Mazzei - ISO 1587 Series - 40mm Male BSPT Inlet/Outlet Connections (0.50" Barbed/Male NPT Threaded Suction Port Cap)
ISO 1587 Series 40mm Male BSPT Chemical Injector
Differential pressure injector with internal mixing vanes for efficient chemical and air injection in water treatment systems. 40mm male BSPT inlet and outlet connections with 0.50" barbed or male NPT threaded suction port cap.
Venturi-Driven Chemical Injection Technology
Pressure Differential Injection
Pressurized water is constricted through the injection chamber, creating a high-velocity jet stream that generates vacuum at the suction port to draw in liquid or gas additives.
Internal Mixing Vanes
Patented internal vanes create thousands of microbubbles, dramatically increasing surface area contact between gas and liquid for superior solubility and mixing efficiency.
No Moving Parts
Zero mechanical components means simplified maintenance and lower operating costs compared to mechanical injection systems with pumps or motors.
Wide Pressure Range
Operates effectively across a broad range of inlet pressures with minimal pressure differential required between inlet and outlet to initiate suction.
Available Injector Body Materials
Polypropylene (GRPP)
Green polymer with high tensile strength, resistant to most acids and alkalis. Lightweight, rigid, and cost-effective for general water treatment applications.
PVDF (Blue or Natural)
Advanced thermoplastic superior to PVC and PP. Handles higher pressures and temperatures, resists ozone, sulfuric and nitric acids, chlorine, and UV light. NSF 61 and FDA approved in natural form.
ECTFE
High-performance fluoropolymer with extreme chemical resistance in alkaline conditions above pH 10. Low flammability, excellent weather resistance, and insensitive to UV-A and UV-B light.

BSPT Thread Sizing Reference
British Standard Pipe Thread (BSPT) does not measure as its fractional name suggests. A 40mm BSPT thread will measure larger than 40mm when measured with a ruler. BSPT sizing refers to the nominal bore, not the actual outer diameter of the threaded connection. When selecting mating fittings or adapters, always specify BSPT thread standard rather than measuring with calipers. Note that 0.5" Male NPT PVDF injectors are interchangeable with 15mm Male BSPT PVDF injectors as they share the same threads per inch.
Chemical and Gas Injection Use Cases
The Mazzei ISO 1587 venturi injector is ideal for introducing chemicals, fertilizers, disinfectants, and gases into water systems. Common applications include agricultural fertigation, municipal water treatment chlorination, aquaculture oxygenation, industrial process chemical dosing, pool and spa sanitizer injection, and ozone contact systems. The 40mm BSPT connections accommodate commercial and industrial flow rates where precise chemical metering and thorough mixing are required without the complexity of mechanical injection pumps.
Zero Maintenance
No pumps, motors, or moving parts to service or replace
Low Operating Cost
Uses existing water pressure with minimal energy loss
Superior Mixing
Microbubble generation maximizes gas-liquid contact area
Durable Materials
Chemical-resistant polymers for long service life
