Original spare parts

Wide stock of original replacement parts of the brands for which we are an authorized agent at your disposal. Think about how genuine parts can benefit your business


Original spare parts allow us to continue offering the manufacturer's warranty for the equipment. 
Remember that the use of generic or modified spare parts may void the equipment warranty


Manufacturers adjust their equipment to allow their customers to maximize their systems performance and production by ensuring updating on their original spare parts


Although they may look and function the same, generic parts are not necessarily the same composition as the specified originals. Parts that are not manufactured to the same tolerances,  holes that are not aligned causing a poor fit during installation, inferior welding which can cause cracks and deteriorate the quality of the entire assembly. Original spare parts have an important attribute compared to generic ones: compatibility


We understand that downtime is extremely expensive, which is why we stock the most common and essential components for the operation of your equipment. For the other components, the usual availability is about 2 weeks - ask us about your case


The use of original spare parts is essential to prolong equipment useful life. Genuine parts are designed to last by meeting factory parameters, thus increasing the intervals between maintenance


Nobody like the manufacturer knows their equipment. Original spare parts are specifically designed for them, with materials and manufacturing processes that require their own quality controls
