Pedestal pumps transfer or continuously circulate liquids through a system. These pumps are belt or pulley-driven. Different pump housing materials suit various liquids and can handle potable water if NSF-certified. 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.
