I've 22.5k gallon in-ground and my 18-yr old Hayward SuperPump motor/pump is leaking.
I'm replacing motor and pump housing and I guess with a variable speed setup.
I've no exotic water features; just a skimmer, floor drain, and two outlets. Piping seems to be all 1.5" pvc.
Suggestions on brand, THP, and model if you've a favorite(s) would be greatly appreciated.
I only have a Leslies' to shop at and I'm not too impressed with the information I've gotten from them in past on things.
I don't have a salt system nor heater and due to up-front costs, will likely not get either in my future.
TIA!
 
Calimar VS. Best to get the full 3 hp version.
Assume you have 220V at the equipment pad.

Thanks MKnauss.
My desired flow is 35 gpm and 32 Total Dynamic Head.
I'm likely not grasping the Performance Curve right for the CMARvsp3.0 and my situation but it seems only at the 2500 RPM does it achieve those numbers. At 1500r/min, it is below the 35/32.

Is this desired?
At higher speeds, it would appear to deliver too much. Wouldn't I need a lower powered unit?

PS. I've never heard of CaliMar.
Are they comparable to the Hayward, Pentair, or Jacuzzi brands?

They are inexpensive Chinese-made pumps that are about 1/3 - 1/2 the cost of the big names. Many on this blog use and and enjoy them.
Are they comparable to the others? No/Yes. They move water. You can get repair parts for them, but may not be able to get a repair person to work on one as they are not as common as the big names, but at the cost it could just be replaced and still be money ahead.

Not sure why you are worried about water-flow rate and understand that the head changes with the speed of a VSP. If you need 32 GPM, the Calimar will deliver it at 1500 rpm, and the total head on your system at that flow could be as little as 10 which means the pump would be capable of about 40 gpm. You can try to calculate the actual head on your system, but unless you know all the plumbing underground, it is a "best guess."

Still not grasping the value of these curves vs how to set up the variable speed and for how long on each speed.
I'm still unsure; am I better getting a higher THP motor than lower in general?

The largest in THP will move more water for a given RPM and save the most in energy (money) for the amount of water moved than a smaller THP and the difference in cost can usually be recovered in less than a year. Everything that you ever learned about how to filter a pool (basically a turnover rate) has gone out the window.

We run the pump at a speed that allows for the pool to skim (at least for a while), mix the chemicals (which tend to migrate to the top of the pool when it is not being circulated), then drop in RPM to satisfy the needs of any piece of equipment (SWG?) or water feature. Many, with a VSP, just run their system 24/7 at a speed that runs the SWG and keeps the water healthy. Since all pools are different, you just "play with it" until you find what works for your application.

Mine runs 2 hr. at "skimming" speed, I have a very dirty yard for pool purposes you may need less, then 13 at low speed, enough to get the SWG to work, then stops just before my utilities "peak" hours where electricity costs more. I believe, though I haven't checked in a while, it costs me about $20.00/month to do it that way. Water sparkles and there is enough chlorine to do the job. If it costs a bit more now, I still need to filter the pool regardless, and I know it is costing less than my old single-speed pump that ran 6 hr./day. If I need to kick the speed up a bit when the pool is in use, I can. Then it just automatically reverts back when done.

In my opinion, the main reason to use a larger variable speed pump is to make it quieter.

If you don't care about the noise, the smaller pump should be sufficient.

If the sound matters to you at all, get the larger pump because the difference can be significant if you would need to run the smaller pump over 1,725 rpm.

The overall power use difference is not as much as you might expect.

A 1.5 hp variable speed pump will use about the same amount of power as a 3 hp variable speed pump when moving the same flow through the same system.

The only benefit to going to a larger pump is to be quieter.

The efficiency difference is negligible.

A 1 hp, 2 hp or 3 hp pump will use about the same amount of power at the same flow rate below 100 GPM.

If you want to know for sure, you can check the efficiency at different flow rates for different pumps.

hp............Flow.........Efficiency.

