Vanton FLEX-I-LINER® peristaltic type rotary pumps transfer, sample or meter acids, caustics, solvents, salts, chlorides and reagent grade chemicals — even viscous fluids 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. (See Chemical/Material Resistance Chart):

 

The gentle peristaltic pumping action minimizes foaming, prevents settling out of suspensions and permits safe handling of latex emulsions and other shear-sensitive liquids.

Sealless, 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.

Every Vanton pump is fully tested to verify performance with all data permanently recorded.

Over 140,000 of these dependable sealless, 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®.
