submersible pump with hazardous location motor end - Pump Express

PumpOperations9. Repeat this operation cyclesev er al times before leaving job.10.Check voltage when pumps areoperating, and check theamp draw of each pump.Check amps on each wireas sometimes a high legwill exist. One leg can besome what higher by 5 to 10per cent without causing trouble.For excessive amp draw onone leg, the electric utilitycompany should be consulted.PumpMaintenanceAs the motors are oil filled, nolubrication or other main te nanceis re quired.If the heat sensor and seal failureare hooked up properly, noattention is necessary as longas the seal failure indicatorlight doesn’t come on. To ensurecontinuity of the seal sensorleads, a test light is provided onin trin si cal ly safe Hydromaticpanels as standard equipment.Pump should be checked everyquar ter for cor ro sion and wear.Servicing instructions:iMPOrTANT: read alldirections before replacingany parts.WArNiNg: Before handlingthese pumps and controls,always dis con nect the pow erfirst.Do not smoke or use sparkableelec tri cal devices or flames in aseptic (gaseous) or possibleseptic sump.Field Service on HydromaticHazardous Location Pumps:If a Hydromatic hazardouslocation pump is used in ahazardous location the pump mustbe returned to the factory forservice. This will ensure theintegrity of the hazardous locationrating of the pump and com plywith our warranty re quire ments.Pumps out of warranty and notused in a hazardous location canbe field serviced by any reputableserviceman. When any fieldservicing is per formed on a pump,the fol low ing in struc tions shouldbe followed care ful ly.Disconnecting Pump Cords:If a Hydromatic hazardouslocation pump is to be removedfrom its loca tion, one of two waysmay be used to disconnect thepump cords from the rest of thesystem.Pump cords may be disconnectedat control panel (on sump mountedcon trol panels) and cord as sem blytaken with pump.CAUTiON: if cord openingsfrom sump to con trol panel areopen, gas es from sump couldenter panel and an explosivecondition could ex ist.Pump cords may be disconnectedat pump by removing the cord andcap assembly, unplugging sensorwires, and re mov ing wire nuts.After removal from pump,reinstall wire nuts in cord and capassembly and install protectivecover. (Hydromatic Kit 11456-000-1)CAUTiON: Do not reconnectpow er to a cord and cap assemblywhile removing from pump.replacing Cords:The power cord and heat sensor - sealfailure cord is potted into thecon nec tion box cap, forming thecord and cap assembly.If cords require replacement dueto damage or cords being tooshort, cord and cap assembly mustbe replaced as a complete assemblyavail able from factory.1. Remove cord and cap assemblyfrom con nec tion box.2. Disconnect wires taking noteof color/num ber coding.3. Connect wires of new cord andcap as sem bly in same manneras the old one was removed.4. Check for moisture and dryout.5. Reinstall cord and cap assemblyon con nec tion box taking carenot to pinch wires.6. Check pump for properrotation before re turn ing tonormal service.replacing Stator:If motor winding is burned orshorted, it can be rewound orreplaced with new factory woundsta tor. Refer to sectional drawingof pump and motor, and use thefollowing steps to remove andreplace stator.1. If only the stator is damaged, itmay not be necessary tocom plete ly dismantle pump asstator and housing can be liftedfrom pump without dis turb ingseals or bearings.5
