STANDARD PERFORMANCE TEST DATA FOR PUMP MODEL 4D-B
Based on 70_ F (21_ C) clear water at sea level
with minimum suction lift, using 3 inch (7,62 cm)
suction hose and 4 inch (10,16 cm) non-collapsible
discharge hose. Since pump installations are sel-
dom identical, your performance may be different
due to such factors as viscosity, specific gravity,
elevation, temperature, and impeller trim.
If your pump serial number is followed by an “N”,
your pump is
NOT a standard production model.
Contact the Gorman-Rupp Company to verify per-
formance or part numbers.
