CHEM-GARD PG
PG PRIME-Gard pump is self priming
This heavy-duty, self-priming, centrifugal pump handles flows to 40m3/hr (175 gpm), making it ideal for acid buggies, sump and tank evacuation, and emergency overload pumping. It is often specified for in-line pump service where headroom prevents the use of vertical pumps, and other applications where self-priming from depths to 4.6 metres (15 ft), may be required. These pumps are available in the full line of homogeneous thermoplastics, and the pedestals are inter-changeable with all standard CHEM-GARD models.
GENERAL
Pump to conform to ANSI B73.1 process pump standards, and be constructed with all wetted components of polyvinyl chloride (PVC), polypropylene (PP), polyvinylidene fluoride (PVDF) homogeneiu thermoplastic materiastic materials Flows to 1150 GPM (26m3/h). Heads to 185 Ft (56m). Temperatures to 275°F (135ºC).
SPECIFICATIONS
1. Plastic sleeve isolates the stainless steel shaft from the fluid being pumped.
2. O-ring seals between the plastic sleeve and the impeller, and betwwn the impeller and the locknut, assure no metal contact with solution.
3. The retractable front bearing can be pulled back n parallel bars for easy seal inspection, reduced maintenance and assuring perfect alignment
4. Heavy duty, self aliging bearings widely spaced on the shaft, fo maximum stability and long seal life.
5.The relatively short, large diameter stainless steel shaft with generous radii significantly reducesmstress concentrations and avoids the potential for the impeller.
6. Camlock bearings are utilized to allow easy adjustment of the impeller.
7. Heavy sectioned static casing O-ring prevents leaks and blow outs.
8. Key driven, dynamically balanced molded impeller design with stainless steel imbedded insert ensures positive drive provides additional rigidity to impeller at higher temperatures and pressures, and prevents damage in case of reverse rotation Semi-open or closed impellers are available.
9. Heavy wall,homgeneous molded thermoplastic casing and casing covers
10. Quick serviving back pullout construction per ANSI B37.1 and leveling bolt to facilitate removal and reassembly
11. Heavy duty epoxy coated metal armor serves to carry nozzle loading
