*Note: Capacities are based on operating pressures up to 1500 psig. Derate flow 0.5% for each 100 psig over 1500 psig.
**Note: Motor horsepower is based on maximum flow rate at 1500 psig discharge pressure. For pressures above 1500 psig or flows lower than the maximum, consult the factory for horsepower required.

*Note: Max Pressure and Max Flow represent capacity at maximum backpressure.
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. Higher viscosity fluids will reduce capacity.
