Sacrificial Anodes

Sacrificial anodes are designed with more negative electrochemical potential than that of the structure of metal. This results in the polarisation voltage potential becoming a lot more negative. Polarisation is caused by the current flow from the anode to the cathode.

Aluminum, Magnesium or Zinc anodes are supplied to specification. Bolt or weld on options are available. All standard shapes are supplied in a variety of weights, and the options mentioned above. 

We source our sacrificial anodes locally as well as internationally so cover a large variety of options.

Anchors, Chains, Shackles & Mooring Bridals

Please supply full details of your requirements and a quote will be supplied.

Fibre and Steel Wire Ropes

Fender Tyres

Aircraft tyres are the best structurally engineered tyres in the world, withstanding pressures more than 100 times that of a truck tyre. They are made from natural rubber and are much less susceptible to weathering thereby on average outlasting truck tyres 4 to 1. They are exceptionally strong and durable and don’t rust. Used aircraft tyres are particularly suitable as boat or dock fenders.

Centrifugal Filters

Range of Mann & Hummel separators offered

In todays modern diesel engines fuel filters are becoming more and more important in keeping dirt and water out of the diesel injection system. Common rail engines, with their smaller injector sizes and higher injection pressures, are especially susceptible to dirty diesel and water contamination. Separ Fuel filter units are specially designed to filter out the majority of water and impurities out of diesel before it reaches the critical parts like the injector pump and injectors. The SWK range has a special 5 stage filtering process which ensures extra longevity of the filter cartridge, as well as having a unique backflushing ability which also helps prolong the life of the diesel filter.

A special unit called a ‘centrifuge’ can also be retrofitted to some diesel engines. These units use centrifugal force to clean oil and can remove dirt particles as small as 1 micron, keeping the oil cleaner for longer. This can lead to longer running times between oil changes. The centrifuge is fully serviceable and can be cleaned within a matter of minutes. The centrifuges are used primarily used on diesel engines to remove abrasive soot particles, however these units can also be used on bulk oil storage tanks, as well as oil tanks of hydraulic systems, particularly where dusty conditions are encountered.

In today’s tough economic climate it’s even more essential to protect your investment by maintaining the quality of your lubricating oils. This is easily achieved with the correctly specified product, most suited to your particular application. 

Please contact for further information on specifications and applications.

Separator Spares

Westfalia and Alfa Laval separator spares

Rotor Motive can supply genuine or aftermarket spare parts and on occasion reconditioned spare parts.
Complete used units are also available on an ad hoc basis. Please enquire for further information.

Propellor Repairs

Propeller repairs by Rotor Motive are undertaken by Lloyds coded welders.
The type of material that the
propeller is manufactured from will determine the type of repair undertaken, either welding or brazing.

This repair will include the necessary rebalancing of the unit.
A polishing service is also available and technicians are available to travel away from the main centres.

Johnson Cutlass Bearings

Sleeve and Flanged Bearings

These water lubricated bearings have set industry standards for decades in the harshest working environments, earning the trust of more marine professionals than any other bearing.

Please call us to discuss your requirements.
