STEAM PRESSURES--PSIG
Cpacities in Gallons per Hour with 12 PSIG
Water Pressure Supply at 74°F Temperature
Capacities shown are maximum amount injector can pump
at steam pressures indicated. If flow exceeds amounts
shown, due t o excessive water supply pressure, valve in
water supply line can be regulated to provide correct flow.
Capacities are redu ced if injectors are required to handle
water at higher than normal temperature. When operating
with a 3 f t lift at the limiting temperature, for a given steam
pressure, capacities are reduced approximately as follows:
Water Temperature
90°F 100°F 110°F 120°F
