Jon, it is possible that you will pump less sand if you pump slower. It is possible to throttle a pump in a controlled manner. You might read some description of the effect of pumping more slowly in this thread despite some very significant differences: https://terrylove.com/forums/index....dvice-please-borehole-supply-in-the-uk.61806/
If you have occasion to replace your pump in the future, you might opt for a slower pump. If you are watering a few head of cattle and running a house, your needs will not be that great. If you are watering acres of iceberg lettuce, you will be pumping a lot.
