Model 4010 Rapid Flow Impeller Filler is designed to fill valve style bags with high bulk density powder products such as Portland and masonry (plastic) cements, fine ground gypsum, hydrated lime, fly ash, fine ground calcium carbonate, talc, silica flours, insecticides, clay products, stucco and similar products. The products can contain some sand, but it must not be greater than 150 mesh. Bulk densities should remain greater than 50 pounds per cubic foot.

Some advantages of Impeller packers include low overall height of around 66” and lower maintenance costs compared to auger packers. Normal life of an impeller is one year in average duty service. An impeller packer will fill a bag 2-3 times faster than an auger packer, and generally with less dust than an air packer. Controls are very simple, and maintenance is minimal.

How it Works:

The 4010 Rapid Flow is a stand-alone unit with a separate drive motor for each impeller. The motor driving the rotor stops when a bag is not filling, and a cross pinch tube is used to stop the product flow into the bag at the end of the fill cycle. The rotor is equipped with “wing augers” to help feed product smoothly into the impeller. The 304 stainless steel impellers and wing augers are replaceable or rebuildable. Multiple unit configurations are possible, with approximately 24” between spout c/c, and in configurations of up to 3 units.

  • Fill Rates: up to (8) 94 lb. bags or (10) 50 lb. bags per minute for cement. (12) to (14) 25 lb. bags per minute for tile grouts.
  • Fill Weights: 20 lbs. to 110 lbs.
  • Weight Accuracy: +/- 6 to 8 ounces from target weight (+/- 2 to 4 oz. with load cells).

Note: Rates and accuracy are dependent upon maintaining a constant de-aerated head pressure. For Portland/masonry cement, 8000 lbs. per spout of head is recommended. For denser products like tile grouts, the head should be limited to 1000 lbs.
