Will the pump be damaged if ran without pumping anything, like when it finishes pumping water out of a barrel and keeps running while unattended? Some impellers are made of rubber and they make contact with the pump's housing and those types can be...

I am not sure if this pump has "rubber impellers" or "plastic impellers" I do know that the first time I used this pump it was pumping water great, I left if over night and when I came back the next morning the pump was burned up. I believe this was from pumping air.

Manufacturer inform that can be run continuously but always entering water to the pump (if NOT the pump suffer or be susceptible to damage). My particular opinion,must be run intermittenly.

No. Don't use anything that is gritty or has beads or granules (like strawberry). It runs the mechanism & jams the pump. If that happens, just buy a replacement pump.

This vacuum does not rely upon the pump at all. It does not work using the pump, electricity or battery. It is attached to a regular garden hose and the pressure of the water is what pushes the debris into the bag. I love this product because of all these reasons. Also, with the help of a bag well known and made by Handy, who posted a great review on Amazon, it works much better. Need the instructions and pictures of how Handy made it I can send them to you. I think the pictures are now also posted on Amazon.

As a general rule, no pump likes to run dry. The water cools and may also help with lubrication. Sucking a little air might be OK but running dry is not, at least in my book, and that goes for any pump unless they expressly say it is. If you fix your leak, power on and and it pumps water without leaking around the shaft, you're probably OK.

oops on the last answer. The engine is shipped without oil. The pump doesn't need any. Unless you started the engine without the garden hose connected and on, you shouldn't have had a problem. I believe that it comes with a 1 yr warranty. If it is the pump and you didn't run it dry, it should be covered. If you ran the engine without oil, you are really out of luck.

No. The pump COULD be running. The bacteria will disperse more slowly without the pump, but it will be effective either way.

Sounds like what happened to me. I disassembled the pump with ease and one of the shafts was broken on the rotor. Easy to replace. Good luck.

I restricted the flow on the 2 pumps I bought, it did not damage them. The pump did not work any less just a slower flow of water.

If you read my reply, I said that there is a little motor with it. Sorry - thought that was clear. Note: a motor is not the same as a pump; however, it does move the water around, as in agitate.

Ron, If it's not primed, it will burn out the pump pretty fast. You might look for a pump that does not have to be pre-primed.They cost quite a bit more, but they do make them. Instructions on this pump say, the pump gas to be level or below the hose that leads out of holding tank.

The old pump that I replaced had to be filled. I filled it with oil but it still didn't work. The new had no place for oil and appears to be sealed. I have run it for 30+ hours and it is still working great. I still question if it could be filled but assume that it doesn't need oil out of the box.

The owner's manual says "Do not allow pump to run dry.The shaft seal depends on water for lubrication.Operating the pump without water will damage theshaft seal and cause pump failure." on page 4.

I cannot find any need to oil the pump as it appears to be a completely sealed unit. Have been using for a couple of months without a problem.

The motor is magnetically coupled to the rotor so when something thicker was inside the pump head I think it would slip. As stated previously this pump must be primed which could be difficult with something thicker. I have never pumped anything but beer through mine.

Yes, you do have to pump the handle to keep the pressure up in the sprayer but you will have time between pumps that the spray will come out without pumping.

We have had great success with our materials in this application vs. conventional rubber I have attached a link to our run dry data. The material itself as stronger wear characteristics and excellent hydrolytic stability however we do recommend that our customers change yearly and carry a spare in case if fouling. Hope this helps. https://www.gcsmarine.com/content/impellers/impellers
