A normal mud hog, would likely tear it up - it is not designed to pump sand. you would need to rent a grout/slurry pump for that, and make sure there is a lot of water in the well (shooting a hose down into it) or you could still plug it up easily with sand.

However - a couple of other thoughts - first, a centrifugal pump will pull effectively from a maximum of about 20-22 feet and more commonly about 15 feet, so you would likely not be able to pump down to the bottom of the well if it is pumping dry - if it retains 5-10 feet of water in the bottom, then likely will work. A positive displacement (piston) pump can pull about 22-25 feet of suction - but most contractors would not use one to lift sand because it will chew it up, so you likely need a jet lift or air lift pump, or use a sand bailer to clean the well.

More seriously - WHY is it sanding in - likely you have a corroded out screen or failed gravel pack which should be replaced. Keep pumping the sand out and you may eventually form a sinkhole around the well.

Or perhaps your well is going dry and does not have a bottom plug, so you are getting sand "boils" in the bottom as the water comes into the bottom of a nearly dry well.

Plus - even if you get the sand out, without fixing the well it will just sand back in again and ruin another water pump - so you need to get a Well and Pump contractor in to rehab your well and install a screen and gravel pack to stop the sand infiltration - then using his own pump flush out the riser pipe and all the piping so sand in the pipes cannot flush into the house or back down into the well riser), then install the new pump. Ditto to flushing any pressure or surge tank in the system.
