The Self-Priming Adaptor (SPA) provides fast self-priming for all standard centrifugal pumps. The Self-Priming Adaptor is available in a 2” NPT size.

• Creates self-priming capability for all standard centrifugal pump models
• Increases priming efficiency over open impeller transferpumps and self-priming centrifugal pumps
• Allows the use of a single, high efficiency pump for both tank filling and spraying
• Constructed out of 304 stainless steel for corrosion resistance
• Protects the pump’s mechanical seal from dry-run during priming operations for on-board loading
• Guards against unexpected dry-run conditions during spraying application, if system were to function automatically
• Allows centrifugal pumps to be mounted in tight-fitting configurations while maintaining priming and flow performance capabilities
• SPA can be mounted in nearby remote location up to 10 ft (3 m)from pump
