SUMP-GARD SGK 

Cantilevered bearingless pump has run-dry capability

      Vanton SGK cantilevered sump pumps feature a large diameter, plastic sleeved, alloy steel shaft that eliminates the need for immersed bearings or bushings, allowing run-dry operation for extended periods. Rugged epoxy-coated cast iron motor bracket accommodates NEMA, IEC and standard European motors. Lengths to 2 metres (6 ft) (deeper with tailpipe), flows to 227 m3/hr (1000 gpm) at heads to 64 metres (210 ft)

General

     Pump to be constructed with all wetted components of polyvinyl chloride (PVC), polypropylene (PP), or polyvinylidene fluoride (PVDF) thermoplastic materials. Flows to 850 GPM (193m3/h). Heads to 175 Ft (53m). Temperatures to 275°F (135ºC). Sump depths to 4 Ft (1.2m), deeper with tail pipe.

Advantages of thermoplastics 

  • Greater chemical resistance over thr pH range compared to metals or thermosets.

  • Superior resistance to abrasion compared to metals or thermoset composites.

  • No metallic contamination of the fluid.

  • No peoblems with galling Easier maintenance.

  • No interbatch product contamination Fiberglass composites wick and absorb by capillary action. Solid homogeneous thermoplastics don’t

  • No galvanic corrosion or rusting Metals corrods, plastics don’t

Advantages

  • Providing indefinite dty-rn capability and dependable pertion.

  • Availabe with standard semi-open or closed impellers.

  • Recessed Vortex impeller for slurries and fluids containing stringy materials without impeller clogging.

  • Desingned to handle corrosive, abrasive and haczardous process fluids, wastewater liquids and slurries across the entire pH range.

Specifications 

1. Rugged thermoplastic vertical pump with cantilevered shaft and dry running capabllity.

2. No bearings immersed in the pumped fluid.

3. Large diameter alloy steel shaft isolated from the fluid by a thick sectioned thermoplastic sleeve.

4 Heavy duty extemal ball bearings above the cover plate, housed in an epoxy-coated cast iron motor bracket thet accommodates NEMA, IEC and European standard motors.

5. Casing. casing cover and impeller molded of solid, homogeneous thermoplastics.Columns, reinforcing ribs and other components in fluid contact t e of similar thermoplastic materal.

6. All immersed pump parts and hardware to be homogeneous thermoplastics. No metal or thermoset composites in fluid contact.

7. Quiet running. durable flexible coupling to isolate mtor from hydraulic thrust force

8. Nonmetallic vapor seal to protect metal motor bracket assembly from corrosive fumes

9. Dynamically balanced (semi-open or closed) impeller with imbedded, molded-in stainless steel reiforcing insrt.

10. Standard or custom solid thermoplastic sump cover plae resistant to the corrosive liquid or vapor.

11. Heavy sectioned solid thermoplastic strainer, if required, manufactured of thermoplastic material similar to the construction of the pump
