    Note: Above capacities and suction lift refer to pumps tested on water at 115 VAC, 60 Hz, and an ambient temperature of 70 °F (20 °C). Higher specific gravity fluids will reduce suction lift. Capacities will be slightly reduced from published ratings if pumps are skid mounted)

    External pulse contact retrofit available as an option (P/N 1046731)

    NSF 50 certification only applies to NPB0 & NPB2 liquid ends
