Just for the purpose of circulating the water in a pond. Can this pump work by using a 500gal/h pump or lower to start the pumping?

This ejector pump only works while water pressure is applied to the inlet (black) connector. 8.33 gal/min will make it work and produce a higher flow at the outlet wile the jet part is submerged. More pressure produces more flow and higher lift. Hope this helps.

If I understand your question, I think it would work. Water goes into the pump through a garden hose, water gets sucked into the stream via the built in Venturi tube, and the combined water leaves the pump through an attached hose. When draining a hot tub, I noticed the pump sucks more water per minute when the pump is deepest in the water (more water pressure acting on the Venturi tube).

I hope I understand your question correctly. At 5 feet above the water surface, these pumps experience a reduction in flow of about 50%. Example a pump rated at 700gph actually has a flow of 400gph at 5 feet above waterline. To visualize the flow, imagine your garden hose pointed upward with the valve about 1/3 open... at 400gph the stream of water would rise about 6 inches before topping out. If that is enough water then a 700gph pump is enough. If you buy a 950gph or 1200gph you can restrict the outflow with a plastic valve from your hardware store if it is too much. If you already have the fountain, try connecting your garden hose and adjust the tap to the ideal flow rate. Then disconnect the hose while leaving the water running and then let the water run into a pail for 1 minute. Then measure the water that has ran into the pail and multiply by 60 to get gph. Then take that total and multiply by 1.75 and also by 2. The two calculated numbers will give you an idea of the minimum sized pump and the maximum sized pump you will need.

I'm not sure I understand what you are trying to do. This float switch is designed to start the pump when water level gets too high and shuts off the pump when the level gets below the bottom float when installed in the upright position. I don't know the size or location of your pond but if outside and wind is a factor, you may have to install the float switch in a stilling well.

It did not work for my in ground. It would not prime when above the water level. If your pump sits below water level it may work for you.

This pump is meant to draw water from a source (ie pond, containment etc)....I would look at purchasing a sprinkler boooster pump for your purpose.

I have a 380 gal pond and use the 1000 fishmates filter and a 1000 gph pump. The pump is a bit overkill but the filter is fine. You should have no problem with the combo you are asking about. I would not go bigger than the 800gph pump though.

It should but I would find out the starting surge wattage of your pump first. I know a 1.5HP starting needs about 6000+ starting wattage which is too much for this as it's only a 4400 starting and 3400 running. However, if yours is only a 1/2HP, you might be okay. Check it out first.

Your float turns a switch on and off on or near the motor. If you can lock the switch in the on position (many options), and your pump runs full time, you can use this switch by plugging it into the outlet first and then plugging the sump line into the control. Directions aren't the best but mine still works. Good for up to 14 amps. I'm always cautious with low stock items. They could be returns but Amazon backs up their products.

You will need a pump, I am running two 330gph pond pumps, I have them both submerged in the last compartment of the sump. I am running a corallife 65g skimmer in the center compartment.

This is probably not the best choice. For each 33' of head (vertical lift of water plus restrictions in discharge line) the pump will have to overcome ~15PSI (14.7). The pump has ~ 55 PSI. Additionally these diaphragm pumps don't like any trash that may be sucked up from the lake water. Even if you put a filter, the restriction on the suction side may be too much to overcome. Technically speaking the pump should do it, but it is probably not the best choice. Additionally the pump is for intermittent use, so if you plan on pumping for a while the pump will overheat and shut off. - Good Luck

I believe so. I am going to get another for my pond. Currently it is running some eight pumps and three airstone devices in my tanks and I've had to put valves on my two ten-gallon tanks to keep it from blowing the water out of the tank. Great blast - I just had to learn to control it. With a pond your size I see no problem.

No,This Float Starts The Pump When The Water Reaches AFull Level, Called Normally Open Circuit. You Want A Float That Shuts Off The Pump At A Full Level And Starts When Low Level, Called Normally c

It will work fine, but because it uses a water hose to create the vacuum effect, you might have to remove some water from your pond after you vacuum.

I would be more concerned with sizing the pond pump to correspond with the maiximum capability of the filter. You need to make sure that the maximum flow will not exceed the limits of the filter.

depends how small of a pond really. These are all rated at gallons/minute in water distribution.....so you can look at each pump from that perspective....I use this one in a fountain that needs to shoot water up the tube four feet high...it does it easily.....:-)

I have a 5.5 gal. and it works. You do have to prime it first. Just tip it to the side until it starts and then you can keep it at any angle. Be careful not to go over the line or the battery compartment will get water. Also, be careful of nosey fish. Mine always have to see what I'm doing. If they get sucked up, they will go into the impeller. I rigged up a screen so I didn't suck up the smaller fish.

yes do run a pond pump i use one the other day to empty a fish pond with a 6oo watts pond pump
