Can anybody tell me what my GPM is for my equipment?

Hey All,

Pump is a PE71-II-V (1.5HP SPL) 3450 RPM, I believe this http://www.speck-pumps.com/other/htm...ducts/E71.html is the pump, if you click the link on the right for "performance data" you can see the curves.

Filter is a Clear Water "High Rate Sand Filter" by Waterway. 22" round. MAX GPM is listed as 55, MAX Working Pressure is 35 PSI.

Clean filter pressure is about 10-12PSI, 1.5" flexy hose throughout. The few posts I found online says the Total Head in Feet for those specs should be around 45, and that lines up at 55 GPM. But those charts are based off of 3500 RPM, I doubt 50 RPM more makes a huge difference in GPM.

The reason I ask is I was thinking about picking up a "Slime Bag" to collect some algae that's on the bottom of my pool. I vacuumed a lot of it out to waste this weekend, but had to stop every 10 minutes to put water in the pool which took an hour or more to replenish. So I would like to try the 18"x30" X-tra Polishing Pool Vacuum Bag shown here http://www.cleanerpools.net/slimebag.php , and the specs show the max GPM it can handle is 60 GPM so I want to be sure it will "work" for me.

Looks like I will probably be fine but wanted to double check before spending over 50 bucks on this and finding out it wont work.

Thanks!

Without a suction measurement, it would be hard to say what the exact flow rate would be. I assume that you have a valve on the return line? Adjust the valve until you see about 20 PSI filter pressure and you can be assured that the flow rate is below 60 GPM.

I dont have any valves installed, though I have 2 waiting to be installed so maybe Ill do that first and adjust as recommended.

I ordered the Slime Bag regardless. I really need to get this crap outta my pool.

Please let us know how well it works -- good, bad, or indifferent! Please!

(And pictures would be wonderful!)

Slime Bag and new 30' vacuum hose has been delivered. Hope to test them out this weekend.

PoolDoc, ill try and snap some before/after pictures.

You can either post the pictures by way of Photobucket, Picasa, Flicker, etc. or email them to poolforum@gmail.com and reference the URL of this thread.
