Precise Performance Where It Matters Most: BFM® Weighing Bellows
When it comes to material processing, accuracy in weighing can make or break the efficiency of your operation. For applications like loss-in-weight feeders or precision dosing systems, even the smallest amount of force transfer or product buildup can skew results. That’s where the
BFM® Weighing Bellows step in—designed specifically to eliminate those variables and provide a seamless, reliable solution for sensitive weighing environments.
Built for Precision – Engineered for Strength
At Siftex, we’re proud to supply BFM® Weighing Bellows—crafted from Seeflex 040E, a clear, ether-based thermoplastic polyurethane alloy. This material is not only tough and flexible, but it’s also designed to withstand constant movement without fracturing or tearing. The smooth, glossy finish resists product buildup and ensures long-lasting durability in high-demand environments.
But the real secret is in the shape. The unique bellows form effectively isolates vibration, minimizing force transmission to weighing equipment downstream. Whether you're dosing, feeding, or monitoring materials, that isolation means more accurate results and less recalibration.
Perfect Fit, Every Time
One of the standout features of BFM® connectors is the snap-fit system. Just like their standard flexible connectors, the Weighing Bellows attach to spigots with a simple, secure push-and-twist motion. There’s no need for hose clamps or manual adjustments—just consistent alignment and easy installation, every time.
That precision fit doesn’t just make maintenance easier; it enhances hygiene, prevents leaks, and reduces downtime—critical in industries where precision and cleanliness go hand-in-hand.
Sizes Available: Compact, Standardized, and Ready to Go
The BFM® Weighing Bellows are available in the most commonly used sizes:
- 4" ID
- 6" ID
- 8" ID
All in a compact 3” length. These standardized options are ideal for a range of weighing applications, offering consistency and compatibility with existing BFM® systems.
