Neptune Mixer Company”s Cap-Mount mixer design enables installation of a standard, intermediate bulk-container mixer onto any poly tote bin without custom brackets or fixtures. The unit consists of a Neptune Series HGL (430 RPM) mixer fitted with a bolted-style 316 stainless steel bulkhead fitting. The unit supports thorough mixing of materials in semi-bulk shipping containers. It can be easily installed on a container with only minimal modification to the plastic tote bin cap (four bolt holes must be drilled). The cap may also be sent to Neptune for preparation and mounting at no additional charge. Available motors include electric and air motors rated from 1/2 to one HP. Explosion-proof motors are also available. The mixer features a folding propeller that is constructed of 316 stainless steel and is capable of fitting through a two-inch opening. The prop’s operating diameter is nine inches.
