Your requirements determine the nozzle material. Depending on the application, specific operational and application conditions require, for example, robust, lightweight or food-suitable nozzles.
Brass nozzles are still used in many processes, e. g. for low pressure and humidification processes.
The use of chemically and thermally resistant stainless steels such as Alloy 22, titanium, tantalum as well as plastics like PVC, PP, PVDF and Teflon is necessary for aggressive atomizing fluids or operation in corrosive surroundings.
In case of high demands on wear resistance, we provide you with precision nozzles made of hardened stainless steel, hard metals, oxide ceramics or silicon carbide.
Many nozzles in our portfolio are available in high-quality thermoplastic materials. These nozzles are injection-molded on modern, process-controlled machines.
Lechler precision nozzles – especially for tank and equipment cleaning – are made of extremely high-grade materials that are designed to meet high requirements such as resistance to cleaning chemicals or temperature influences. The large choice of different materials – e.g. 316L SS, PVDF, PEEK or PTFE – allows nozzle selection customized to the individual application and operating conditions. In addition, the materials used for the tank and equipment cleaning nozzles are perfectly matched to each other and are thus characterized by very low wear.
In addition to the requirements for material resistance and wear, the materials must also be food grade for use in the beverage, food and pharmaceutical industries. Depending on the application area, the materials must meet different demands. A large number of the materials used for Lechler tank and equipment cleaning nozzles comply with the requirements of the FDA or conform to (EC) 1935/2004.
Lechler‘s tank and equipment cleaning nozzles are designed so that they meet hygiene requirements. This is reflected, for example, in the self-draining function, minimized dead space in the nozzles as well as an external design without unnecessary gaps and edges. At the same time, the nozzles are designed with the lowest possible surface roughness. Lechler also offers specially certified nozzles for particular hygiene requirements. The "Teflon Whirly" and 527 series are 3A-certified, for example.
