P
erformance in water will decrease by about 10%, and HP required will also be reduced by 10%. (Don’t use water with Cast Iron.)
Pump performance when pump is new. As pump wears, the performance will decrease.
(*) NPT inlet and outlet (in inches).
(**) Suction lift requires wetted gears and primed seal chamber.

NOTES: Pumps with motors are HP rated to handle up to 500 SSU at 100 PSI and specific gravity of 1.0.
Max. PSI = 100
Max. Viscosity = 500 SSU
Max. RPM = 1725
Max. Specific Gravity = 1.1 at 100 PSI, up to 1.6 at lower PSI & viscosity.
Max. Input Torque = See chart above.
Reverse Rotation = Pumps are equipped with pressure relief valves and can be run in reverse rotation; however, pressure relief valve will not
function when pump is reversed unless pump relief valve cover is rotated 180°.
The pump relationship between volume (GPM), pressure (PSI), speed (RPM) and horsepower is shown on performance chart in Shertech 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.
