Made for the pulp and paper industry, the peristaltic pump’s combination of tube elements and pumphead design allows concentrated, neat dyes to be transferred directly to paper machines. The pump offers flow rates of 55 GPH at 30 psi to 7 GPH at 100 psi. Changing dye color is completed in one step by simply switching the tube element. There is also no need to make down the dye or flush out the pump. The pumps and patented elements guarantee correct loading every time, as well as easy one-minute maintenance with no snaking, twisting or pinching, according to the manufacturer. These self-priming pumps accommodate flow rates from 0.1 microliter to 350 gpm and are extremely durable, withstanding pressures up to 232 psi. There are no internal universal joints, valves, dead corners or glands to impede flow and these pumps are reversible for back flushing lines. They can also run dry indefinitely without damage and provide up to a 30-foot suction lift.
