OK guys, I have a chance to buy for $200 this motor (not sure of pump):

MotorSpecs.png


And this filter: S244T

I presently have this motor:

this filter:


FT2 M2 GPM LPM PSI BAR LBS
S190TSCP 1.8 0.17 45 170 50 3.45 175

and this filter: S210T



FT2 M2 PSI BAR INCH LBS
S210T 2.2 .20 50 3.45 18 200


So what would you guys do? I am more confused then when I started.
 
That S244t is about 350 new and although it is still a bit small for your pool, it can probably do the job with longer run times. It is a better choice than either of you other filters, though you could start with the S210T and just expect to have long run times and see how it goes.

I can't read the motor/pump labels. Could you make them larger/higher res?
 
I can give you the rundown on the specs, one is:

Century Pool/Jetted Tub Motor 1081/1795 Pump Duty
volts:115 amps:12.0 hp:1.0 hz:60 sf:1.00 type: SP serial:BU3-02 part 7-186884-20 AMB: 40

The other is:
Century Centurion Pool and Spa Duty
volts:230/115 amps:6.0/12.0 hp:1.0 hz:60 sf:1.00 type: CX serial:BU1-12 part 10-184981-22 AMB: 50
 
It seems, and I can be way off here, but the pump I have a chance to buy runs a 6.0 amps at 115v, whereas the one I already have runs at 12 amps at 115volts. So the one I have a chance to buy would be the more efficient and therefore cost less to operate.

And that dreamline filter has a 45GPM flow rate. That would equal 2700 Gallons per hour X 12 hours = 32400 gallon per 12 hours filtration rate, which would give the pool 1 full turnover in a 12 hour period. If that is correct, why would I have to run it for more than 12 hours in a day? I have read so much now I have confused myself.

I plan on running the pump on a timer at 12 hours at a time.

The new motor is dual voltage so it uses 6 amps at 230 v OR 12 amps at 115v. Same as the old motor. The energy use will be about the same.

Thanks Mas. I guess I will buy the new set up, hope the pump works good (I will test it first), and use that and sell the others. I think the pump I am buying is 1 HP uprated. Sorry for asking to be spoon fed, but I thought I had all this worked out and we are installing this weekend and I still have a bunch of questions and am running out of time. I have a bunch of people coming over on Saturday and need to have all my ducks in a row.
 
Another question : ) Would it be more logical for me to run that 175 lb filter and spend the $200 I was going to spend on the bigger filter and pump and buy the 2 speed pump? Then the electricity usage running it at 12 hours on low for a full turnover on the smaller filter would be more efficient than running the 1 HP at 8 hours for the bigger filter? The pump would run longer, the turnover rate and filtration would be the same, but the energy usage would be less. I would just have to back wash more ofter because the filter is smaller. Does that sound like a better scenario? I am looking to keep my energy usage down if possible, if you cant tell.
 
The energy use on high vs low is about 4:1 and the flow rate is 2:1 so overall, you will save about 50% in energy costs.

I think you have pretty much got it. 12 hours is pretty long to turn a poolover. ANSI/NSF 50 guidelines for "public pools" is a turnover in 6 hours. The issues might be how long it takes to clear a pool with algea and more frequent backwashing needed. Neither of those is a show stopper, but you did ask "if it was your pool." :)

A little more detail on flowrates: although 45gpm is the "max" flowrate that hayward specs for that filter, they are assuming a flow rate of 20 gpm/sq.ft. which is actually not ideal...15 gpm/sq. ft. is considered better (ANSI NSF 50). So that filter is 2.3 sq.ft.X15 gpm/sq.ft.= 35 gpm. If your pump can deliver that low of a flowrate (determined by your pump and the rest of your plumbing head loss), your turnover would be about 12 hours. Good news is, if you decide to do the 2 speed pump, your pool would turnover in a little less than 24 hours, so it would be practical to run it 24/7 on low and still get proper filtering for a clear/clean pool.

Where can I find the flow rate on those two pumps? I have been using
The gpm flow rates on the filter. I haven't seen the flow rates on the pump

The information you gave us is on the motor (century), but I don't think it tells us anything about the pump. Is there any other label on them that has another manufacturer listed?

The black pump is a Superpump.

Is the Dynamo a different pump?

Your signature says you have a Powerflo.

A little confusing to say the least so why don't start over and explain exactly what you are trying to do and please do not leave out any details.

If you do have a 1 HP Dynamo, then the flow rate will probably be around 50 GPM but it depends on the plumbing configuration.
 
Sorry mas. I know you are trying to help me out and I appreciate it. So here goes. I want to keep my electric bill down of course, but I have to make a choice and want to try to keep from buying a whole new set up. I have a 33' round pool. I have the opportunity to buy a 300 lb sand filter listed above for $200 that comes with that pump that is attached. Not the gold one, the black one. It is a 1 HP, but I have not layed my eyes on it and the guy doesn't know what kind of pump it is. It came off an inground pool. I also have a Hayward s210t filter that I don't have to buy or a dreamline s190tscp that I can use. I am going to have 2 returns and the pump is going to be at ground level while the pool will be buried 1 foot. I plan on running 2" hard pipe unless you guys tell me it would be better for me to run 1 1/2. One of my questions was should I just spend the $200 I was going to spend on the larger filter and get a 2 speed pump and use one of my existing filters or should I buy the larger filter and use the 1 HP pumps I have? Energy efficiency wise and to keep the pool sparkling. The equipment will be located directly beside the pool. I don't have any information on the pumps, just the motors. I know that is a key piece of missing information. I wish I could find out, but the stickers are gone off both of them. One I know is a dynamo, but that is all I know. I think I covered everything.
 
So I can tell you for sure the pump in the picture above is a Superpump and if you are sure it is a 1 HP then it is the SP2607X10. One think to keep in mind is that an IG pump is larger than an AG pump with the same nameplate HP. So I would not recommend using an IG pump on a AG pool especially if you are using a small filter. There really isn't much difference between a 300 lbs filter and a 200 lbs filter so I would stick with what you have a get and two speed pump. Another option is to just replace the motor in your current pump (1 HP Dynamo?) with a two speed motor. This would be a little cheaper than replacing the entire pump but you can do that as well.
