Test data taken with water at 90° F. (31 SSU).
Pump performance when pump is new. As pump wears, the performance will decrease.
(*) Female NPT inlet and outlet (in inches). (**) Suction lift requires wetted gears and primed seal chamber.
NOTES: Max. PSI = 125 , Max. Viscosity = 500 SSU at 1725 RPM with standard spur gears, Max. RPM = 1725
Max. Specific Gravity = 1.1 at 125 PSI, up to 1.6 at lower PSI & viscosity. Max. Input Torque = See chart above.
Reverse Rotation = Pumps can be run in reverse rotation.
The pump relationship between volume (GPM), pressure (PSI), speed (RPM) and horsepower is shown on performance chart in Shurflo Motor Manual
form L-4082. When pumping a more viscous liquid, a slower speed, a larger pipe size pump, and possibly a larger motor should be selected.
Manufacturer reserves the right to change performance without notification.
