FLEX-I-LINER peristaltic type rotary pumps transfer, sample or meter acids, caustics, solvents, salts, chlorides and reagent grade chemicals — even viscous fl uids and slurries containing soft solids and abrasives. Only two non-metallic parts contact fluid — the rugged thermoplastic body block and durable, replaceable elastomeric flexible liner. This easy-to-service construction keeps maintenance and downtime low. The wide choice of thermoplastics and elastomers in which these pumps are furnished permits their use over the full pH range and for an endless list of corrosive, volatile, abrasive clear and viscous fluids, as well as for vacuum service and gas transfer. The gentle peristaltic pumping action minimizes foaming, prevents settling out of suspensions and permits safe handling of latex emulsions and other shear-sensitive liquids. Seal less, non-metallic and self-priming, FLEX-I-LINER pumps operate in either direction, wet or dry, in any position. Their unique design eliminates shaft seals, glands, internal seals, stuffing boxes and other potential sources of leakage. Offered in Pedestal Mount and Close Coupled models, FLEX-I-LINER pumps can be furnished with electric motors, with rotary vane air motors or with variable speed drives for metering purposes. 

 

Over 140,000 of these dependable seal less, self-priming pumps are in service handling aggressive and other problem fluids. Pumping is accomplished by a rotor mounted on an eccentric shaft rotating within a flexible elastomeric liner. This creates a squeegee action on the fluid, which is trapped between the outer surface of the liner and the inner wall of the body block

Only the rigid thermoplastic body block and the flexible elastomeric liner contact the fluid being pumped. Body blocks are available in polypropylene, UHMW polyethylene and Teflon. Flexible liners can be furnished in natural rubber, Neoprene, Buna-N, Hypalon, Viton, Nordel.
