Over the years, GemmeCotti has created its own range of pumps for acids designed and manufactured by its experienced team of experts that was able to produce technologically advanced pumps which are resistant to aggressive chemical agents and that are now valued the world over. GemmeCotti pumps are successfully used in many different industries including: chemical and petrochemical, pharmaceutical, oil refinery, electroplating, printed circuits, electronic, photography, military, water treatments, biotechnology, paper mills, textile, sugar plants, food processing, dairies and many others. THE QUALITY MANAGEMENT SYSTEM In 2007 GemmeCotti obtained the ISO 9001:2000 certification, a clear proof of their dedication to constant improvement and desire to offer high quality service and products. The quality management system has then been updated according to the requirements of the new ISO 9001:2008. With the constant desire to meet customers’ expectations and offer them the best support and products, Gemme Cotti constantly seeks to improve every business process: from the technical and production department, to the marketing and sales office. Every aspect is developed and organized so that the company can be competitive and flexible on the pump market and can maintain the position of leading supplier of pumps for chemicals. 4 www.gemmecotti.com PRODUCT QUALITY GemmeCotti’s first aim is to understand the customers’ requirements and supply the best product suitable for their needs. The sales and technical office are able to select the right pumps model and the recommended material for the requested application using the company’s know-how together with up-to-date software tools. Once chosen, the pump can be manufactured. All the parts of the pumps come from qualified suppliers and they are checked and machined carefully by highly skilled GemmeCotti personnel to assure the compliance to the technical constructive drawings. After the assembly our pumps are then all tested one by one in our new and modern test bench to check the performances and the good functioning before shipping them to the customer. Thanks to a fully stocked warehouse, GemmeCotti can store most of the parts of the standard pumps, so that in case of urgent request, we are able to supply rapidly to the customer both pumps and spare parts. OUR MISSION GemmeCotti corporate policy is oriented to quality and continuous improvement. Our main purpose is to become “Privileged supplier” of our customers for pumps for acids and dangerous liquids and to maintain this status. We want to offer the best products and the best service possible with an extremely reduced delivery time. GEMMECOTTI IS ONLINE GemmeCotti offers the possibility to always have up-to-date information about the company and all the pumps through the website www.gemmecotti.com. It is designed so that every single pump model has its own detailed description and technical drawings and, from a dedicated section, it’s possible to download all the PDF catalogues. Moreover, the customer using a chemical resistance chart can proceed with a first selection of the pump type and material suitable for his application before contacting our sales office.
