1100GPH Bilge Pump with Float Switch & 1-1/8 Inch Hose Kit – High-Flow, Fully Submersible Pump, Automatic On/Off Switch, and Durable Corrugated Hose for Boats, Yachts, Dinghies

The media could not be loaded.This pump and switch combo with the coupon I found was pretty much the cheapest decent quality looking set I could find.I need it not for marine applications but as a way to drain my dehumidifier tank in the basement. Otherwise it overfills.I haven’t set that up yet, but this should work more than well for it from what I can tell.The pump seems solid, it is a centrifugal pump with 3 blades. Has good power. And self primes (As it is a submersible pump.)One thing I don’t like is that it doesn’t have some type of filter medium on the input but maybe that is simply because it would be likely to get clogged and that would be more risky? Who knows.Anyways it is a 12v pump the float switch however is supposed to be compatible with 12, 24 or 36v pumps up to 20amps.I don’t know the amps the pump draws while running I will try and figure that out later and update if I do.Anyways though I did run a test of pumping out a 5 gallon bucket that was filled to the brim. (That is a bit more than 5 gallons but because the pump can’t drian it all the way it is close enough.)It took 21 seconds to drain a little more than 5 gallons.60 minutes x 60 = 3,600 seconds.3,600s/21s (Time to drain 5 gallons) = 171.43 units × 5 gallons = 857.15 gallons per hour.So the pump in my setup moved approximently 860GPH. Not the 1,100.However the is a caveat to this as the ratings on these pumps are based off the absolute ideal conditions.In the case of a pump the output line will need to be smooth and short, the wires will need to be securely attached to a power supply and short, no additional switches, a container that doesn’t cause turbulence while pumping and output height only slightly above the input height.In my case the water line was fairly short but it was corrugated which is HORRIBLE for flow rate.My wires were not securely attached, they were on the longer side because of going through the float and there was the float switch instead of a direct attachment.Additionally the container was small which could easily cause turbulence and it had a bit of elevation when pumping…So if I were to take a guess under absolutely IDEAL conditions it probably would reach the 1,100GPH.However under more realistic conditions you’ll see at least a few hundred less. However that will be true for any pump out there. That is just how things go in lab vs life.The wires look to be 14 or 16g tinned copper which is good for corrosion prevention.The output hose is a barb connector at about 29mm, or 1.15in. The line for both the switch and the pump is about 3ft long.The noise level is fine. Not anything too loud while running, can easily be talked over. If in another room I doubt you’d hear it. The water splashing is much louder.I think that is pretty much it, hopefully it’s helpful and I will update in the future if there is new things to say. [...]
