What is the Max Suction Lift? Also, what is the flow rate at 20ft head?

I believe it is 3.5 gallons per minute. I am on holiday and do not have the specs with me. I was very pleased with this pump.

If you go look up the spec's, (I was looking on Grainger.com) the almost exact same pump(& same motor) is spec'd to pump 19 gpm @60 ft of head. This would likely due 15-19 gpm at 60 ft of head. Its max ft of head is 106 and a max suction lift of 26 ft (as stated on the product description). I wouldn't push these limits though. These type pumps should run between 1-2 hours under load before fully draining the fuel tank.

If you mean "Can this pump lift water 50 ft?" then the answer is No. The theoretical maximum is 33 ft, and that would require a vacuum pump. The pump inlet needs to be no more than 3 ft above the water level or the pump will suck nothing. If the pump inlet is close to the water, this pump will pump the water up 120 ft.

In my review I added this info about the pump:On the box it shows these numbers for performance (actually on a bar graph)at 0 vertical lift you get 2400gphat 5 foot lift 2000gphat 10 foot lift 1400gphat 15 foot lift 900gphIt doesn't show higher than 15 foot, so I doubt it's recommended for higher.

Not sure of the top range, tested mine at 20+ ft as well.. worked flawlessly.

Technically, that's 3 feet above its rated maximum head (which is 21 feet). That doesn't mean it won't work for that application. It would just be less efficient than a larger pump with higher head rating. It also depends on how often the pump will run. Forcing the pump to push a higher column of water than its rated would probably make it wear out sooner.

Sorry to say I don't remember. However, the flow rate is quite good as it comes.

Can't say for sure but it does flow all that is supplied. It is a nice unit. The Manufacturer should be able to tell you the max flow rate.

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

The flow is not adjustable. The size of pump depends on the lifting requirement for your pond flow.

Technically, it is not lifting but pushing - there is a limit to what a vacuum pump can pull, so I think this type of pump can push more - of course this type of pump also has a limit. I use it to reach into my sailboat bilge located in its shoal draft keel, then up to the lower edge of the hatch opening & out. I need to extend my whole arm down there to touch bottom with my shoulder a few inches below the hatch opening, so I estimate the total vertical distance is about 3 feet 4 inches. This unit easily pumps water up that height, and still pumps it out at a healthy velocity. It's also the only pump I have found that can fit into that very small space.

I'm not sure what the max rate is - but its a lot - wide open is essentially just allowing the tube to flow freely - not sure why you'd need an emitter if you want that much water - just poke holes in the supply tube... My frustration is at the other end of the range - I wish they could provide an even slower drip.

The chart on the side of the box says that at 0ft, it goes 120gph, 1ft is 85 gph, and 2 feet is 45gph. So, you're talking about a pretty slow flow rate at 18". It doesn't say if that's vertical lift or just the distance of the tubing, but the effectiveness will depend on what you're using it for.

This unit is the best for close contact and is not made to reach 15 or 20 ft at a mist, spot spray will reach out but not but not always the best idea. This is my option and i use this pump a lot. Hope this Helps. Regards

Use the manufacturer's recommendations to determine which is best. How high will the lift be, what is your water pressure, etc.

It depends on what you want it to do. All pumps not only have gallons per minute rating but a lift rating. If you want it to supply a waterfall or move water to a height above pond level you need to check the rating. Otherwise it is a reliable pump and I have had one supplying a bird bath from a below ground container and it moves a lot of water and I must use a diverter to cut the flow. I have a waterfall close by and it would not move enough water three feet high so I use a bigger pump for this feature.

Would not recommend it. The max lift according to the manufacturer is 200 ft. You need to go to 3/4 or 1 hp.
