Saylor-Beall 707 Compressor Pumps

Saylor-Beall 707 Series Replacement Pump (7.5 – 10 HP)

The Saylor-Beall 707 is an industrial-grade, two-stage compressor pump built for maximum air delivery and extreme longevity. At this power level, heat management and structural integrity are critical; the 707 addresses these with a massive cast-iron frame and an oversized flywheel. It is designed to run at lower speeds than competing pumps in the 10 HP class, which significantly reduces wear and operating temperature.

Available Lubrication Configurations

1. Standard Splash Lubrication (Model 707) The industry standard for high-output, intermittent duty.

• Mechanism: Engineered dippers on the connecting rods create a high-velocity oil bath within the crankcase. This ensures that even during high-demand cycles, the cylinder walls and bearings are thoroughly coated.
• Benefit: Reliable and easy to maintain. It provides an excellent balance of performance and value for shops with standard duty cycles (e.g., large collision centers or woodshops).

2. Pressure Lubricated (Model 707-PL / L-Series) The ultimate configuration for continuous, multi-shift industrial environments.

• Mechanism: Features a crankshaft-driven gear pump that provides positive oil flow through rifle-drilled passages. This ensures that oil reaches the top-end components and wrist pins under constant pressure, regardless of load.
• Benefit: Extends the life of the pump in 24/7 operations. The pressure-fed system includes an external oil filter and a dedicated oil pressure gauge, allowing maintenance teams to monitor the health of the internal lubrication system at a glance.

Engineered for the Long Haul:

• Oversized Intercooler: A heavy-duty, finned copper intercooler is positioned to take full advantage of the flywheel’s airflow, stripping heat from the air before it reaches the second stage.
• Balanced Crankshaft: The drop-forged, precision-ground crankshaft is balanced to eliminate vibration, protecting your tank welds and nearby equipment.
• Swedish Steel Valves: Large-diameter disc valves made from high-grade Swedish steel provide high volumetric efficiency and resistance to carbon buildup.
