The combination of the tube elements and pumphead design allows the 520RE to be used in applications requiring metering, dosing and transferring.
The 520 Series pumps from Watson-Marlow Bredel offer flows from 5 GPH at 30 psi to 7 GPH at 100 psi. The pumps have repeatability at 99.5% and can withstand pressures up to 232 psi.
Watson-Marlow Bredel pumps contain fluids within the tube at all times, never allowing the fluid to come into contact with the pump mechanism. Entrained gas is pumped with ease, plus corrosion and damage is restricted to the consumable tubing element.
