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.

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.

Designed without stuffing boxes, glands, shaft seals or interval valves, there is no danger of external leakage. Only two components are in contact with the fluid-the inner surface of the plastic pump body and the outer surface of the rugged replaceable elastomeric flexible liner. This easy-to-service construction keeps maintenance and downtime low. More than 125,000 of these dependable sealless, self-priming pumps are in service handling aggressive and other problem fluids.

DESIGN AND CONSTRUCTION

UNIQUE DESIGN AND CONSTRUCTION MEANS TROUBLE-FREE OPERATION AND LOW MAINTENANCE


Sealless, Self-Priming, Peristaltic Rotary Pumps, Vanton, Flex-I-LinerA rotor mounted on an eccentric shaft oscillates within the flexible liner, creating a progressive squeegee action on the fluid trapped in the channel between the liner and the body block. Flanges on the flexible liner are pressed to the sides of the body block by concentric grooves on the pedestal assembly and the cover plate. This serves to isolate the fluid to the channel. Pump models are available close-coupled or pedestal -mounted to an electric motor, or air-powered for handling volatile fluids.




Sealless, Self-Priming, Peristaltic Rotary Pumps, Vanton, Flex-I-LinerFlex-I-Liner pumps are available in duplex configuration with manifolds providing common suction and discharge connections, and in sanitary design with flame-polished interiors and quick-disconnect fittings. These pumps are ideally suited for use on a variety of stationary and mobile acid buggies for the transfer of chemicals in laboratory and plant operations, as well as for incorporation on OEM equipment.

Although published data for specific chemicals are available, the most reliable guide to material selection for those difficult-to-pump applications is the Vanton half-century of experience.
