WAYNE VIP50-1/2 HP Reinforced Thermoplastic Submersible Multi-Use Pump - Up to 2,500 Gallons Per Hour - Heavy Duty Multi-Use Pump

I've had a smaller version of this pump by the same manufacturer for several years and it is amazing, so I ordered this for a larger project. At zero head pressure it delivers, through a 5/8" hose 50' long, without any fittings or spigot, 5.4 gallons in 60 seconds. Or about a gallon every 11 seconds, which is pretty quick, and works well for watering a garden. It provides just enough pressure to get bubblers to work, but isn't anything like municipal water pressure. Due to the low power consumption, you don't need a heavy extension cord to run it. We had a cold snap and it was frozen in ice (in my rainwater collection tank) for two days before it thawed out enough to test it. No problems. Another super product from Wayne.

My husband is please with the quality and the performance of this pump.

Really fast for a standard garden hose. If you are using this to drain a hot tub - you can expect this to be twice as fast as a 1/4 Rigid like I was using. It is also self priming which has saved me a lot of headache.

Played with this pump yesterday to empty my waterfall pond which is full of leaves and decayed leaves which makes mud. Previously, I used a standard submersible pump with the grid bottom to take in the water. However, the bottom grid would get quickly clogged with mud and leaves. This vortex pump is much better although still can get clogged with leaves. The impeller creates a strong vortex in a chamber beneath it which acts like a tornado sucking in water through the intake port and throwing it out the output port. The impeller never gets clogged. If the output port gets clogged for whatever reason, there is an over pressure release valve. If the intake port gets clogged, the chamber becomes dry and the impeller just spins to no real harm it seems (at least for a short period of time. The motor does have over temperature protection). The impeller is solid thermoplastic and should never wear out since it does not need rubber fins that rub against a pump chamber’s wall like normal pumps.This system works beautifully on dirty water and can pump a lot of water (although at low pressure) but the small 1" intake port can be blocked with leaves. The port needs to be small compared the chamber volume to maintain the vortex. The other problems are that the pump is very quiet so you can’t really tell if the intake port becomes clogged unless you look at the output hose (no water). The other problem is that the vortex is actually quite strong and it will suck itself to the bottom if the pump sits on a soft surface like a rubber mat (in spite of the feet). You can remove the bottom of the vortex chamber if the output port or the chamber becomes clogged although this is much less likely than the intake port becoming clogged. While the starting water level must be above the top of the output port for maximum flow, it will pump down to 3/8” and pass up to ½” material. I’m thinking some kind of stand might be used to keep away leaves and prevent the thing front sucking itself to the bottom although the pump down depth would increase. So far great improvement over standard submersible pump or centrifugal pump for that matter. This pump costs about 50% more than a standard submersible pump but works much better and is a name brand (Wayne). Other vortex pumps are much more expensive and largely meant for commercial use. The pump comes in three sizes although the price difference is not great so I bought the largest. Strongly recommended over standard submersible pump if you have dirty water. None better for the money.

This pump works very well for tankless water heater descaling maintenance. With approximately 2 gallons of combined descaling solution and water in a 5 gallon bucket I placed pump inside bucket. Hooked washing machine hoses up. Very nice feature with the inline power switch on the cord. Pump runs Very Quiet .Do this every year. Ran for an hour straight with no problems. Highly recommend.
