Saylor-Beall 20 HP Pressure-Lubricated Duplex Air Compressor

Saylor-Beall 20 HP Pressure-Lubricated Duplex Air Compressor (Model 9000)

The 20 HP duplex is the heavy-hitter of the Saylor-Beall reciprocating line. It features two 20 HP motors and two Model 9000 pumps mounted on a high-capacity horizontal tank (usually 240 gallons). This configuration is engineered for large-scale industrial plants where massive, reliable airflow is non-negotiable.

The Model 9000 Pump Advantage

The 9000 is a four-cylinder, two-stage V-type pump. At 20 HP, it provides a level of performance that smaller pumps simply cannot match.

• Massive Displacement: In this 20 HP configuration, each pump delivers approximately 67.4 CFM @ 175 PSI. When both pumps are running simultaneously, the system provides a staggering 134.8 CFM.
• Low-Speed Reliability: The 9000 pump is designed for high-horsepower applications. Even at 20 HP, it runs at a relatively low 640 RPM, which minimizes heat buildup and significantly extends the life of the internal valves and bearings.
• Smooth Operation: The V-4 design is inherently balanced, leading to less vibration and noise compared to large two-cylinder pumps pushed to their limits.

Lubrication Configurations

• Splash-Lubricated: The standard version for reliable, stationary industrial use. It uses a dependable dipper-style system to coat internal components in oil.
• Pressure-Lubricated (PL-9000): This is the premium choice for 20 HP units. It features a positive displacement oil pump and a spin-on oil filter. Forced lubrication ensures that even under the heaviest continuous loads, the crankshaft and connecting rods receive a constant stream of clean, filtered oil.

Technical Specifications (20 HP Duplex)

Summary

The 20 HP duplex with the 9000 pump is the definitive solution for facilities requiring 130+ CFM. By pairing the 20 HP motors with the oversized 9000 pump series, Saylor-Beall ensures that the system operates well within its mechanical limits, providing a service life that often spans decades.
