Saylor-Beall 25 HP Pressure-Lubricated Duplex Air Compressor

Saylor-Beall 25 HP Pressure-Lubricated Duplex Air Compressor

The 25 HP duplex represents the heavy-duty peak of Saylor-Beall’s reciprocating line. Equipped with two 25 HP motors and two Model 9000 pumps, this system is typically mounted on a 240-gallon horizontal tank. It is engineered for facilities where air demand is constant and downtime is not an option.

The Model 9000 Performance at 25 HP

The 9000 is a four-cylinder, two-stage V-type pump. While it is used on the 20 HP units, the 25 HP configuration pushes the displacement to its maximum industrial rating.

• Maximum Airflow: At 25 HP, each pump delivers approximately 82.3 CFM @ 175 PSI. In a duplex configuration, with both pumps running, the system provides a massive 164.6 CFM.
• Optimized Industrial Speed: To achieve this output, the pumps run at 780 RPM. While faster than the 20 HP version, this remains significantly slower than most industrial competitors, ensuring the cast-iron components stay within safe thermal limits.
• Balanced V-4 Design: The four-cylinder layout ensures smooth operation and superior heat dissipation, which is critical at the 25 HP power level where friction and heat are at their highest.

Lubrication & Protection

• Splash-Lubricated: A dependable, time-tested system suitable for standard industrial applications.
• Pressure-Lubricated (PL-9000): Highly recommended for the 25 HP duplex. At this level of investment and workload, the positive displacement oil pump and spin-on oil filter provide essential protection. Forced lubrication ensures that clean oil reaches the crankshaft and rod bearings instantly, even under 24/7 continuous loads.

Technical Specifications (25 HP Duplex)

Summary

The 25 HP duplex with the 9000 pump is the “big brother” of the reciprocating world. It is the ideal choice for massive industrial operations that need 160+ CFM but prefer the serviceability and longevity of a reciprocating pump over a rotary screw compressor.
