Water meter bend malleable cast iron

  Datasheet (PDF)

The Georg Fischer malleable cast iron galvanized water meter bend 933 provides a rigid, vibration-resistant 90-degree offset connection engineered specifically for potable water metering manifolds, municipal utility service entries, and technical distribution lines. Manufactured from high-grade whiteheart malleable cast iron and finished with a hot-dip galvanized protective layer, the component delivers exceptional mechanical strength, structural integrity, and long-term resistance to corrosion and scaling in demanding drinking water systems. The fitting combines a sturdy dual-hole mounting bracket flange with an extended-sweep bend profile that transitions seamlessly into a parallel external fastening thread conforming to EN ISO 228-1 class B. This integrated mounting bracket includes 18 mm mounting apertures arranged on a 126 mm transverse spacing with an 83 mm depth profile, enabling rigid mechanical anchoring to walls, mounting rails, or interior brackets within water meter chambers. By absorbing torsional forces and pipeline vibrations, the rigid mounting base prevents pipe strain and preserves joint integrity during periodic water meter servicing, assembly, and calibration. The outlet connection is engineered with precision-machined G-threads in sizes ranging from 3/4 inch to 1 1/4 inch, establishing a dependable flat-sealing surface when combined with flat seat union nuts, water meter couplings, or the companion Georg Fischer 933a counter flange. The hydraulic sweep contour minimizes flow turbulence, localized pressure drops, and noise transmission before fluid enters the measurement section, ensuring stable volumetric metering and enduring operational reliability across commercial, domestic, and industrial distribution infrastructures.
