Vanton FLEX-I-LINER peristaltic type rotary pumps transfer sample or meter acids, caustics, solvents, salts, chlorides, and ultrapure chemicals – even viscous fluids to 6000 SSU (1300 centistokes) and slurries containing soft solids and abrasives. They are suitable for clear, volatile liquids as well as for vacuum service and gas transfer. Gentle pumping action permits pumping latex emulsions and other shear-sensitive liquids. These sealless, self-priming pumps operate in either direction, wet or dry in any position. Unique design eliminates shaft seals, stuffing boxes, and other potential sources of leakage. Only two non-metallic parts contact fluid-the rugged body block and durable elastomeric flexible liner. Maintenance is easy and no special tools are required. Flows from .1.26 lpm (33 gpm) to 9m3/hr (40 gpm) at pressures to 310kPa (45 psig). Temperatures to 121°C (250°F).
