Design Benefits

• Solid Kynar* pump head for chemical compatibility and excellent abrasion resistance\
•  Concentric casing design for better flow patterns than other centrifugal pumps– less turbulence, longer seal life, reduced shaft deflection
• Handles high temperatures up to 250˚F
• Compact design features including heavy-duty drive shaft, adjustable bearing supports, and large-capacity oil bath to ensure low maintenance and durable performance for the toughest fluid applications
• Back pull-out design for easy servicing
• Handles solid sizes up to 9/16” maximum

Stan-Cor Patented Concentric Casing Advantages

Unlike volute-type centrifugal pumps, the Stan-Cor pump uses a unique concentric design that provides a constant, equal distance between the pump casing and the impeller at all times during pump operation. This greatly reduces turbulence and vibration, thereby extending the life of the mechanical seal and bearings.

In a conventional volute casing pump, water turbulence and eddies are created as the impeller passes the
restrictive cut water area in the casing. These hydraulic imbalances in turn cause the drive shaft to deflect, which increases the loading on the bearings, and leads to premature mechanical seal failure. At near shut-off, the bearing loading is extremely high.

The Stan-Cor concentric casing design eliminates these excessive hydraulic imbalances. It allows the pump to run anywhere between a few gallons per minute and full flow without undue shaft deflection. Moreover, the design allows the Stan-Cor pump to handle abrasives much better than standard models.

The sharp, restrictive cut water area of most pumps is the focal point for corrosion and erosion. It is the place where abrasives first attack a pump. With lined pumps, the thin liner is easily abraded away and the metallic backing exposed to the corrosive and abrasive forces of the product being pumped. The Stan-Cor concentric casing design, coupled with its solid homogenous non-metallic component, eliminates this problem area.
