The pulp and paper industry is one of the world’s most important and diverse industries. In addition to the manufacture of pulp and paper, the industry also encompasses tissue-making, containerboard and paperboard manufacture, box and carton manufacture, and bag and envelope production. All of these operations require a pump that can handle solids as large as 35 mm (1-3/8 in). Wilden’s Original metal pumps feature a clamped configuration, lube-free operation and an Ultra-Flex elastomer option that helps ensure a maximum solid passage, maximum mean time between repair (MTBR) and pump reliability. The Original metal pumps also offer Wilden’s Pro-Flo X air distribution system (ADS) which feature an Efficiency Management System (EMS) which allows the operator to improve the parameters required for specific applications.
