	Delivery capacities shown are maximum amount injector can pump at steam pressures indicated. If flow exceeds amounts shown, due to excessive water supply pressure, vale in water supply line can be regulated to provide correct flow.

	Suction lifts to 20 feet are possible without excessive reduction in delivery (gph). Please request data


	Delivery capacities are reduced if injectors are required to handle water of higher than normal (74 degrees F) temperature. When operating with a 3 fi lift at the limiting temperature for a given steam pressure, capacities are reduced approximately as follows: Water temp: 90 F 100 F 110 F 120 F Capacity Reduction: 10% 12% 15% 20%
