Envelop covers have been introduced by Australian Pump Industries to help save Australian industry millions of dollars in corrosion control.  

Originally developed for key asset protection on warships, Envelop protective covers have an important role to play in reducing maintenance and improving process plant reliability. Australian Pump Industries distributes Envelop covers in Australia.  

Envelop covers are being used for Defence applications, particularly in top side asset protection on RAN ships. 

The covers are now standard on most RAN vessels including all ANZAC and FFG Class frigates.  

Developed through funding from the US Navy in an effort to reduce maintenance costs by reducing corrosion, Envelop covers are made from a patented cover material that not only offers waterproof shielding but is a breathable material that prevents moisture build-up on the equipment.  

Traditional waterproof tarps and plastic wraps provide some level of protection but the trapped moisture and salt result in slow deterioration of the asset.      

Envelop protective covers can be tailor-made to suit the asset. For instance, covers have been designed for capstans, deck cranes, torpedos and sensitive electronic equipment on warships.   

A photo modelling service from Australian Pump Industries enables covers to be quickly designed and produced to suit virtually any application.   

A deck crane cover designed by Australian Pump shields the entire machine including its sensitive hydraulic control equipment, providing virtually 100% corrosion protection, says Aussie Pumps’ Adrian Fiatarone.  

The US Navy is currently outfitting every surface ship with Envelop covers.  

Envelop covers are not only suitable for operational assets, but are also useful for long term storage of equipment. Important spare parts can be protected from extreme humidity, dust, sand degradation and UV exposure.  

A 50-tonne crane hydraulic motor cover designed by Aussie Pumps provides full protection without impeding function or requiring removal before operation, says Fiatarone.
