Cast Iron Sump Pumps Are Recommended.
Why Are Cast Iron Sump Pumps Recommended?
Cast iron sump pump are a great choice. Here are the reasons for considering cast iron housing.
✓ Cast iron is strong and is not likely to crack or break, especially if it is class 25-30 with 25000# tensile strength.
✓ Cast iron, though submersed in water, is epoxy coated to retard corrosion.
✓ Cast iron is heavy; therefore the sump pump will not move in the sump pit as easily during heavy duty pumping.
✓ Cast iron dissipates heat readily. Heat dissipation capability is important for those submersible sump pumps that pump continuously for long periods of time. A sump pump motor that gets too hot will be shut off because of thermal protection against overheating.
✓ Cast iron will not wrap thus ensuring all moving parts will remain in alignment and function as intended.
What Characteristics Make Cast Iron Housing A Good Choice For Half HP And Greater Sump Pumps?
✓ Strength makes it strong enough to withstand heavy duty pumping
✓ Heat Dissipation keeps it from overheating during continuous pumping.
✓ Weight keeps the sump pump stable in the basin. some pumps weigh thirty-nine pounds.
✓ Durability encourages failed part replacement.
✓ Cost higher than thermoplastic is acceptable because heavy duty pumping needs justify more cost.
