• Solid Kynar or PTFE heads to eliminate permeability and liner separation problems
• Concentric casing design for better flow patterns than other centrifugal pumps– less erosion, turbulence, longer seal life, reduced shaft deflection
• Handles high temperatures to 325° F.
• Compact design features including heavyduty drive shaft, adjustable bearing supports, and large capacity oil bath ensure low maintenance, durable performance for the toughest fluid applications
• Back pull-out design for easy servicing |

| Stancor' s duplex angular contact thrust bearings in the rear withstand far greater radial and axial thrust than conventional bearings. |
| External adjustment of rear bearing housing is
used to set impeller clearance ensuring zero end
play for maximum mechanical seal life. |
| Optimized shaft design features maximum
diameter-to-length ratio, minimal overhang, and
extra heavy-duty support to minimize shaft
deflection and associated seal wear. |
| Oil bath reservoir with overflow sight glass
keeps bearings fully lubricated. |

| Materials of Construction |
Kynar 370, a carbon filled PVDF material
is thermally stable to maintain tight dimensions.
For severe corrosives or high temperatures, solid
glass filled TFE PTFE is also available. |
Molded from solid Kynar 370 or TFE PTFE, Stancor semi-open tapered impellers are machined to the exact diameter required to control performance.
Additional back pump out vanes produce low stuffing
box pressures and keep seal area clear of debris. |
| Stancor pumps have a concentric casing (see illustration at right), which greatly reduces turbulence and vibration, extends seal and bearing life, eliminates excessive hydraulic imbalances and allows the pump to run anywhere between a FEW GPM to maximum flow without undue shaft deflection. The design allows the Stancor pump to handle abrasives much better than standard open impeller centrifugal pumps. |
