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.
