hi, according to my electrician i have a regular 110 line available for the pool pump, since i can't reach him right now and I'm shopping for pumps, I'm looking at a pentair superflo 1.5 hp, 2 speed, 230v, so i have to ask whats probably obvious my 110 will not cover the power needs of this pump? thanks
A shopper on Jan 17, 2016
BEST ANSWER: Enter aAlthough the motor is wired for 220, it can be wired for 120 if you need to run it at only one speed (either high or low) whenever it’s powered. I bought this motor so that I could run it at low speed for continual water circulation, filtration, and heating. The only time I run it at high speed is briefly for vacuuming, for which a lot of suction is required.

You could run it at high speed all the time with just a 120 circuit, but it’s overkill if you do and very noisy. High speed produces suction that’s dangerous if you’re not careful. It could literally rip the flesh from your hand if you put your hand over the end of the vacuum hose.

I wired mine myself, so I know how it’s wired. I dedicated a 20 amp, 220 Volt breaker to the motor. One hot lead from it powers the slow speed motor windings, and the other hot lead powers the high speed. A third lead, that’s common to both high and low, returns to neutral in the breaker box. To make it all work the way you want it to takes electrical expertise if you’re switching it remotely (as opposed to switching on the motor itself). I control mine from a switch box several feet away.

The motor is an extremely fine and rugged device. My last one lasted 17 years (24-7!) before it began to leak and couldn’t be repaired by changing the seals. My last one could be switched between high and low using a 120 breaker. But they no longer make that model. Note that with the new one you’re never drawing more than 110: the motor is never drawing 220. But to have both high and low alternately available, it must be a 220 circuit. There’s no way around it.
n answer to this question.
what is the motor Service Factor (SF)?
Mohammad A on Sep 23, 2015
BEST ANSWER: Enter an answer t1.15
This means that a 10-hp motor with a 1.15 SF could provide 11.5 hp when required for short-term use. Some fractional horsepower motors have higher service factors, such as 1.25, 1.35, and even 1.50. In general, it's not a good practice to size motors to operate continuously above rated load in the service factor area.o this question.
I have purchased a Pentair WhisperFlo 2-speed 1.5 HP 230V 60HZ motor. It works on high speed, but hums when switch to slow speed. I thought it is the capacitor problem, and replace with another one. It does the same thing. Any advice from anyone?
Chongjun J on Apr 11, 2020
BEST ANSWER: Does it still work but hums? Is the impeller moving water on low? Mine is very quiet on low and semi quiet on high. Wondering if the impeller might just stick when on low.
can switch on dual speed motor easily be bypassed for wiring to contactor ?
Rich G on Jan 16, 2018
BEST ANSWER: The pump speed is controlled by the toggle switch on the pump itself or may be connected a two speed time clock.
I have model 340039 now and needs replacing but is discontinued. Does this model 340043 fit the footprint of my model? Would I be able to drop it in and attach to existing lines?
Suzanne M on Aug 14, 2021
will this need an addtional switch at the timer box or is this drop in relacement for a pentair single speed pump number30039 with 2' lines does this qualify for edision rebate as well at low speed what is flow vs high speed gph?
A shopper on Feb 20, 2020
We have a SandPRO sand system, 3/4 hp--we need to replace the motor (pump) and would like something a little more powerfull, will this work and fit on our current system or do we need the entire system?

It’s lower profile than older units so it fits easier and I can’t wait till winter to use the slow speed to save money. It’s vary quiet so I would recommend this unit.

I am very pleased with this pump. Versatile and well worth a little extra money.
I am very happy with the Pentair SuperFlo 1.5 hp. There was a little difficulty attaching the two speed switch due to limited wiring space but the technician worked that out. The SuperFlo fit perfectly in the space of the old 1.0 Pentair pump. On low speed it is virtually silent. On high speed the pump really moves the water. I believe this pump will be perfect for the extra power required for adding a small solar panel system for winter use. I believe the electric savings and versatility of two speeds is perfect. Thànks for this option Pentair. Perfect.
