the warman pump: trusted name in slurry pumps since 1938. slurry transportation is at the heart of a mine site, so its crucial your pumping equipment is up to the task. Is your existing pump vibrating, cavitating or leaking? does your pump shaft keep breaking? maybe the crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing segments. As a result of the specific geometry between roll body and crushing segment an optimum tight fit is achieved, thus being able to stand up to the high crushing forces.
