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-GARDŽ pumps incorporate many of the unique design features of the Vanton CHEM-GARDŽ 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-GARDŽ 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.
SPECIFICATIONS
- Pump cover and casing assembly molded from virgin, homogeneous thermoplastics.
- Dynamically balanced, molded thermoplastic impeller with imbedded stainless steel insert. Key driven to assure positive drive.
- 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.
- No bolted-on accessories or blind recesses to impede complete drainage.
- Interchangeable sliding bar pedestal which permits retrofitting with standard Vanton CHEM-GARDŽ is pumps.
- Suction port designed to allow for rotation.
- Retractable front bearing to accommodate most commercially available mechanical seals and simplify seal inspection and servicing.
- Reverse mounted mechanical seal to position the non-metallic face in fluid contact area.
- Alloy steel heavy duty shaft isolated from fluid by thick sectioned thermoplastic sleeve.
- Design to allow for back pull-out.
