Watson-Marlow Bredel”s PetroProof pumps are industrial, high-pressure hose pumps that support petrochemicals such as hydrocarbons and oils. The PetroProof line uses an oil-resistant hose material, which shelters the product from contact with any metal or moving pump parts, making the pump a good fit for abrasive and corrosive products. Finite element modeling (FEM) was used to design the various PetroProof hose sizes to ensure maximum performance under a range of service loads. PetroProof hoses are optimized for compression force, internal pressure, and expected lifetime. With no valves or seals to clog, PetroProof hose pumps require minimal maintenance and provide a cost-effective alternative to traditional diaphragm, progressive cavity, and rotary lobe pumps. Every Watson-Marlow Bredel peristaltic pump is an inherent metering pump with repeatability at 99.5 percent. Many models include integral digital drives and displays in washdown enclosures. These self-priming pumps accommodate flowrates from 0.1 microliter to 350 GPM and can 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 backflushing lines. They can also run dry indefinitely without damage and provide up to a 30 feet of suction lift.
