Electric PumpsIntroductionSimplex vs. Duplex Pump Operation:A Simplex System contains a single pump and receiver tank. Duplex Systems contain two pumps ona common receiver tank allowing the second pump to serve as a back up in case of failure.For Duplex Condensate Return Pumpsthe Float Switch is replaced with a MechanicalAlternator. The Mechanical Alternator isattached to a float and activates onlyone pump at a time in an alternating manner.The Mechanical Alternator switches powerbetween the two motors so that the runtime ofeach pump is shared, allowing the system tocontinue operation in the event of a singlepump al Alternator/Float Switch(must be ordered separately with Duplex units)Motors & ControlsSingle-Phase motorsSingle-phase motors supplied with these pumps haveoverload protection and therefore do not require ancillarymotors starters. Single-phase motors can be wired directlyto the Float Switch (for Simplex units) or the MechanicalAlternator (on Duplex units) and no control panel isrequired for installation.3-Phase motors3-Phase motors do not have overload protection andtherefore require a separate Motor Starter to operate.A Motor Starter contains a set of Electrical Contactorswith overload protection (OL) to protect the motor. Thestandard Float Switch or Mechanical Alternator/FloatSwitch is wired to the Motor Starter and closes theContactors to start the pump. The OL device incorporatedinto the Motor Starter protects the motor from damage.A separate circuit breaker or fuse box is still required toprotect the circuitry.TypicalMotor StarterNEMA-12 Control PanelFor Simplex units, the control panel would include asingle motor starter with a single HOA (Hand-OffAutomatic) selector switch to turn the pump on manuallyto verify functionality; or, to set in automatic mode alongwith a single Motor Circuit Protector switch to shut poweroff to the pump in case of overload. The purpose of theMotor Circuit Protector is to protect the wiring to thepump eliminating the need for a separate circuit breakeror fuse box.For Duplex systems, the control panel would include twomotor starters, two HOA Switches and two MotorCircuit Protector switches.NEMA-12Control PanelSimplex Unitshown withControl PanelDuplex Unitshown withControl PanelTel: 610-495-5131 Pottstown PA USA www.watsonmcdaniel.com171

Electric PumpsIntroductionELECTRICPUMPSOperation of CONDENSATE RETURN PumpsCondensate Return Pumps are designed to operate intermittently, discharging condensate only when the receivertank is full. This is accomplished with a float switch that energizes the pump when the float rises above a set point.Once started, the pump will continue to operate until the water level drops below the bottom set position of the floatswitch. On Duplex condensate return pumps, a Mechanical Alternator float switch is mounted to the receiver sothat both pumps are used in an alternating manner.Simplex UnitDuplex UnitReceiverTankReceiverTankSecondaryPump & MotorFloatSwitchSinglePump & MotorMechanicalAlternatorCondensate Return Pump Piping DiagramVent:Pipe up toceiling, thenback down tofloor draincondensatereturn inletflowventedreceiverReturnscondensateback to boilerfeed evalvedischargecondensate by-passclean out(pipe to floor drain)checkvalvefloor lineFloat Switch for Simplexunit or MechanicalAlternator Float Switchfor Duplex unit174www.watsonmcdaniel.com Pottstown PA USA Tel: 610-495-5131
Electric PumpsIntroductionOperation of BOILER FEED PumpsELECTRICPUMPSFor Boiler Feed applications, the operation of the pump is controlled by the water level control system onthe boiler. When the boiler requires water, the pump switches on pumping water from the receiver into theboiler. The receiver tank also contains an internal make-up water valve actuated by a stainless steel float.If the amount of condensate being returned to the receiver tank is inadequate to supply the boiler, additionalmake-up water is added to the receiver tank. This condition may occur when more steam is being producedthan condensate being returned; common at system start-up.An overflow pipe is used to dump excess condensate to drain during times when less boiler feed water isrequired than the amount of condensate being returned. Larger boiler feed tanks may be advantageous tokeep systems in balance.Duplex Boiler Feed UnitReceiverTankSecondaryPump & MotorGaugeGlassWater Make-upValveBoiler Feed Pump Piping DiagramWATER LEVEL CONTROL SYSTEM:Controls Pump OperationWater level control system on boilermay contain a float mechanism orset of sensors to maintain properwater level in the boiler.wall mountedcontrol r& pumpcondensatereturn inletpump discharge linecold watersupplyBOILERCheck Valve:required to prevent boilerwater returning to reservoirwhen pump is off.Tel: 610-495-5131 Pottstown PA USA www.watsonmcdaniel.com175
