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.

Unlike conventional designs, once
these pumps have been primed, they
stay primed, even on shut down.
