Neptune Mixer Co., a division of Neptune Chemical Pump Co., announced that its Series HGL mixers are now available in both electric and air-driven models. The Series HGL mixers are ideal for intermediate bulk container (IBC) and poly tote applications found within the wastewater treatment and chemical industries. Explosion-proof models are also available. Neptune’s HGL bulk-container mixers are vertically mounted. These gear-reduced mixers can turn larger props at 350 rotations per minute for thorough mixing. The 316 stainless steel propeller folds to fit through a 2-inch opening and opens to a 9-inch diameter when operating. (
