Bulkmatic Square Rotary Vane Feeders are manufactured in two basic types, Models “H” and “L”. Both designs include 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 “L” type valve has a closed end impeller and has adjustable tips fitted as standard. This valve is suitable for applications where the pressure differential is below 30 kPa and the material is non abrasive and free flowing. The “H” 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, soft “flexible” or “hard wearing” impeller tips, body venting, inlet scrapers, “hard chromed”, casings, air purged glands and high temperature construction.

Standard sizes include: 150, 200, 250, 300, 350, 400 and 500. Larger sizes manufactured on request.
