Our recommendation is to change our motor starters/single phase components over <br />to VFD inverters, which allows us to supply three phase power to the s!.lbmersible pumps from the <br />existing single phase power supply, currently the existing pumps are single phase only and wO!.lld <br />req!.lire a costly rewind of the motors. It would be the most effective If changed om the pumps with <br />new!.Inits, we would be able to use the existing discharge piping and guide system. Our quotation is as <br />follows; <br /> <br />Lift Station III <br /> <br />(2) m lGA71H3CD Submersible Grinder p!.lmps, 3hp, 230j3phj60hz, Including 35' of power <br />cord, Installation of existing slide bracket, chain, wired into control panel, and start !.Ip. <br /> <br />(2) AC Tech ESV552N02TXB VFD power inverters designed for 230jlph inp!.lt to 230j3ph outP!.lt <br />specifically for Shp motors, with jog reference.
