Eccentric Offset Design – Centerlines are offset to maintain a flat bottom alignment in horizontal piping, ensuring complete drainage and preventing fluid pooling
DIN 11852 Standard Compliance – Manufactured to DIN 11852 / EN 10374 specifications, the leading European standard for hygienic tubing systems
Smooth Crevice-Free Transition – Cold-formed construction ensures a seamless, crevice-free internal surface that eliminates bacterial harborage sites
High Corrosion Resistance – Constructed from premium 304 and 316L stainless steel for exceptional durability in demanding hygienic environments
Weld-End Connections – Designed for orbital or TIG welding, providing permanent, hygienic, and leak-proof joints
Wide Size Range – Available from DN15 to DN150 with various inlet-to-outlet combinations
Superior Surface Finish – Internal surface finish Ra ≤ 0.8μm standard, with electropolished options available for enhanced cleanliness
CIP/SIP Compatible – Fully supports Clean-In-Place and Sterilize-In-Place procedures-
Prevents Pump Cavitation – The eccentric (flat-top) design allows air to pass through the system immediately, protecting expensive pumps and flow meters from cavitation damage – a critical advantage over concentric reducers in horizontal pump suction applications
Complete Drainage – Flat bottom alignment ensures no fluid pooling or product retention, reducing contamination risks and improving product yield
Superior Hygiene – Smooth, crevice-free internal surfaces minimize bacterial growth and meet GMP/HACCP standards for sterile processing
Enhanced CIP Efficiency – Optimized internal geometry reduces cleaning time and chemical usage, ensuring rapid and effective cleaning cycles
Versatile Applications – Suitable for food processing, beverage production, dairy, pharmaceutical, biotech, brewery, and fine chemical industries
Permanent Reliability – Weld-end connections provide permanent, leak-proof joints with no seals or gaskets to fail
Orbital Welding Ready – Extended tangents and strict dimensional tolerances ensure consistent weld bead penetration during automatic orbital welding
The D32W DIN 11852 Eccentric Reducer operates as a diameter transition component within a sanitary welded piping system:
Diameter Transition – The reducer connects a larger diameter pipe to a smaller diameter pipe, gradually reducing the flow cross-section to control fluid velocity and adapt to downstream equipment requirements
Eccentric Flow Path – Unlike concentric reducers that maintain a common centerline, the eccentric design offsets the centerlines, creating a flat bottom that keeps the pipe invert level
Weld-End Installation – Both ends are welded (orbital or TIG) to mating pipes, creating a permanent, hygienic, and crevice-free joint that eliminates leak points
Air Management – In horizontal installations, the flat-top orientation allows entrained air or gases to flow through rather than becoming trapped, preventing cavitation in downstream pumps
Complete Drainage – The flat bottom ensures full drainage during CIP cycles, preventing product residue accumulation and bacterial growth

Q: What does "D32W" mean?
A: "D32W" is a product series/model designation for this DIN 11852 eccentric reducer. It identifies the specific configuration and size range of the fitting.
Q: What is the difference between eccentric and concentric reducers?
A: Eccentric reducers have offset centerlines and maintain a flat bottom, making them ideal for horizontal piping where complete drainage and air elimination are critical. Concentric reducers maintain a common centerline and are typically used in vertical piping applications-.
Q: Why choose an eccentric reducer for horizontal pump suction?
A: In horizontal pump suction applications, a concentric reducer can trap air at the top of the pipe, causing cavitation that damages pumps. An eccentric reducer with flat-top installation allows air to pass through immediately, protecting expensive equipment.
Q: What materials are available?
A: Our D32W DIN 11852 Eccentric Reducers are available in 304 stainless steel and 316L stainless steel. 316L offers enhanced corrosion resistance for more demanding pharmaceutical and biotech applications.
Q: What certifications do your products have?
A: Our fittings are 3A Sanitary Standards certified, CE certified, and manufactured under an ISO 9001 certified quality management system. Material test reports are supplied with each order.
