The IMS IT-1309 Polisher The IMS Polisher IT-1309, operates at a water pressure of between 6 and 10 bar with water supplied from the ship's fire mains. The polisher weighs only 3 Kilograms.

The polisher features a rotating, flexible disc fitted with the finest DIAMOND polishing pads with grain sizes in the range of P150 (normal standard) to P360 (IMS standard for merchant ships) and even P800 (IMS standard for Navy ships). 

The finish obtained by IMS is better than Rubert Gauge “A” or 0.35 micron Ra (CLA) (best grade on the Rubert Gauge ”A” is 1.00 micron Ra (CLA)). 

In comparison, polishers used by competitors can best reach a finish of P150 and requires longer polishing time to reach this grade. 

The high-grade finish reached by the IMS polisher delays fouling for a longer period than the coarser finish of competitor's polishers.

New propellers have a relative coarse surface, their efficiency can be improved, and cavitation wear avoided by the IMS polishing quality. This is an important marketing feature. A fuel saving of 10% on a newer ship has been reported to IMS after DIAMOND polishing of the ship's propeller.

The roughness of the propeller is measured with a Rubert Gauge before and after cleaning and polishing.

The IMS equipment is light, simple, cheap to produce and very economical in use, as required maintenance is minimal. The tools, which can be handled by one man, cab be easily transported to a ship in any location by means of ordinary transport. This ensures fast, flexible and low cost attendance when called upon.

Today, the IMS have performed work in the following locations:

The main difference in IMS’s technology versus other companies is that the latter use heavy tools usually driven by electricity or hydraulic oils requiring special high pressure hoses, generator sets and pumps. Weights ranging from 150 kilograms and even 300 kilograms are typical for competitors hull cleaners are common. Thus, an operation requiring heavy tools is not flexible and mainly confined to the port where the tools happen to be at the time. And this is not so for the Diamond Propeller Polishing service brought to you by the Phoenix Marine Services Inc.