Electric PumpsIntroductionWhat is required to choose and install an Electric Pump?ELECTRICPUMPSSelecting a Condensate Return Pump: A Condensate Return Pump contains an automaticfloat switch in the receiver tank to activate the pumpwhen the tank is filled and deactivate when empty. On Duplex units, the standard float switch is replacedwith a Mechanical Alternator float switch to alternateoperation between the two pumps. Must be orderedseparately. An Electric Alternator is also an option. The capacity of the condensate return pump in GallonsPer Minute (GPM) is based on the amount of EffectiveDirect Radiation (EDR) in sq ft. of heating surface in thefacility that the pump is expected to handle.Selecting a Boiler Feed Pump: For a Boiler Feed Pump, the operation of the pumpis controlled by the water level control system onthe boiler. When the boiler requires water, the pumpswitches on pumping water from the receiver into theboiler. The receiver tank also contains an internalmake-up water valve actuated by a stainless steelfloat. This is used if the amount of condensate beingreturned to the receiver tank is inadequate. On Duplex boiler feed pumps, an Electric Alternator isrequired to cycle operation between the two pumps. The capacity of the boiler feed pump in Gallons PerMinute (GPM) is based on the Boiler horsepower (hp).For Example: an EDR of 2000 sq. ft. can condenseup to 500 lbs/hr of steam which translates to 1.0 GPMof condensate flow. Using a 3:1 safety factor wouldrequire a 3.0 GPM Condensate Return pump. Theproperly sized receiver tank that is adequate for thatpump capacity is shown in the model selection chart forCondensate Return units. Larger receiver sizes arealways desireable in order to cool condensate. Select a discharge pressure for the pump to overcomeall system back pressures including frictional pipinglosses. Pump discharge pressures of 20-50 PSI areavailable. Selecting a pump with a significantly higherdischarge pressure than required can cause pumpto cavitate.For Example: A 15 horsepower boiler will produceup to 500 lbs/hr of steam when running at maximumload which translates to requiring 1.0 GPM of watermake-up to the boiler. Using a 3:1 safety factor wouldrequire a 3.0 GPM Boiler Feed pump. The recommended receiver sizes based on boiler horsepower areshown in selection chart. Select a discharge pressure for the pump to overcomeboiler pressure and all system back pressure includingfrictional piping losses. Pump discharge pressures of20-50 PSI are available.General Information:Applies to both Condensate Return & Boiler Feed Pumps1) Select the model with the appropriate sized receiver and pump discharge pressure. 4100-Series Carbon Steel tank,4200-Series – Cast Iron tank or 4300-Series – Stainless Steel tank.Safety factors and proper operating conditions: Pumps have a 3:1 safety factor. The 3:1 safety factor for CondensateReturn pumps is based on the maximum condensate that can be produced by the EDR (Effective Direct Radiation) insquare feet. For Boiler Feed pumps, the 3:1 safety factor is based on the maximum amount of water that would berequired by the boiler (based on Boiler hp). Therefore, when the system is operating at maximum capacity, the pumpwill operate only one third of the time. Please note: these pumps as configured are not recommended for pumpingcondensate above 190 F.2) Motor hp required for any given pump model is listed in the selection chart. For motor sizes below 1 hp, it is mostcommon to choose single phase motors; (1Ph either 110 or 220 Volts). Single-phase motors (available up to 2 hp)have inherent overload protection (OL) and can therefore be wired directly to the float switch or Mechanical Alternator.This is the simplest method of control and does not require any additional electrical hardware. Since 3-Phase motorsdo not have inherent OL protection, they require a separate Motor Starter. Motor starters can be purchased separatelyfrom an electrical supply house or ordered separately with pump unit. Reference our NEMA 1 or NEMA 12 ControlPanels with Motor Starter.3) Duplex pump units require the addition of a mechanical or electrical Alternator which activates one pump at a timein alternating fashion. Condensate Return pumps most commonly use a Mechanical Alternator in place of the standardfloat switch and must be ordered separately. Refer to Model MECH-ALT-N1. For duplex Boiler Feed pumps, theElectric Alternator option on the NEMA-12 Control Panel (suffix code E) must be chosen. An Electric Alternatorcan also be used with Condensate Return pumps; however, an additional 2-level float switch is required(2-level float switch is Not required on boiler feed units).176www.watsonmcdaniel.com Pottstown PA USA Tel: 610-495-5131

When the float rises aboveits set point, it energizes the motor on the pump. Once started,the pump will continue to run until the water level drops belowthe bottom position of the float switch.There it will de-energizethe motor to shut off the pump. This cycle repeats as condensatebegins to fill the receiver tank. On duplex systems the float switchis replaced with a Mechanical Alternator-Switch connected toa float. The Mechanical Alternator cycles use between the twopumps, allowing only one pump to run at a time under normalconditions. If the condensate reaches a high water level, bothpumps will be activated.

