Materials

There are more than 100 materials for you to choose from

Your requirements determine the nozzle material. Depending on the application, specific operational and application conditions require, for example, robust, lightweight or food-suitable nozzles.

Düsenwerkstoff Messing

Brass

Brass nozzles are still used in many processes, e. g. for low pressure and humidification processes.

Düsenwerkstoff Edelstahl

Stainless steel

The use of chemically and thermally resistant stainless steels such as Hastelloy, titanium, tantalum as well as plastics like PVC, PP, PVDF and Teflon is necessary for aggressive atomizing fluids or operation in corrosive surroundings.

Düsenwerkstoff Siliziumcarbid

Silicon carbide

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.

Düsenwerkstoff Kunststoff

Plastic material

Many nozzles in our portfolio are available in high-quality thermoplastic materials. These nozzles are injection-molded on modern, process-controlled machines.

Certifications and approvals for nozzle materials

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.
 

 
Logo FDA
 
 
The FDA, the U.S. Food & Drug Administration, is a federal agency which overseas those two industries. Materials used in making Lechler products are compliant with the requirements of FDA regulation 21 CFR for use in food applications.
 
 
Logo EG 1935-2004
 
 
The regulation (EC) No. 1935/2004 of the European Parliament regulates general safety requirements to all food and beverage contact materials.
 

Hygiene requirements
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 "PTFE Whirly" and 527 series are 3A-certified, for example.

 
Logo 3-A
 
 
The 3-A® council is an organization in the USA that defines criteria for the cleanability of components in the dairy and food industry. Components and systems are examined to establish whether germs adhere to surfaces or existing soiling can be removed. Components and systems are awarded a »3-A® certificate« only if they are easy to clean or if soil cannot be deposited in the first place.
 
 
Logo EHEDG
 
 
European Hygienic Engineering and Design Group. The EHEDG checks and certifies the hygienic design of components. Its procedure is similar to that of 3-A®. The "HygienicWhirly" series is EHEDG-certified.
 

ATEX approved

 
Logo ATEX-Zulassung
 
 
Lechler offers specially designed nozzle series for use in explosive atmospheres. Different nozzle series have an ATEX approval that was issued by an external certification institute.
