After three years of research and having identified what it says is a revolutionary new hose material, Watson-Marlow Bredel has launched PetroProof — claimed to be the world’s first peristaltic pump capable of handling hydrocarbon liquids in continuous duty applications.
Until now, such material, along with organic solvents and mineral oils, has been chemically incompatible with the rubber-based materials used in peristaltic tubes and hoses. Watson-Marlow Bredel’s new TEP (thermoplastic elastomer) is capable of matching chemical resistance with the properties needed in a long-life hose.
PetroProof differs from conventional Watson-Marlow Bredel hose pumps in that the hose is strong enough in its own right. It doesn’t require internal resistance and is suitable for pressures of up to 72psi.
Also the pumphead uses three pressing shoes as opposed to the standard two in this type of pump.
