Mazzei (SPSA-2-A) Suction Port Screen w- Check Valve - 2" FNPT Connection
SPSA-2-A Suction Port Screen Assembly with Integrated Check Valve
2" FNPT threaded screen assembly engineered to protect chemical injectors from debris and backflow in municipal and agricultural water systems
The Mazzei SPSA-2-A is a critical filtration component designed for use with 2" Mazzei chemical and air injectors. The integrated screen filters particulate before it enters the injector suction port, while the built-in check valve prevents reverse flow when the system shuts down. Essential protection for maintaining injector performance in fertilizer injection, chlorination, and ozone systems.
Engineered Protection for Venturi Injectors
2" FNPT Threaded Connection
Standard female NPT threads for direct installation on 2" Mazzei injector suction ports and chemical supply lines
Suction Port Screen
Filters debris and particulate from chemical feed lines before entering the injector, preventing nozzle clogs and performance loss
Integrated Check Valve
Prevents backflow of motive water into chemical supply tanks when the system cycles off or pressure drops
Mazzei OEM Component
Factory-engineered by Mazzei for compatibility with their venturi injector product line, ensuring proper fit and function
Chemical Resistant Construction
Built to handle common agricultural and municipal chemicals including chlorine, fertilizers, and oxidizers
Serviceable Design
Screen and check valve components can be accessed for cleaning or replacement to extend service life
Applications and System Integration
The SPSA-2-A is designed for use with Mazzei 2" venturi injectors including models in the 584, 684, and 884 series. Common applications include agricultural fertilizer injection systems, municipal water chlorination, wastewater treatment oxidation, greenhouse nutrient dosing, and irrigation chemical injection. Compatible with inline installation on PVC, polyethylene, and stainless steel piping systems. Recommended for all Mazzei 2" injector installations where chemical feed lines may contain suspended solids or where backflow prevention is required by code or system design.
Mazzei has been manufacturing venturi injectors and components since 1978, trusted by water treatment professionals worldwide for reliability in demanding chemical injection applications.
