I just bought a variable speed motor from you guys and I'm installing it on a Dura Glas pump. It's a 1.65 v-green, variable from 600 to 3450 rpm. What impeller should I be using?
Reply
Would recommend using impeller part # C105-137 PEB.

What is the flange size for the 4 mounting bolts center to center for the bolts?
Reply
Hello Ed - All 48Y and 56Y square flange inground pump motors have the same bolt pattern. The distance center to center on the bolt holes is 5".

Can this motor be installed on a 2 HP Pentair Whisperflo pump?
Reply
Yes, it can be used on a 2HP Whisperflo but you would have to change the pump impeller. The 2HP impeller is too heavy for the ECM16SQU. The impeller that you would need is Pentair part number 073128 (5074-27B).

I would like to install this motor on my square flange Pentair 3/4 HP pump. From what I can see, it will fit and I have the right impeller. Is this correct? Along with the shaft seal, is there anything else I should look at or change while I am in there?
Reply
Hello Rod - The ECM16SQU will work with your pump and impeller. Besides the shaft seal, we would recommend replacing the diffuser o-ring and housing gasket.

1. Shut off power to the pump at the breaker to prevent shock.
2. Remove the electrical whip from the rear of the motor.
3. Remove the clamp assembly bolts holding the seal plate to the pump housing. Remove the assembly and place on something that you can work on. (Bench or Something)
4. Remove the diffuser.
5. Using an Allen wrench to hold the rear of the motor shaft and prevent motor shaft rotation.
6. With Motor locked, rotate the impeller to remove it.
7 Remove the pump seal plate with Large Socket
8 Remove the mechanical pump seal from the seal plate and impeller.
9. Using the Go-Kit i bought from the site, replace the mechanical pump seal.
10 Then i took the new motor and attached the seal plate with the original bolts.
11. Using the same Allen wrench as before, lock the motor so you can attach the impeller. Make sure the Impeller is sized for the new motor. If its the same HP then the impeller from the original pump will work, otherwise use this site to help you get the right size. I find that hand cranking as hard as i could works.
12 Take the new motor assembly to the pump area and attach back to the pump housing with the original bolts.
make sure the seal is seated correctly.
13. Wire up the motor with the electrical lines from the old motor.
14 Turn on the breaker for power
15 Turn on the pump to test for leaks and make sure that it works.

My original pump was still running but wanted a variable speed pump to be self sufficient and save money on my electric bill. I haven't had it long enough to see if my bill will go down but I really like the operation of the new pump. Alot quieter than my old pump. I kept my old pump in case of emergency. So far so good.

After contacting INYO Pools, I received some very helpful advice from Rich Nagle at
Inyo Pool Products. He did some research and determined that the ECM16SQU is compatible with my current pump. Thank you Rich for your hard work... The replacement of the old motor was straight forward. I followed the step-by-step instruction video on INYOPools.com. They were very clear and easy to use. The programming of the controller instruction video was also very thorough and straight forward. It took me about two hours.

This is probably not a common scenario, but I had a 270 motor and the bearings went out after the warranty expired. It was my fault anyway by not installing the seals properly. I wanted to replace it with the smaller motor, but I wanted to use the 270 user interface on the new motor. Vgreen support said it was not compatible because the wiring harness was different.
I looked at the specs and the only difference is that the 165 provides 12 volts to the interface and the 270 interface requires 10 volts.
I measured the current when the interface was connected to the old motor and it was 100 ma.
I inserted a 20 ohm 1/2 watt resistor between the RS plug and the wire connecting to the UI. The RS interface is the same in both cases except the voltage. The resistor dropped the voltage to 10 volts and the user interface works perfectly.

Needed to replace pump or motor. Knowing that the replacing the pump would take piping adjustments including replacing valves I decided to go with replacing the motor.
InyoPools was extremely helpful in assisting me via chat in finding a replacement motor that would fit my pump and be the right speed and power for my pool.
My current motor was a 1.5 HP with at 1.1 Service Factor, yielding a max 1.65 HP.
They helped me find the right replacement once I gave the specifics about my pump, an old American UltraFlo.
Rather then ordering a single speed pump at around $200+, I opted for the Variable Speed Motor at twice the price. From a cost perspective it was a wash since my energy supplier (PECO) in PA is offering a $200 rebate for replacing single speed motors with efficient variable speed ones. So I went with this one.
It is a great motor and itself was easy to install once I had all the parts I needed, i.e. Gasket Go Kit with motor seal and o-rings necessary.
In my specific case, I was not able to re-use the seal plate for the pump, as I was unable to remove it from the old motor, so I had to purchase a new seal plate. InyoPools helped me out with that product as well.
Motor is installed and working well.

I looked hard and long for a variable speed motor for my pool pump. I asked if this motor would fit on my pump. I was told yes. I was even given the right part number for the gasket kit needed to put the motor in. Got the pump motor in a couple of days. Took the old motor off. Read the instructions and had the pump motor on and running in a couple of hours. Programed the pump to what I needed it to run for. Started the pump up and it has run great since I put it on. Nice an quiet.

First of all I bought all the tools needed to the other side of the house which weren’t too many. I remembered watching the tutorial that was linked to me by the company and there was no issue whatsoever as I followed the instructions from memory. Even programming the variable speed was easy. It seems I was worried for nothing.

Decided to go with a variable speed motor to save energy cost. Replacing the motor and seals was a chore. The new motor must of been a little longer than the old one so the power wires were short. Had to buy new wire and replace it. Ran into a few unexpected problems along the way but got the job done.

