Peristaltic pumps from Flowrox can pump diverse slurries and dose a range of abrasive, corrosive, viscous or crystallizing media. As the cylindrical rotor rotates along the hose, the process medium gets pushed forward through the hose. At the same time the hose behind the compression point reverts to its original circular shape, creating a suction effect at the pump inlet port. As a result the hose bore gets filled with the medium. No backward flow can occur as the hose is squeezed tight by the roller. The pump eliminates friction, maximizes hose life and lowers energy consumption. 410/636-2250; www.flowrox.us.
