The difference between the single and twin impeller is the total head and water flow. A twin impeller can pump a higher total head than a single impeller but a reduced water flow. The single impeller would have a higher water flow but a lesser total head. It is all dependant on your unique requirements.
These pumps have a cast aluminium impeller, cast iron diffuser, cast aluminium pump body, metal (not plastic) delivery outlet caps, as well as, bolt on replaceable suction and discharge ports. All these features ensure the durability of the pump and are easily replaced if damaged.
