Mixing with a Closed Lid: Folding Impellers for Your Batch Size
Although open container mixing is a very common occurrence, mixing in containers with lids can also be accommodated. Folding impellers enable entry through small container openings then expand to their operating diameter with mixer shaft rotation. Mixing with the lid closed can prevent contamination and splashing, thereby minimizing time consuming clean up.
Our standard 2-blade folding impellers, the FP-series, are sized for use with 2” bungs up to 6” IBC tote openings. Bung-entering impellers, whether in pails or drums, expand to 4” or 7” depending on the application and available horsepower from the mixer. Standard mixer models featuring folding impellers have as many as four impellers on the shaft. Larger models, for the 6” tote openings, come in 10”, 12” and 14” sizes.
All folding impellers are available in 304 or 316 stainless steel although those 10” and larger are by quote only. Finally, we offer a number of folding impellers mounted to mixing shafts that are suitable for handheld mixers or drill motors. They range from 2” to 8” in operating diameter.
