CHEM-GARDÆ PG

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, abrasive, 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 thermoplastic sleeve. No metallic contamination is possible.

PRIME-GARDÆ pumps incorporate many of the unique design features of the Vanton CHEM-GARDÆ 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-GARDÆ 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.
