Submersible water pump question
Posted by FJ and G on Wednesday, January 21, 2004 2:30 PM
Can anyone recommend one for an indoor layout. The water would need to be pumped about 6 to 8 feet high and the length of the layout stream will be approx. 35 to 40 feet. Also, I want the pump to be fairly quiet.

Thanks.

Hi there,
Aquarium pumps are generally submersible. Check with an Aquarium shop to see if they can recommend a pump for you. Most pumps are quite quiet also. I am building a pond myself on my indoor layout. Only a small stream though. Later eh...Brian.

Thanks,

Didn't know the pumps were that powerful to lift the water than far and high. Will check, though.

Hi again,
My Brother-In-Law is an avid fi***ype of guy. When we first met he had a set-up in his apartment with around 30 tanks. The pump he had was huge. You could also look into a pond pump. They sell them at Wal-Mart and come fairly large also. Hope you find what you need. Later eh...Brian.

Most regular submersible garden pumps should have the "oomph" to push water up eight feet. If you have a 'mini' submersible you might have a slower and possibly inadequate flow. The physics of the situation are simple. Water weighs about 8.7 lbs per gallon. Most of the submersibles that I've seen have at least a 20' lift or about 170 lbs. of lift. If your run of 30 to 35 ft is all uphill plus a final push going straight up, of say another 5 ft, may pu***he limits of your pump. It may work in the beginning, but as time goes on, wear and tear may take its' toll. Most garden centers that handle equipment for water features should have a chart that can help you figure your needs rather than having to do the math by hand.

You want to use a "Mag Drive Pump" used for ponds. They start at around 35 GPH (gallons per hour), and go up. They usually are rated at a 2foot lift. You can use a larger pump and put a valve in the outlet to control the amount of water flow you want. Mag drives are quiet and cheap to operate. I use 4 in my ponds for several years now wiyh no problems, The best prices i have found are from DRs Foster & Smith, formerly pet warehouse. John

I have been using a submersable sump pump for about five years now with no problems so far. Sump pumps push a lot of water so my 40 foot "river" runs deep and wide with a lift of about 5' or so. You can find these at Home Depot etc. etc.

thx for your replies:

Old Dad,

Is the sump pump from Home Depot as quiet as the Mag Drive Pump that John suggests?

John,

Why do you use 4 pumps? Also 2 ft lift is too low but you seem to indicate that mag drive pumps come in much larger sizes

FJ andG, I use pumps for differnet things, one is for top to bottom circulation in a pond bulit above ground, but still is connected with the other 3. one I use in my Bio-Filter tank to add aeration for better water quality, and one for other water features not run off my 2400 GPH main pump. If you find the web site I mentioned, www.petwarehouse.com You will find rhe whole range of pumps. one will work for you. By the way Mag drive pumps do not have water seals to keep water from getting into the motor aera, so they last a long time. The motor windings are sealed in epoxy, thats why I use them. Most all pumps are rated at 2 foot lift, just increase by 1 or 2 sizes for your extra lift, John
