APPLICATIONS q Agitation and mixing of liquids containing solid suspensions. q Cataphoresis plants. q Stainless Steel units ideal for steam heating of liquid in tanks where uniform heat distribution over a large area is required. High efficiency. Wide range of flow capacities. Outstanding resistance to erosion/corrosion. Tapered inlet reduces wear and resists clogging. High velocity jet stream for maximum agitation/mixing. Typical turnover ratio of 3:1. q Produces a high velocity straight jet. q Induces the surrounding liquid into the jet stream. CONSTRUCTION AND MATERIALS SPECIAL PURPOSE q One piece design with no internal components. q Available with 3⁄8”, 1⁄2” and 3⁄4” Male BSPT thread. q Available in 316 Stainless Steel or Glass filled Polypropylene (Polyglass).
