My ten year old pump is giving up the ghost so time to upgrade. Tried a few things to get keep it going, here is the thread: filter-pump-electric-motor-problems-t42330.html
So my filter pump is still limping along, but looking to upgrade. I am thinking two speed for sure, maybe a new electric motor, maybe entirely new pump. And I think my existing pump/motor is bigger than I need.
Existing specs on my setup:
10 year old pool and equipment
17,000 gallons in ground plaster pool with in ground spa
Sta-rite filter pump Max-E-Glas-ll pump, high head, http://www.poolplaza.com/C-Sta-Rite-Pumps.html upper left pump, no longer manufactured
filter pump motor, 240v-A. O. Smith 1.0 HP sf-1.65 square flange replacement pump: http://www.poolsupplyworld.com/pool...smith/century/squareflange/products/B2848.htm
Booster pump for polaris 280 cleaner
separate jet pump for spa
separate water fall pump
Big Sta Rite Cartridge filter-model s8m150-max pressure 50psi, max flow rate 125 gpm
2 inch PVC suction and discharge both, pump is maybe 30 feet from pool, same elevation
Jandy 1400 SWG
Electricity rate: 14 cents/kwh average
Jandy Aqualink RS6 controller in the house, Jandy switch/relay cabinet next to pumps.
Thinking of adding solar to the roof (1 story house) this or next summer
With the big high flow rate (I think) system and all my auxiliary pumps, I only run the filter pump 4-5 hours a day. This is mainly to so the SWG keeps the chlorine level up. Pool sparkles at a 4-5 hour run time (using BBB method) in the summer. So I figure the I am getting plenty of turn over in 5 hours. But I think the 10 year old 1.65 THP pump motor is sucking a lot of electricity (and is dying) so I am looking to upgrade.
Option 1: Just replace the pump motor in kind: http://www.poolsupplyworld.com/pool...smith/century/squareflange/products/B2848.htm
Pros: Cheap fix ($225) and I know it works, plenty of power for solar on the roof.
Cons: Sucks electricity but should be better than my 10 year old electric motor.
Option 2: Get a 2 speed motor and keep the old pump: http://www.poolsupplyworld.com/poolsupplies/poolmotors/products/EB982.htm
Pros: Still cheap ($300), 2 speed, more efficient, saves on electricity.
Cons: Still using 10 year old pump, may need to install switch, not sure how to wire to existing Jandy RS6, might not work with solar on slow speed.
Option 3: Get a new pump and motor, say a superflo : http://www.poolsupplyworld.com/poolsupplies/poolpumps/manufacturer/Pentair/products/340042.htm
Pros: ($475) not to expensive, new efficient pump, probably work with solar, start on high, the switch to low speed, energy efficient
Cons: Not as big as my existing pump (but I think existing is over sized), Need to re-plumb PVC (not that hard), Need timer or way to interface with Jandy RS6
Option 4: Just get the near Cadillac model : http://www.poolsupplyworld.com/poolsupplies/poolpumps/manufacturer/Pentair/products/011018.htm
Pros: very efficient variable speed, should work fine with solar, has built in timer
Cons: getting pricey ($900), probably will not interface with Jandy Rs6,
So at this point I am leaning towards option 3, assuming it is big enough to do what I want. A 3/4 HP fully rated pump may do what I need to. I do what some safety factor for the solar panels in the future. And the whole interfacing with my Jandy Aqualink RS6 has me worried to.
Opinions welcome.
