Vanton heavy duty self-priming thermoplastic pumps

are ideal for use on mobile acid buggies, for sump

and tank evacuation and emergency overload

pumping. They are often specified for in-line service

where low headroom precludes the use of vertical

pumps, and in other applications where rapid self-

priming from depths to 15 feet is required. Available

in PP & PVDF homogeneous thermoplastics, they are

recommended for the handling of corrosive, abra-

sive, hazardous, toxic and other aggressive fluids.

As with all Vanton thermoplastic pumps, no metal

components are in contact with the fluid being

handled. Even the large diameter steel shaft is

isolated from the fluid by a thick sectioned thermo-

plastic sleeve. No metallic contamination is possible.

Prime-Gard® pumps incorporate many of the unique

design features of the Vanton Chem-Gard® line of

horizontal centrifugals. The retractable front bearing

design provides for quick and easy mechanical seal

inspection. The ability to simultaneously adjust this

bearing close to the impeller minimizes shaft overhang

for higher critical speeds and maximum seal life. The

expanded wide open seal area accommodates most

commercially available seals..

The Vanton Prime-Gard "'design allows for back pull-out

which permits seal replacement without disturbing

existing piping. These self-priming pumps are not subject

to siphoning and loss of prime when shut down. They

have an integrally molded solid thermoplastic priming

chamber and check valve which holds its prime. Once

the pump has been primed, the liquid is trapped in this

chamber and the pump remains primed unless it is

drained for maintenance.
