But this constant, often aggressive motion can make it difficult to maintain reliable connections. Flexible connectors — which transfer product into and out of the sifter — are placed under significant mechanical stress, especially in continuous operation. Over time, that stress leads to leaks, tears, and unplanned downtime.
It replaces traditional hose clamps with a snap-fit, internally seated connector. Two stainless-steel spigots are welded to the equipment inlet and outlet, and a flexible BLUEBAND™ connector snaps securely inside them. The unique internal snap-band at each end of the connector expands outward to form a 100% dust-tight seal within the corresponding-shaped spigots — no tools, clamps, or guesswork required.
This innovative design delivers a consistent, reliable connection even under vibration, oscillation, or negative pressure — all conditions common in sifting operations.
Traditional hose-and-clamp connectors loosen under vibration or pressure changes, creating leaks and dust emissions. In contrast, BFM® connectors seal from the inside, tightening as pressure increases. With no external clamps to loosen or rub, the connection remains airtight and secure.
The result is reduced product loss, cleaner air, and fewer maintenance interventions — critical for plants prioritising hygiene, product recovery, and safety.
Sifters are exposed to continuous motion and abrasive materials. Rubber or silicone connectors frequently tear or fatigue under these conditions.
BFM® connectors are made from tough, transparent polyurethane (Seeflex 040E) designed for high flexibility, abrasion resistance, and long service life. Plants using BFM® fittings report dramatically fewer replacements and lower maintenance costs — providing a rapid return on investment.
Downtime costs money. Traditional connectors require tools, clamps, and careful alignment — often taking valuable time to reinstall.
BFM® connectors simply snap in and out by hand in seconds. They are always the correct length and alignment, eliminating installation errors. For maintenance teams, this means faster, safer changeovers and more uptime.
A mineral processing facility struggled with frequent hose failures and dust leaks. Each replacement required cutting, clamping, and cleaning — wasting hours of production time. After installing BFM® fittings, the plant went five months without a single connector failure. Dust leakage stopped completely, maintenance cycles were shortened, and connector inventory was standardised. Maintenance teams reported major time savings and easier handling.
A leading food manufacturer in China faced severe dust leakage from silicone connectors on a soy powder line. The screening room filled with airborne flour, forcing operators to wear masks and increasing explosion risk.
For maintenance engineers and production managers, BFM® fittings deliver reliability, hygiene, and ease of use that traditional connectors simply can’t match. The unique snap-fit design ensures a seal that easily handles movement, their durable materials extend lifespan, and tool-free maintenance reduces production downtime.
As proven across industries from minerals to food processing, switching to BFM® fittings can:
If your sieving or sifting operations still rely on hose clamps and manual fitting, it may be time to rethink your approach.
