Does this pump have some kind of speed control? I guess i am just concerned about a stuck mash if it is pulling to hard. Thanks!

It does not. Typically you will see people putting a ball valve on the out put side to allow you to control the flow rate. You should be able to find example pictures on the Internet hope that helps

It does not have a speed control. You would mount a ball valve on the output side of the pump and control the flow with the valve.

A ball valve can attenuate the output of your pump, but do not starve the pump by constricting the input.

This pump has no speed control but flow control when installed a ball valve at the outlet. It does not matter if the mixture gets stuck. The pump can stop completely with the engine running without problems. I've closed the ball valve many times, or I've reduced the flow without problems. The connection between the pump and the motor is magnetic and non mechanical.

No you must put ball valves up-line or down-line of the pump to limit its speed.

No it does not have a speed control. However, this is a very good pump. Stand by, and pay attention!!!

Not electrically. Put a valve on the out side of the pump to control flow rate, works great.
1856944
No. You control flow by limiting the outflow. I have a valve on the output and the pump can run even when it's completely closed.

Hi: I bought the pump to use with an HO scale river lock on my layout. It seemed to work fine at first when I was testing things. I was able to pump about 1 quart every minute which was fine. When I put it all together the pump would work fine for a minute or so then stop or slow to just a trickle. New batteries did not help. I did not think of the back pressure and that could be my problem. I replaced it with a small pond pump. Good luck. Steve

It does NOT operate on demand. Plug it in and it runs. Remove the plug and it shuts off. As long as you have it in water the suction remains constant. Having said all that, I love this pump. My only problem is that it is sooo heavy. I use it mainly to empty my 150 gal fish tank prior to cleaning and to empty my grandchildrens' 15' swimming pool every Fall. I just attach a long hose to the pump and water my garden flowers until the pool is empty. Only once did it give me a problem and that was when I took the protective screen off the intake and it sucked up a large piece of gravel from the fish tank. Something broke inside. But my son went up to Lowe's for a little part and it was good as new. You must remember to prime it before use by putting some water in it. I would definitely buy another one if necessary but I wouldn't be surprised if it outlived me. I'm 70. I suppose that what you would use it for would determine how well it would work for you. For me it's perfect. Good luck.

When I use it for brewing I initially cycle the pump on and off a few times to get it going. The impeller is run on a magnet and not a solid shaft, so it can slip.

Bear with me for a day or two, as I'm home and the buffer is at a different location. I'll try to have an answer for you within the next two days, but whatever RPM it runs at, it does an excellent job (especially for the low cost). Also, remember that the speed you need to be concerned about, is the speed the wheel turns at the edge of the wheel/buff. For example, a slow speed 8" grinder, at the edge of an 8" wheel, the speed is the same as a high speed (3750 RPM) 6" grinder.

I purchased it to replace a single speed. The speed is what defines the flow and this you can control and set up according to your preference/needs. The purchase of this pump through AMAZON was $500 less than the price at my local Pinch-A-Penny. I had it delivered within 3 days and installed it myself. My neighbor had a "pool-guy" replace his pump and was given a pump that was way inferior and cost the same as this one. Go to the Pentair web page or You-Tube and view the video on this pump. You wont regret getting it.

Same problem. There is no "slow" speed. It goes fast and yes, it splatters.

Willee, I've got a question, yes it needs 12-15 psi at the controller, to maintain that is another issue. Some of my zones have 7 pop-ups. I called Zodiac today and got no where, they could not tell me the gpm required to keep system running or even suggest a variable speed pump for me. I understand what your saying about running high pressure for a couple hours then reducing it for eight hours, to do that I would probably need to add an automatic valve to change to side returns seeing my pop-ups wouldn't pop-up. Your thoughts. And do you own a pool with a caretaker system?

The higher up you hold it, the faster it disappearsYou can control the flow or not.Hope this helps

The flow rate through the pump and filter will be reduced a little. Consider the strain on the motor when the filter is dirty--the tiny bit of additional strain due to smaller diameter hoses will be nothing compared to that.

Not that I am aware of. I believe it's just one speed, but the whirlpool isn't very strong (you can see how fast it is if you put an ice cube in it). It mostly just keeps the water moving. The motor is removable though, so you can take it out if you'd like.

No, it has no speed control built into it. I haven't added any control to the fans that I run, I figure one more thing to break. I do have a control on a shop vac that works well that is made by VenTech, sold by Amazon believe it or not. It is rated for the amperage you are dealing with and it works very well. I would consider it, but there are very many options. Hope this helps. Dan

We like the small pump a lot. But as you discovered, the small pump comes with a non-valve controlled multi-port manifold. We use heavy weight paper binder clips and soft hose on the extra valves since we had soft hose available. We also have access to a great store 5 minutes away that sells a metal 6 port valve-controlled manifold - $5. Janet, we've had a pump returned but it appears the entire pump was either in water or left outdoors, ruining the diaphragm. What issues did you experience?

My variable speed has saved me money by only using speed that is needed. A lower HP motor is set at factory setting and you cannot make changes for peak useage. I'm very happy with my pump because one nite we had a drop in temp and when I went outside the pump was running in what it called freeze mode to protect itself from freezing. Most pool shops may not be up to date on this type of pump...... It will cost more....but I think you will save the money in the long run.

I use it all the time and with a four port manifold this pump can pull down an average residential system to 0 microns in no time. It is a little heavy but Its super tough. Ive raced a jb pump with mine twice now and the yellow jacket is just a monster. I do a lot of comercial and some residential. This pump works great at getting to a low vacuum quickly every time in any situation. It pulls down quicker than a 10 cfm jb pump I know for sure

You have kinda push down & then screw it on. There is a stop line on the pump, if u don't stop it will mess up. But mine comes loose after using it a few times but I just tighten it again.

No, this is not an automatic pump. It requires manual and or float switching to opetate correctly.
