Choosing the Right Airless Spray Pump (Single-Leg Pumps)
Choosing the Right Airless Spray Pump (Single Leg Pumps)
Choosing the right single-leg component sprayer is critical to achieving consistent coating application and jobsite productivity. The correct pump supports proper material flow, reliable spray pressure, and efficient operation without unnecessary interruptions. This guide walks through how to select the right single-leg component sprayer based on your application and job conditions.

Common Applications
Single-leg airless pumps are used in industrial and commercial coating environments where thick materials must be applied evenly:
Each application affects required pressure, material flow, and overall production rate.
Key Factors to Consider When Choosing the Right Equipment
The pressure ratio determines how much force is applied to move and atomize material. Lower ratios are suitable for moderately thick coatings, while higher ratios perform better with very high-viscosity or high-build materials. Choosing the correct ratio supports smooth spraying and consistent finish quality.
Different coatings place different demands on the pump. Thicker materials require higher pressure to spray properly, and improper pump selection can lead to poor atomization or inconsistent coverage. Material specifications should guide pump choice.
Larger jobs require steady, uninterrupted spraying, while smaller jobs may not require the highest output. Continuous, high-volume coating benefits from higher-capacity pumps. Matching pump capability to job size avoids inefficiencies.
Single-leg pumps are airless sprayers, meaning material is atomized by pressure rather than air. This produces consistent spray patterns and is well-suited for industrial coating applications. Proper setup and operator technique are important for best results.
Choosing the Right Pump for Your Job
When in doubt, always review the application section of the coating’s technical data sheet (TDS). Manufacturers typically specify recommended pump ratios and spray tip sizes, which can help confirm whether a 63:1 or 75:1 unit is appropriate for the material being applied.
Common Rental Scenarios & Recommendations
Confirm coating type and viscosity before selecting a pump.
Match pump ratio to material requirements.
Ensure adequate air supply for airless operation.
Plan for proper hose lengths and spray accessories.
Assign experienced operators for consistent results.
