Sifter Solutions

Sifters and screeners are used to classify, scalp and safety screen powders and liquids.


Vibratory, gyratory and centrifugal actions are used to spread and convey material over the screen surface. The movement of the sifter requires a flexible connector on the inlet and outlet connections so that the motion is concentrated on the screen surface and not carried through to the upstream and downstream stationary equipment. This constant movement puts stress on the flexible connections between equipment which can easily loosen traditional clamp type flexible connectors, resulting in common problems like poor sealing, leaks and failures.


BFM® fitting connection system is ideally suited to all vibratory, gyratory and oscillating equipment due to the superior wear and tear resistance of the Seeflex urethane connector material and flexibility to allow freedom of sifter movement for optimum screening efficiency. The unique snap-in system of the BFM® fitting connector design seals from the inside and tighter under pressure creating a perfect seal every time with no internal crevices or ledges for product to build up in addition to being fast and easy to remove and replace.


BFM® fitting connectors provide visibility of the product flow while eliminating any dust leaking into the production area, resulting in fewer clean-ups required and a safer environment for operators.


BFM® fitting caps when installed on sifter covers provide added visibility during operation without need to remove covers or expose the product to potential contamination.

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
