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 the full line of homogeneous thermoplastics, they are recommended for the handling of corrosive, abrasive, hazardous, toxic and other aggressive fluids.

A solid plastic 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.

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. There is no danger of metallic contamination. Prime-Gard pumps incorporate many of the unique design features of the Vanton Chem-Gard line of horizontal centrifugals.

These include the retractable front bearing construction which accommodates all commercial seals and simplifies seal inspection, and the sliding bar pedestal which assures perfect shaft alignment. These pumps are interchangeable with other Vanton Chem-Gard centrifugal pumps.

PRIME-GARD Pump Specifcations

1. Pump casing and cover to be molded from virgin, homogeneous thermoplastics.

2. Dynamically balanced, molded thermoplastic impeller with imbedded stainless steel insert. Key driven to assure positive drive.

3. Integrally molded, one-piece thermoplastic priming chamber which includes accessible check valve, inner casing and internal fluid passages. Construction holds prime on shut down, unless drained for maintenance.

4. No bolted-on accessories or blind recesses to impede complete drainage.

5. Interchangeable sliding bar pedestal which permits retrofitting with standard Vanton Chem-Gard pumps.

6. Suction port designed to permit rotating 360 degrees.

7. Retractable front bearing to accommodate most commercially available mechanical seals and simplify seal inspection and servicing.

8. Reverse mounted mechanical seal to keep metallic face out of fluid area.

9. Alloy steel heavy duty shaft to be isolated from fluid by thick sectioned plastic sleeve.

10. Construction to allow for back pull-out to facilitate seal replacement.
