a sealing layer on top of the seal ring. The effect is that the leakage is significantly reduced or stopped.
When SL or SLL is blended with the existing systems oil the blend produces an excellent lubrication, which due to the teflon content, maintains its’ lubricating effect even if there is some saltwater in the oil.
Above mentioned products are available in Bio degradable base oil. Those products are called THRUSTER BSL and THRUSTER BSLL. All ABCON Bio based products comply with the 2013 EPA VGP requirements as environmentally acceptable.
THRUSTER Stop Leak products are easy to handle and can be added by own staff on board.
When assembling systems with rubber seals a much higher protection can be established by using ABCON MARINE SEAL PROTECT+ on all seal surfaces.
