What Are Your Pump Options for Lifting Water? | Pumps
2. Self-Priming Centrifugal Pumps. Self-priming centrifugal pumps are common, mostly for relatively low flow applications (under 1,000-gpm or so). Like any other pump, it has pluses and minuses. Maintenance is easy since the pump sits on the surface, and trash can be removed by the access ports at the side of the casing. Priming is achieved by ...