1.5..........30....................35
3.0..........30....................34

1.5..........75....................53
3.0..........75....................55

+1 for Calimar 3HP VSP. I'm using it on my 25k gallon IG pool. The Calimar replaced a Hayward 1.5HP single speed super pump. I installed the pump and a Blue-White flow meter from Amazon. As an engineer (grin!) I wanted to know if I was over-driving my filter, pipes, etc. At 2700 RPM's and my config (very low head), I'm getting about 55gpm flow rate thru the 1 1/2" pipes and filter, which is the perfect flow rate for my filter. Flow rates are higher if I put the filter in bypass mode.

The pump was inexpensive enough that it was a no-brainer to get the 3HP AND the extended warranty. I run 2 two-hour periods of 2700 RPM, and 2 nine-hour periods of 700 RPM, and a 2 hour rest period. I'm saving about $50/month on my electric bill as well.

IMHO, the manual doesn't completely describe how to use the control panel, so it took a little trial and error to get to where I understood it, but I'm golden now and very happy with my purchase.

Hope this helps...
 
If the pump wet end is in good shape You can just change the motor end to a vsp which then eliminates the hassle of fitting another pump which doesn't match up to the old plumbing. Neptune has a good vsp 2.7 hp which is an easy upgrade.
 
I have 2 varients of the chinese vsrs including 2 calimars. one a dohenys branded harris is going on 3 years. i seriously doubt they're really 3hp but they work.

i hate vsrs though ,...i just want to slam an single speed pump in and a program one mechanical last forever timer without jumping in hoops and have plenty of juice
to run water features without over engineering timing of that and swg and cleaning or spending thousands on overpriced crappy pool automation digital displays or needing another hobby....but like everything else today here we are....so keep that in mind.

i have 2 pools in 2 locations, one smaller probably i dunno 14-15k maybe, built in 2000's 2" plumbing with water features (spa, spa fountain and some wall fountains). Lot of vegetation from florida storms there (requires more manual overrides for pressure side cleaner).

one old big 8 foot deep diving board era kidney shaped 70's pool no water features 1 1/2 plumbing..screened.... the calimar 3hps do fine at both but best at the old school pool. I really have no idea what the gallons is of the kidney pool but i figure the deep end puts it up there to close to 18k or more maybe , i did an area calc but forgot it.

Where i notice vsr falls down is the pressure side cleaner and it's being uncovered..lots of manually balancing there, or you either gotta automate valves or get a robot,etc but then you really want a cleaner in 24x7 anyways there. The small one has spa features wall features and it struggles the most to power the pressure side cleaner , so much so i have a robot cleaner i've never unboxed (and probably never will as the pressure side is 24x7 and last ages). But for sure in both locations with some tuning of features,etc they get the job done.

However it does great at the big ol school pool with no water features and running the pressure side cleaner there and like others say it's pretty quiet most of the time.

didn't do calcs just ordered the 3 speed hooked it up let them run default schedules and if i noticed anything weird i figured i'd look into it.

Check your power company for rebates...these cost me a few hundred bucks only after upgrading but i get a healthy energy star rebate...so payback is literally like 12 months for me in florida. I'll probably flip the small pool
back though to single or 2 speed after it's vsr dies i just don't like it at that pool and don't want to load up on a bunch of tech to manage.

edit: and don't forget if you go vsr and have swg you gotta then balance the timing of those since now your timer is at the pump and preferably not rely on the flow switch of the swg.
 
If it's just a seal leaking and the motor is still working. A seal kit is only $20 or so and takes a half hour or so to install (once the pump is accessible).

If you are content with the way you set up is working and the electric usage is okay, it's hard to beat 18 year of service.

A VSP will cost less to run, and will likely be cheaper in the long run than single speed. If you ever plan to go salt, a VSP makes even more sense. The Calimar VSP are the same or less expensive than name brand single speed pump. A name brand VSP is $1000 to $3000 range. Also from the feedback seen on this board all mfg seem to have issues from time to time. The feedback on the Calimar pumps and its retailers is that if there is an issue they are very responsive to address them and resolve the issues.
