Product Overview

The Ductile Iron Water Meter Shell / Meter Body is a high-performance protective casing engineered for residential, commercial, and industrial water volume measurement systems. Acting as the structural foundation of the water meter assembly, our heavy-duty shells protect precision internal metering components (such as impellers, registers, and sensors) from intense pipeline pressure, hydraulic shocks (water hammer), and external mechanical loads.

Key Features & Advantages

Superior Mechanical Strength: Cast from premium-grade ductile iron (GGG40/50), our meter bodies possess far higher tensile strength, impact resistance, and elongation properties compared to traditional grey iron, preventing body fractures under extreme frost or high-pressure surges.
Hygienic Fusion Bonded Epoxy (FBE) Coating: The interior and exterior surfaces are treated with a thick, non-toxic epoxy powder coating. This smooth lining provides exceptional resistance against corrosion and rust, prevents biofilm accumulation, and guarantees absolute safety for public drinking water supply networks.
Precision CNC Machining: Threaded inlets and outlets are finished on high-precision CNC machining centers to ensure precise thread profiles (BSP/NPT) and exact tolerances. This ensures leak-free installation, smooth torque matching, and seamless field connection to municipal pipelines.
Optimized Hydraulic Architecture: Engineered with advanced hydro-dynamic internal chambers to minimize pressure loss, reduce turbulence, and maintain stable flow profiles across the metering mechanism for maximum measuring accuracy.

Manufacturing & Customization Capabilities

As a comprehensive industrial casting facility, we support full custom OEM manufacturing for global water meter brands and utilities:

Custom Logo Moulding: Your company brand name, logo, size markings, and arrows indicating directional flow can be cast directly into the outer surface of the iron shell.
Various Meter Types: Production lines optimized for Single-Jet bodies, Multi-Jet bodies, Volumetric Rotary Piston casings, and heavy industrial Woltman meter housings.
Complete Kit Bundling: We can supply matching brass/iron connection nuts, tailpieces, and EPDM sealing washers alongside the meter bodies to offer your procurement process maximum convenience.