W4100, W4200 & W4300Electric Condensate PumpsElectric PumpHow to Order an Electric Condensate Return or Boiler Feed PumpOrdering Guidelines:ELECTRICPUMPS1) Decide on appropriate Receiver tank material for the application; W4100-Series with Steel Receiver tanks, W4200-Serieswith Cast Iron Receiver tanks or W4300 with Stainless Steel Receiver tanks.2) Based on the particular application the model selection charts are separated on adjoining pages into either Boiler Feed orCondensate Return units. The proper pump model/size in GPM (gallons per minute) to suit the application and recommended receiversize for a Boiler Feed application is based on boiler size measured in Boiler Horsepower. The proper pump model size in GPM andrecommended receiver size for a Condensate Return application is based on the Effective Direct Radiation (EDR) in square feet of theheating surfaces throughout the facility that the pump is expected to handle.3) Select a pump discharge pressure that will exceed system back pressure, friction loss in piping and pressure in the boiler (in the caseof a boiler feed pump). Selecting a pump with a significantly higher discharge pressure than required can cause pump to cavitate.4) Decide if a Simplex (Single pump) unit is adequate or a Duplex (two pump) unit would be more appropriate in terms of systemreliability and redundancy in the event of a pump failure.5) Select Motor Phase and Voltage (reference chart). For smaller units under 11/2 hp Single phase motors may be desirable becauseof ease of installation. For units in excess of 11/2 hp, the more efficient and robust 3-phase motors are recommended.Example Model Code: W4142JD-3P230Duplex Condensate Return Pump, 3 GPM flow rate & 40 PSI dischargepressure & 15 gallon receiver, 1hp, 230 VAC, 60Hz, 3-Phase motor.(Pump Unit)Example Model Code: MECH-ALT-N1Note: Since a Duplex pump was chosen, a Mechanical Alternator must be purchasedseparately to replace the standard Float Switch.(Mechanical Alternator)Condensate ReturnBoiler FeedFloat Switch(standard withSimplex units)NEMA-12Control Panel(optional)NEMA-12Control Panel(optional)Gate Valve,Check Valve &Pressure Gauge(optional)Isolation ional oncondensatereturn units)MechanicalAlternatorPhase & Voltage Codes for Standard 60/50 Hz MotorsMotor Phase & VoltageSinglePhaseThreePhase178115 VAC208 VAC230 VAC208 VAC230 VAC460 VAC575 VAC60 Hz MotorCode1P1151P2081P2303P2083P2303P4603P575Gauge Glass(standard onBoiler Feed Pumps)(must be orderedseparately withDuplex units)50 Hz ECodes for Specialty Motors (add as a Suffix)OptionTotally Enclosed Fan Cooled (1/2 to 3 hp)Explosion Proof – 1/2, 3/4, 1 hpExplosion Proof – 11/2 & 2 hpExplosion Proof – 3 hpwww.watsonmcdaniel.com Pottstown PA USA Tel: 610-495-5131Suffix CodeTEFCEP1EP2EP3WaterMake-UpValve
