They pump up to 5.3GPMgpm and up to 60PSIpsi and can run dry without damage. Available in 12 or 24VDC, . The 5000 series features a sealed switch and motor shell to keep incidental water spray from damaging the pump. NOTE: While it is a sealed motor and switch, all SHURflo surface pumps are designed to be installed out of the elements in a building or shed. Here are the models:
Model 5040-2301-D011 (up to 4.0GPM, 55PSI)

Model 5050-2301-G011 (up to 5.0 GPM, 55PSI)
Tips when installing a SHURflo surface pump:
To prevent debris from entering the pump and harming it, you should install a Shurflo strainer. Be certain to also clean out the strainer as needed.
The fittings are all tapered thread, so do NOT over-tighten these. Thread by hand until snug and then perhaps another 1⁄4 turn – that is it, not more is needed. Also, no pipe tape is needed on the pump fittings. These are tapered and do not need tape, which could find it’s way in the pump head causing damage.
When winter is on its way, be sure to winterize your water system, especially surface pumps. This can be done by adding a food grade anti- freeze or removing the pumps for the cold season. Pumps with water in the head or the line can freeze and then expand. This can crack the pump head or line causing significant damage. An ounce of prevention is easily worth the effort required.
