The portable, non-metallic Flex-I-Liner rotary peristaltic pump evacuates drums and totes containing acids, caustics, salts, chlorides and reagent-grade chemicals without corrosion of the pump or contamination of the fluid. The self-priming design of the Flex-I-Liner has no seals to leak or valves to clog, and allows the pump to run dry for extended periods of time without damage. Compact in size, with an integral handle, the Flex-I-Liner fits on drum lids without protruding, and has sufficient lift characteristics to operate from the floor, skid or stand. Only two non-metallic parts contact the fluid: a thermoplastic body block, and an elastomeric flexible liner that can be replaced in the field without special tools. The rigid body block of the Flex-I-Liner is made from polypropylene, ultra-high molecular weight polyethylene or polytetrafluoroethylene (PTFE), and the flexible liner is made from either natural rubber, Neoprene, Buna-N or other elastomers. — Vanton Pump and Equipment Corp., Hillside, N.J.
