Watson-Marlow”s 520 “neat dye” peristaltic pump is designed for pulp & paper applications. The pump”s combination of tube elements and pump-head design enables neat dyes to be transferred directly to paper machines. There is no need to makedown the dye or flush out the pump since dye color can be changed in one step by switching the tube element. All pumps feature patented LoadSure elements, which are designed to provide one-minute maintenance and correct loading with no snaking, twisting or pinching. The elastomer tubing resists abrasive wear, providing predictable pump life costs, as the tube is the only part that will need replacing. The 520 pump offers flowrates of 55 GPH at 30 PSI to 7 GPH at 100 PSI.
