Straight Centrifugal Pumps
Straight centrifugal pumps have an intake connection in-line with the impeller's eye and shaft. These pumps use centrifugal force to move water through systems for various applications. They require regular priming or for the liquid source to be located above the intake. The pump's head and flow performance increase as the HP rating increases. Different housing materials can handle fluids for various applications. Cast iron is more cost-effective but less corrosion-resistant than stainless steel, bronze, and aluminum. Aluminum resists corrosion better than cast iron and is lightweight. Bronze is corrosion-resistant and can handle potable water if NSF-certified. Stainless steel resists corrosion better than other materials and handles a wider range of liquids, including potable water if NSF-certified.
