PF Series High—Head Effluent Pumps <br /> Materials of Construction <br /> Discharge: Glass-filled polypropylene or stainless steel <br /> Discharge bearing: Engineered thermoplastic(PEEK) <br /> Diffusers: Glass-filled PPO(Noryl GFN3) <br /> Impellers: Celcon"acetal copolymer on 10-,20,and 30-gpm models;50-gpm impellers are Noryl GFN3 <br /> Intake screen: Polypropylene <br /> Suction connection: Stainless steel <br /> Drive shaft: 7/16 inch hexagonal stainless steel,300 series <br /> Coupling: Sintered stainless steel,300 series <br /> Shell: Stainless steel,300 series <br /> Motor: Franklin motor exterior constructed of stainless steel.Motor filled with deionized water and propylene glycol for constant <br /> lubrication.Hermetically sealed motor housing ensures moisture-free windings.All thrust absorbed by Kingsbury-type thrust <br /> bearing.Rated for continuous duty.Single-phase motors and 200 and 230 V 3-phase motors equipped with surge arrestors for <br /> added security.Single-phase motors through 1.5 hp(1.11 kW)have built-in thermal overload protection,which trips at <br /> 203-221'F(95-105'C). <br /> Using a Pump Curve <br /> A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow(gpm or L/sec)and <br /> pressure(total dynamic head,or TDH),providing a graphical representation of a pump's optimal performance range.Pumps perform <br /> best at their nominal flow rate—the value,measured in gpm,expressed by the first two numerals in an Orenco pump nomenclature. <br /> The graphs in this section show optimal pump operation ranges with a solid line.Flow flow rates outside of these ranges are shown with <br /> a dashed line.For most accurate pump specification,use Orenco's PumpSelect'"software. <br /> Pump Curves, 60 Hz Models <br /> 800 160 <br /> PF10 Series,60 Hz,0.5-2.0 hp — PF15 Series,60 Hz,0.3 hp - <br /> 700 PF1020 140 <br /> as m <br /> w <br /> 600 a 120 PF1503 <br /> 500 100 <br /> Q400 PF1010 = 80 <br /> � <br /> 30041 � 60 <br /> �&&07 <br /> e <br /> a a <br /> 200 40 <br /> w <br /> r° PF1005-FC t° <br /> 100 w/'/a"flow 20 <br /> controller <br /> 0 <br /> 0 2 4 6 8 10 12 14 16 0 3 6 9 12 15 18 21 24 <br /> Flow in gallons per minute(gpm) Flow in gallons per minute (gpm) <br /> NTD-PU-PF-1 ©2012 Orenco Systems'Inc. <br /> Rev.2.0,©01/12 <br /> Page 4 of 6 <br />
