Priming and Air Separation Integrated within the Casing

• • The dual volute configuration facilitates efficient suction priming with a minimal initial liquid charge retained within the casing.
  • During priming, the lower volute acts as the intake path, while the upper volute channels the liquid-air mixture into a dedicated separation chamber.
  • Entrained air is segregated and expelled, while liquid is recirculated to sustain the priming cycle.
  • Once all air is removed, the pump transitions to normal centrifugal operation, with both volutes functioning for stable discharge.
  • The casing's built-in liquid retention ensures dependable automatic re-priming, even after backflow events.

Consistent Self-Priming Performance

• • Efficient air evacuation is mandatory for non-submerged, negative suction applications.
  • The A796's integrated priming chamber retains ample liquid for reliable automatic re-priming without external systems.
  • All priming and air separation occurs within the one-piece casing chamber—no auxiliary equipment needed, enhancing system simplicity and operational reliability.

Dynamic Sealing

• • Ideal for corrosive and slurry handling—no mechanical seal required.
  • Eliminates the need for seal cooling water and reduces utility costs.
  • Economical and robust alternative to specialty slurry seals.

High Temperature Application

• • Finned Cooler: Directly cools oil for lower bearing temperature. Requires minimal cooling water.

    

  • Corrosion-resistant construction recommended for use above 350°F (177°C).
  • Jacketed Stuffing Box: Maintains proper temperature in the sealing environment; ideal for polymerizing or temperature-sensitive fluids.

Ease of Maintenance

• • Back Pull-Out Design: Remove rotating assembly without disturbing piping or motor for reduced maintenance time and minimum downtime.
  • Interchangeable Parts with A196: Core components are dimensionally standardized and interchangeable with A196 pumps for simplified spares and servicing.
  • External Impeller Adjustment: Allows clearance adjustment externally to optimize efficiency and extend component life.
  • Easy Retrofit: Simple drop-in replacement for upgrades and installations.

Safety

• • ANSI B15.1 Coupling Guard: Protects personnel from moving parts, fully compliant with safety regulations.
  • High-Strength Ductile Iron Mounting Adapter: Exceptional durability under mechanical and thermal stresses.
  • Precision-Machined Serrated Flanges: Enhance gasket grip and sealing reliability, reducing leakage risks under varying conditions.
