Drops per Stroke Table Section of Table Applies to Suction and Gravity Fed Models Only
• Allowable viscosity range independent of temperature: 80-5000 SUS.
• Strokes/Minute - Maximum - 50; Minimum - 3
• Stroke Length - Maximum 1/2 inch (12.7 mm)
† Refer to your manufacturer’s specific instruction manuals to ensure your box and lubrication system are rated for
the selected pressure.
1 Based on 500 SUS oil at 70°F ambient. Heavier oil will produce fewer but larger drops.
2When approaching maximum outputs, some oils will stream rather than form drops in sight glass.
