    I’m looking for a new shallow well jet pump, probably 1 hp. Do most cast iron pumps have built in protection in case the water intake runs dry?

    I want to get a pump that will provide long reliable service. I’d appreciate recommendations for quality pump brands, or what to look for in a pump. I’ve read about some Gould, Red Jacket, Red Lion and Dayton pumps, but I don’t know enough to judge quality. I understand the specifications for gpm/well depth/psi, and maximum psi, and I assume that higher gpm/max psi may indicate a better pump, but the gpm/max psi of all the 1 hp cast iron pumps are fairly close. Pump prices, however, can vary significantly.

    Goulds is pretty good.

    I can't comment on the run dry protection part of it, I don't deal with that a lot. I did run across something that would not let the pump run hot, but I'll have to look it up.

    Goulds; Sta-Rite; Berkley all build quality pumps. Install a low pressure cut-off pressure switch or even better a Digital Pressure Switch
    EPS15/9 from http://www.cyclestopvalves.com/index2.html. Either will shut the pump down when it looses prime.

    I installed an EPS15/9. Looks very well made. Heavy duty. Works fine.

    The EPS15/99 also has low pressure cut off to protect the pump from a dry run condition.
