Watson-Marlow’s 520RE high-pressure chemical metering pump is a good fit for applications requiring accurate metering, dosing and transferring of harsh chemicals. The pump offers flows to 55 GPH and pressures to 100 PSI. The pump covers a range of applications including low-shear feed for contamination-free transfer of acids, bases and slurries found in the chemical-based industries. Patented LoadSure elements ensure correct loading, as well as one-minute maintenance with no snaking, twisting or pinching. Watson-Marlow pumps contain fluids within the tube at all times, not allowing fluids to come into contact with the pump mechanism, ensuring gentle, low-shear handling of fluid. Entrained gas is pumped easily, and corrosion and damage is restricted to the consumable tubing element. This helps provide predictable life costs for the pumps, as the tubing is the only part that will need replacing.
