Applications

Sifters and Sieves

Movement is Tough on Flexible Connectors

Sifters and sieves are used for many and varying products, ranging from dried food to aggregates, pharmaceuticals to liquid chocolate. The movement of the sifter requires a flexible connection between both the feed hopper and the output so the vibration isn't carried through the rest of the stationary equipment.

The most common problem with sifters is poor sealing around the flexible connector leading to a loss of product and serious hygiene issues. The movement of the sifter can easily loosen traditional clamp-and-hose type connections, causing tears and leaks.

The Ideal Sifter Connector Solution

BFM® connectors installed on a potato flour sifter

The BFM® fitting flexible connector system is ideally suited for all oscillating, gyrating or vibratory equipment.

Its unique internal snap-fit system creates a perfect seal every time and is able to withstand pressure and pulling forces (oscillation and vibration) far better than old style clamped systems. No more product leakage or build-up at the connection points.

Our most popular product, Seeflex 040E, is used widely on oscillating machinery in processing plants all over the world.

Aside from its flexibility and transparency, its key advantage is its strength - the Seeflex urethane is made with a unique construction method that makes it superior to other connector products because it won't tear - even if a hole is somehow made in it.

Seeflex also has superior wear resistance so, when installed correctly, it will last much longer than other products on the market.

Advantages of BFM® fitting on Sifters & Sieves

The BFM® fitting flexible connector system is perfectly suited for all oscillating, gyrating or vibratory equipment - here's why:

Snap-in cuff system and strong, resilient material means BFM®'s won't tear and last much longer than traditional connectors.

100% seal ensures there is no more dust leakage, no product loss and no contamination of the work environment.

The quick and easy snap-fit of our BFM® blue band connector means they are fast and simple for all staff to replace.

More durable materials and fast, easy changeovers mean downtime is significantly reduced.

Things That Affect Connector Life on Sifters

There are a number of variables that will affect the life of any connector on a sifter (regardless of whether it is BFM^® or a conventional type), such as:

Positive or negative pressure
Extreme operating temperatures
Additional stress from chemical products (e.g Acid, Caustic)
Extent and duration of operation
Abrasion from product flow
Connector length & installation height

Explore Other Applications and Conditions Using BFM® fittings

BFM® fitting outperforms traditional hose clamp systems in virtually every processing application and condition. Here are some common process applications that are challenging for flexible connectors:

BFM® connector with milk powder feeding into a hopper

If you operate under pressure, we know keeping your product inside your process brings all sorts of challenges, usually around dust control and connector failure.

See how BFM® handles operating pressure.

BFM® connectors installed on a metal detector

Metal Detector applications can be a challenging environment for traditional clamped connector systems because steel cannot be in near proximity to the detector.

See why BFM® is used with metal detectors.

Processors often operate equipment under negative pressure to avoid leaking product out of machinery, but you need to ensure your connectors seal properly too.

Find out why BFM® is ideal for vacuum.

BFM® Spigots installed on product and CIP pipes

Proper cleaning of your pipes and in-line fittings is important during CIP, and having a flexible connector that can handle the chemicals and won't leak is essential.

Watch a BFM® fitting in action during CIP.

Static dissipative connectors like the BFM® fitting range will help reduce the chance of spark discharges occurring that can potentially ignite combustible dust explosions.

Need to see what's going on inside your sifter?

If you have traditional inspection hatches or ports, they need to be opened (risking product spillage and/or contamination) and then replaced to see the product inside your equipment. This takes time and can be difficult depending on the mechanism to seal them closed again.

A solution being used increasingly by manufacturers around the world is the BFM^® Blanking Cap.

"Even though there is a 35mm throw (oscillation) per side, the connector is working perfectly."

- Production Manager, Leading FMCG manufacturer, India

Problems with heavy leakage on a sifter with a significant throw (35mm each side) were plaguing a global leader in the manufacture of home and personal care products. The company were looking for a leak-free solution that was durable and easy to install, so they turned to the BFM® fitting system.
