The Warman XU pump includes unique casing, impeller and sealing design to ensure lowest possible wear rates in sand and gravel, coal, and many other medium to coarse slurry applications. The XU supercedes the AHU unlined pump, and is in most cases dimensionally interchangeable, fitting directly onto the tried and proven Warman bearing assembly and base. The XU’s unique design is not only cost effective, but easy to maintain.
