MV30018 Chemical Injector 1.8 mm | 4060 PSI Fixed Chem

MV30018 Fixed Chemical Injector Overview

The AR MV30018 fixed chemical injector is a precision-calibrated detergent mixing component engineered to deliver consistent and accurate chemical dosing for high-pressure cleaning systems. Featuring a 1.8 mm orifice and a pressure rating up to 4,060 PSI, it ensures reliable suction, steady flow, and uniform detergent application across diverse commercial and industrial wash environments.

This fixed-orifice design maintains a constant chemical-to-water ratio, eliminating the need for manual adjustments and supporting repeatable, dependable results.

MV30018 Key Features

• 1.8 mm fixed orifice for predictable injection ratio
• Rated for systems up to 4,060 PSI
• Venturi-driven suction for smooth chemical draw
• Corrosion-resistant brass body with stainless-steel internals
• Compatible with 2.5–5.5 GPM pressure washer systems
• Automatic activation with low-pressure spray tips
• Integrated check valve prevents backflow and contamination

Construction & Durability

Built from corrosion-resistant brass and equipped with stainless-steel internal components, the MV30018 is engineered to withstand continuous exposure to detergents, degreasers, and industrial cleaning chemicals. Its smooth internal pathways minimize turbulence and wear while maintaining long-term performance stability.

Durability Benefits

• Resists chemical corrosion, scaling, and oxidation
• Heavy-duty body reduces pressure loss
• Precision-machined components maintain long-term flow accuracy
• Low-maintenance design with no adjustable or moving parts

Performance & Operation

The injector uses the Venturi principle to create a controlled pressure drop that draws detergent into the water stream. This provides consistent mixing and a predictable detergent ratio without impacting system pressure stability.

Performance Advantages

• Consistent suction across varied operating conditions
• Stable chemical delivery for uniform cleaning results
• Reliable operation in both cold and hot water systems
• Supports longer hose runs and variable supply conditions

Installation & Compatibility

The MV30018 installs easily into the discharge line between the pump and spray gun or into a quick-connect assembly. Standardized fittings ensure compatibility with most professional-grade pressure washers, mobile rigs, and stationary systems.

Installation Highlights

• Compact design fits into tight system layouts
• Quick-connect compatible for fast integration
• Automatic soap/rinse switching based on nozzle pressure
• Backflow-preventing check valve protects chemical supply

Maintenance

Maintenance is simple: flushing clean water after each use prevents detergent residue buildup and keeps the injector functioning efficiently. Stainless-steel check valve components maintain reliable suction over extended service intervals.

Maintenance Tips

• Flush clear water through the system after each session
• Inspect suction barb and check valve periodically
• Use proper suction tubing and a clean detergent filter
• Clear suction port if suction weakens

MV30018 Applications

• Vehicle and fleet washing
• Construction and heavy equipment cleaning
• Agricultural facility sanitation
• Industrial wash bays
• Large-surface cleaning and sanitizing

Professional Advantages

The AR MV30018 offers fixed-ratio simplicity, robust construction, and dependable chemical dosing. It reduces chemical waste, enhances cleaning consistency, and delivers the reliability needed in demanding commercial environments.
