The Power Defender VS 1.4HP uses a Nidec variable speed motor, which allows programming flexibility and open communication with a variety of external system controls.
I have a Pentair WhisperFlo WF-24 1hp pump. Would this be a direct drop in replacement? Do I have to change any plumbing?
Hi David, When using the supplied Whisperflo Base which is included with this pump then yes it will be a direct drop-in replacement.
What pumps do you recommend as a replacement to a 1.5 single speed Stayrite pump? Its housing has a pin hole leak. It is a 1.5 HP single speed motor/110 volts /1.5” pipe. Kidney shaped pool with a small 3 jet spa in one end. 2 skimmers – 1 in the pool & 1 in the spa w/ a cartridge filter underneath (suction side.) A Hayward pool cleaner runs from the pool suction side skimmer. 3 manual suction and return valves control water to/from the pump. Est 12 to 20,000 gallons of pool water.
Hi John, Thanks for your photos those are helpful! Based on what you have explained I would suggest this 1.4 HP Variable Speed Pump. This is one of only a few variable speed pumps that can be wired 115V. The plumbing ports on this pump are not in the exact same location as your current pump so you will have a little re-plumbing. Also the ports on this pump are 2" so you will use a 1.5" x 2" bushing to go from 1.5" plumbing up to the 2" ports. You will save a ton of money on your operational costs by going to variable speed.
I have a SP2605X7 super pump 3/4hp (w/ dead motor) in 20k gallon pool with Hayward S244T filter. I'm trying to decide between motor replacement and complete pump replacement with a variable speed pump (perhaps PD-140?) to save energy.
14 PSI on filter during normal ops. I also have booster pump for polaris vacuum. Not sure of my TDH but my pump is about at water height, 1.5" pvc plumbing. See attached image for pool image showing pump location, skimmer/outlet locations, and plumbing. Thanks!
Hi Michael, I would lean towards a Variable Speed Motor replacement for a few reasons. First I will layout the items you would need for a motor replacement... You will need this 1.65 HP Century Variable Speed Replacement Motor this Hayward Super Pump Seal Kit and this Hayward Super Pump 1.5 HP Impeller The reason I would suggest this route is that I like the 1.65 HP Century Motor a little better than the 1.4 HP US Motor on this pump. You will have no re-plumbing if you just replace your motor. You will have the ability to ramp your HP up a little higher (1.65 vs. 1.4) if needed and the cost is less.
Now that you have suggested a round flange motor, I’m all confused. The dead motor seems to be square flange (see attached picture). Can you help me decipher my pump model (model numbers wore off) and motor replacement needs? Attached are pictures of my pump and dead motor. Thanks! One more factor to consider is that I'm pretty sure I'm on a 115 V wiring setup.
Hi Michael, The Super Pump is a tricky one as it looks like it is a square flange motor but it is actually a round flange motor. There is a motor mounting plate on the motor which is removed and once removed it reveals the round flange motor. You can see this better by looking at this Hayward Super Pump Parts Diagram take a look at key #14 (motor mounting plate) which is removed from key #22 (the motor). See my last reply in regards to 115V and 230V.
Thanks for the prompt response. One other factor to consider: I am currently wired for 115 volts (at least i think I am). Will this Century replacement motor work for a 115V circuit, or will it require 230V line to be run?
I am converting to a salt water pool. Is this pump compatible and does salt water void the warrenty?
This pump is saltwater compatible and salt applications do not void the warranty.
My pool is only 10,000 gallons. Is this pump going to be overpowering? The current pump is 3/4 horse single speed but I want a variable so I can run it longer. The filter is a Hayward Pro Series High Rate Sand Filter. Specs are 20 GPM/Ft sq. filtration rate and 62GPM design filtration and backwash rate.
Hi Richard, This pump would not be overkill, most of the time you will be running it at pretty low speed that is where the energy savings comes from. However, you will have the ability to really ramp up the HP for things like vacuuming or if you ever get into demanding water conditions like an algae bloom and need to increase your filtration.
I have the Hayward aqua logic automation system the board is rev s / rev2.85 . Can I hook this pump up to my system? And if so how do I wire it, my Northstar has 4 wire hook up and the vsp has 3 wire.
Yes you can hook this up to your Hayward Aqua Logic however all of the programmings will be done on the controller on the pump controller. So the AquaLogic would power the pump on and off and then what you have programmed on the pump controller would take over from a programming standpoint.
Do you guys sell extended warranties? If I install it myself does that do anything to the 2 year warranty?
Hi, Anthony. We do not offer any extended warranties. If the pump is self installed, you're still eligible for the full manufacturer warranty.
I have a 1.5 hp Hayward northstar, will this pump be a good replacement for my original?
Hi Anthony, Yes this 1.4 HP Variable Speed would be a great replacement for your 1.5 HP Northstar. You will save a ton your operational costs by going to a variable speed.
I currently have a 1.5 hp Hayward pump with 1.5" ports. Can I up grade to a pump with 2" ports with causing an issue with the rest of the plumbing.
Hi, Robert. Yes, you can install a pump with 2" ports without causing an issue.

After carefully researching VS pumps I decided on the Waterway PD140. The utility company provided a $350 rebate, the warranty is 2 years even with a DIY install, and it’s made in the USA!
The pump showed up in a very solid box with tons of formed foam. Adapters were provided for my 1 1/2“ pipes and the variable height for the base were very helpful for the install.
Wiring was easy considering my previous pump was 220 just like the new pump is pre wired. Make sure you have a 1/2” seal tite connector - the pump does not come with one.
The pivot attachments on the pump are great and make plumbing it easy with the flexibility.
The new pump is quiet, powerful and doing a great job on our 28,000 gallon pool and spa. Our old pump was a 1 hp and our system ran at 20 psi - same as the new pump in 3450 rpm....
The only improvement that I would like to see would be an easy on - off override to continually run for heating or opening.
This is a great pump and I highly recommend it!

Installed new unions that. were sent to me replacing the defective ones. Defective ones couldn't be installed in the pump. So it was just installing the new ones that were sent and connecting the hose from the pool and the hose to the filter.
(5 out of 5 stars) Inyo Recommendation and worth it

This replaced and old single speed pump. It has 3 speeds plus it self primes for 3 minutes with unbelievable amounts of suction. My pool was cleaned up in 24 hours.Set up is easy. Would purchase again. It was a Inyo recommendation and a good one at that. Good value compared to others that do the same.
(5 out of 5 stars) Excellent VS pump value

What a good pump value. It is the perfect VS pump for old pools like mine with only one suction line and all 1.5in plumbing. My old pump was a 1hp PacFab HydroPump with an open face impeller so this pump is a great upgrade in water moving capability and efficiency. I love having the capability of kicking this pump up to full speed for backwashing. It backwashes much more effectively than my old pump. I have an MX-8 suction cleaner and my old pump could not move enough water to make it run well. The PD-140 at only 2500 RPM provides enough suction to let the MX-8 climb the pool walls. I run it at this speed for 4 hours and then kick it down to 1500 RPM where it will still move the MX-8 around the pool floor. This pump is very quiet too compared to my past pumps. This pump also has a built-in freeze guard. In N Texas this is a very welcome feature not often found in lower power VS pumps. This pump also comes with swivel unions, which eased my installation. With regular unions I would have had to remove my old plumbing and start over. At this price point the PD-140 is a great value and I am happy with my purchase.
