HILLSIDE, NJ, USA―The portable, non-metallic Flex-I-Liner® rotary peristaltic pump from Vanton Pump and Equipment Corp.
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 has no seals to leak or valves to clog, and can run dry for extended periods without damage. Compact in size with integral handle, it 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 fluid: a thermoplastic body block, and an elastomeric flexible liner that can be replaced in the field without special tools. The rigid body block is of solid polypropylene, UHMW polyethylene, or PTFE, and the molded flexible liner of natural rubber, Neoprene®, Buna-N®, Hypalon®, Viton®, or Nordel® elastomers, eliminating corrosion or contamination associated with metal pumps. The wide choice of thermoplastics and elastomers in which these pumps are available permits their use over the full pH range and for an extensive list of corrosive, volatile and viscous fluids.
A rotor mounted on an eccentric shaft oscillates within the flexible liner, imparting 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 side of the body block by concentric grooves on the bracket assembly and the cover plate, isolating the fluid to the channel.
The pump is suitable for flows from .33 gpm to 40 gpm (1.25 to 151 liters/h) and pressures to 45 psig (310 kPa) at temperatures to 250°F (121°C).
Vanton also manufactures horizontal and vertical centrifugal pumps with all fluid contact components of inert thermoplastics, for flows to 1150 gpm (261 m3/h) and heads to 185 ft (56 m) at temperatures to 275°F (135°C), as well as integrated non-metallic pump/tank systems from 60 to 5000 gallons (227 to 18,927 liters).
