ESSCO offers a complete line of severe duty submersible 100% recessed impeller vortex pumps with protective jackets. These units are designed with extra heavy wall cross sections and extra thickness in the internal wear areas. Each unit is capable of handling long stringy material, large size solids and are especially suited for handling slurries. The protective jackets are available in several materials. The jackets can be static cooled or cooled dynamically with an outside cooling media. In applications with a high volume of abrasives a mechanical seal flush can be routed through the protective jacket without disturbing the cooling media. ESSCO pumps incorporate the vortex pumping action along with a unique pump design which allows for the greatest solids handing efficiency and construction flexibility in the submersible pump field. These units are manufactured by using "State of the Art" technology to produce higher quality castings for longer wear life. Liquid end components of various materials can be mixed to insure the maximum life of the pump without becoming a budget buster. Contact the ESSCO sales office when requesting specific information.
|VOLUTE: Each volute is engineered for maximum life in severe duties. Each ESSCO volute has extra material in high wear areas. Casing thickness is up to 1" in thinnest wear area. The standard volute material is cast iron, for other materials see the "Optional Materials" list.
IMPELLER: ESSCO pumps are available with various impeller designs to allow for high capacity low head or low capacity high head applications. ESSCO utilizes investment cast impellers for higher casting density and thicker vanes and back shrouds which allow for maximum life. By use of the JLI manufacturing techniques ESSCO offers trimmed impellers in extremely hard and difficult to handle alloys. By use of this production technique, impellers can be machined to act as a shredder (for solids coming in contact with the eye of the impeller) or machined to handle solids more delicate in nature. . The standard volute material is ductile, for other materials see the "Optional Materials" list.
WEAR PLATE: For applications with not only aggressive liquids but abrasive material an optional wear plate located behind the impeller can be installed. The wear plate is designed to protect the motor bracket and mechanical seal from particle erosion. The wear plate can also act as a barrier for a seal flushing fluid when a simple wear plate is not sufficient protection against wear created by the pumped media. Again ESSCO utilizes the JLI production method for manufacturing this pump component to ensure the best possible casting quality and material density.
