In this regard how many amps does a 12 HP well pump draw. You need to know this for two reasons.

Various Ways To Determine Pump Flow In The Field Pumps Systems

The POR for this pump stretches from approximately 750 GPM to 1290 GPM which is 70 to 120 of 1075 GPM.

. I can think of three reasons you would draw more than rated full-load amps. Is there anything I can do so. But when voltage drops too low or as well see in a moment gets too high amps and current draw can spike.

Megged the stator and it checked out good. This is a common pump style for well pumps and it is often 240 volts and 1 HP. Bad pump motor starting.

A bad impeller can jam the pump causing it to draw high current. Stator is 9 wire. It is best to select a pump that will operate most of the time in the POR.

Try restricting the discharge valve until the amps come into the normal range. Measure amp draw on each leg 4. What Happens if the Amps are Too High.

Reason one is that the pump is running at a higher flow rate and lower pressure than it was. When amps get too high. Measure incoming voltage with pumps off and with pumps running 3.

1 The pump could be pumping much more water than the motor was sized for. 6-63 and 7-524 in NFPA 20 allow automatic sequencing of more than one fire pump to compensate for high inrush current due to starting and accelerating the load. A pump powered by an electric motor for the transfer or removal of natural or artificial pretreated liquid waste discharge from an onsite sewage treatment device or system.

Replaced seals and bearings. Thats what it should be drawing while. Should be drawing 7 amps per leg per mfg specs.

12 hp well pump The 12 HP motor under full load may go as high as 124 Amps unless the. 10 amps at 120V is pretty much a full horsepower around 60 efficiency or so. With a 10A no-load draw on 120VAC it aint the pump.

Remegged stator again and it is good. 2 The voltage at the. Count wash pump nozzles.

One is so you can know what size breaker is needed at the. This means that it will draw 10 amps of current but when started it might draw as much as 35. A 1HP submersible pump can draw electricity of 32 amperes at a single-phase motor and for a 3phase motor it will take 440 volts where 1phase motor is supposed to take 230 volts.

Amperage is the amount of electricity that runs through the electric wires. I know that the motor will draw high amps at start up but the high amps stays high for about 8 to 10 seconds. Remove obstruction in impeller housing inspect for and replace damaged impeller or frozen motor.

The pump and motor are in a pit with an air bladder. Read and report motor nameplate data HP FLA. Pump was brought to us not working.

Because this motor draws too high of amps we can only. This motor is on a circulating water system in a power plant. Now unit is drawing 30 amps per phase.

There are 3 motors and pumps that should run in parallel. 460V 3 phase submersible pump.
