Bulkmatic Blow Through Rotary Vane Feeders are designed for the pneumatic conveying of products that do not easily vacate the impeller pockets. The inlet and outlet pipe of the blow through rotary feeder are designed to clear out the pocket as the impeller rotates into the air stream.

The design includes outboard bearings, machined stuffing boxes and “oversized” impeller shafts. The inlet ports have “V’s” cast into the side wall to create a scissor cutting action between impeller blade and casing. This ensures smooth rotation without the “chopping effect’ experienced with other valves. The result is increased bearing and impeller tip life.

The “BT” type valve has an open ended impeller and has adjustable tips fitted as standard. This valve is suitable for applications where the pressure differential is below 100 kPa and is ideal for use in Pneumatic Conveying Systems and heavy duty applications. Various options are available including different materials of construction such as stainless steel, body venting, inlet scrapers, “hard chromed” casings, air purged glands and high temperature construction.

Standard sizes include: 200, 250, 300, 400 and 500. Other sizes manufactured on request.