Decided to do some plumbing alterations before installing pump. Discharge (outlet) of pump was a hard 90 over top of old motor (in line) and in the way. Turned pump new outlet 90 degrees from axis of motor allows easy access of control module on motor.
Took me a few moments to figure out which electrical wires on the breakers was red and black, both lines coming off breakers were same color. Line feeding breakers from house, one red and one black, indicated which breaker/line was which.
I choose to eliminate my mechanical timer between breaker and motor, since motor module has 24 hour timer. Curious what the pros do in this situation. Also installed new wire from breaker to motor, old single strand wire (27 years) was stiff/brittle. Used same gauge (rated 12 AWG) new multi-strand wire.
Bought new weather tight conduit/wire connector from local hardware store to connect conduit/wire to motor control module. Motor installation was relatively straight forward, both wiring and I mounted it on the old (27 years) Duraglass motor mount.
I bought a new pump seal with the motor. Seemed prudent if your investing in new motor and time to replace it, might as well install new pump seal. Motor running nicely.

Pros: Saves money, quiet at low speeds, inexpensive upgrade cost, fast return on investment, compatible with most pumps.
Cons: Loud at higher RPM's
I ordered this motor to replace a 1.65Hp AO Smith sq1102 motor that was costing $125/Month to run. I ordered it on Saturday and after stewing on for a day i contacted inyopools by email late Sunday and asked them if they could change my shipping to 3 day. Monday morning first thing i got a response, they changed the shipping to 3 day for me and didn't even charge me for it...Thanks! When the motor arrived Thursday I opened the simple packaging and found a solid feeling motor and a user manual. When i purchased this motor i received an email with a downloadable owners manual attached so I was able to get quite familiar with the controls by the time I received the motor. I had already rebuilt my pump (P4E6E Maxi Glas), and my motor last week, so being familier with everything it only took me about 25 minuets to replace the motor and wire it up. It was very easy to install if you have basic mechanical skills. The motor started right up and primed the pump in about 1 minuet. I would say it is a bit louder at high RPM's than my old motor , however I didn't buy it intending on running it at high rpm that much so that is okay for my situation. The controls are very basic and simple to use, for me at least. I think that anyone who reads the programming section of the very short manual will find it easy to set up the way you want. About the savings.... Based on my calculations using an amp probe and a voltage tester, my electric bill should go down from $125.00 a month to $26 a month. My old motor used 2,200 Watts of power, so 10 hours x 2,200 Watts is 22,000 Watt hours or 22KW. At .19 a KWh that is $4.18 a day or $125.40 a month. The new motor running at 3100 RPM's uses 1,000 watts, I will run it @ 3100 RPM's for 2 hours = 2,000 watts (2KW) Running at 1850 RPM the motor uses 210 watts, so if i run it for 10 hours that's 2,100 watts of power used. At 600 RPM's it only uses 33.33 watts so for another 10 hours that's only 333 watts of power. If you total all power used for 22 hours of operation that is only 4.433 KWh x .19 = .84 a day! That's $25.27 a month. Wow! Based on what I have read and some basic calculations I believe that I will be pumping the same quantity of water through my filter in a 24 hour period. With the above calculations the motor should pay for it's self in less than 6 months. If you have a pump that works and this motor fits it, don't hesitate to buy it.

(4 out of 5 stars) 5/5 for three years of operation.
Reviewed By: Inyo Customer ()
To start, when I first ordered this pump in January 2020, I should have come here to review it for 5/5 stars. It was night and day compared to the old sta-rite single-speed pump I had to replace, the cost savings were immediate and noticeable every month, and it ran so quietly and efficiently. It was amazing! But like another recent reviewer experienced, the last few months I've noticed significant corrosion around the motor body casing and seals in what is a generally dry install location. I am wondering if it is because it is pumping a saltwater pool or is reacting to the pool chemicals internally, or as an inexperienced new pool owner I didn't do enough of the right maintenance to keep it in better shape. It started making an awful sound a few days ago and unfortunately I can't take it apart to investigate because the nut holding the fan is rusted, the screws holding the rear cover stripped off, and I'm left trying to decide if I should replace it with another (it's a great price compared to the other variable speed motors on the market! And I know it will work great to start!) or if I should consider another option... it'd be easier to decide if it was still <$500!! To conclude, this has been a great pump. I do not understand the root cause of my particular failure but what I suspect is I could have done more maintenance and inspections over the course of the season to prevent the corrosion from going so far. Probably common knowledge for those who have been doing this longer, but something to keep in mind when making your purchase.

I'm not sure how to rate this due to the corrosion of the motor housing, leading to motor failure. This motor was bought and installed a little less than the three years ago and it has seized. All my pool equipment is kept under a roof covering but does get wet when I'm cleaning the slab that it sits on. For a product that is designed to be outside, it's incredibly disappointing to have to replace it, and at today's price, $218.00 more than originally. It worked great while it lasted! My original single speed Pentair lasted 14 years and was still running when I replaced it!

(5 out of 5 stars) Fantastic Upgrade for 1HP single speed pump.
Reviewed By: Inyo Customer ()
Motor works great! I upgraded from a 1 HP motor and this is a nice uptick i power. Love the power level/timer function so you arent running the pump all day at 100%. Noticed a nice drop in the my electric bill since the old pump was running 24/7 on full tilt. NOTE: Make sure that you upgrade the Impeller for the best results. Replace the shaft seal while you are doing this since you will be in there anyway.

(5 out of 5 stars) Great product, easy install.
Reviewed By: Inyo Customer ()
Amazing. This was my first pool equipment "upgrade" ever. I followed InyoPools video and this thing popped in with no trouble. I had to do a slight piping reroute as the control module on top of the new V-Green motor was a lot taller than my old, single-speed motor. Took maybe 15 minutes, so no big deal, but you may want to plan for that, if your plumbing runs close to the top of the old motor. I noticed an immediate drop in electric usage. Great product, I think the payback period will be measured in months, not years.
