June 19, 2007

Watson-Marlow Bredel recently launched the 520RE high-pressure chemical metering peristaltic pump with pressure capabilities up to 100psi. The combination of tube elements and pumphead design allows the 520RE to be utilized in applications requiring accurate metering, dosing and transferring of harsh chemicals, including sodium hypochlorite, ferric chloride, sodium bisulfite, fluoride, carbon and lime slurries, polymers, aqueous ammonia, potassium permanganate and caustic slurries. The new 520RE pump is available with a five-year warranty. The new warranty, the first of its kind from a peristaltic pump manufacturer, covers everything except misuse of the pump and consumable items by the consumer and offers free-of-charge repair or replacement. The 520 Series pump offers flows of 55 GPH at 30 psi to 7 GPH at 100 psi. Reliable, accurate and easy to use, the pump covers a wide range of applications including low shear feed for the contamination-free transfer of acids, bases and slurries found in chemical-based industries. Patented LoadSureรข elements guarantee correct loading every time, as well as easy one-minute maintenance with no snaking, twisting or pinching.
