Why it matters
The 91501 is a 1/2 HP cast iron utility pump. Superior rates it at up to 4,200 GPH and 25 ft of lift through a 1-1/2 in NPT discharge, and it passes solids up to 1/2 in.
The split capacitor motor is thermally protected for continuous duty. Superior says it can work as a sump pump with an optional float switch.
Who it's for, and who should skip it
Good fit if
- Large flooded areas
- Owners who want cast iron
- Conversion to a sump pump
Look elsewhere if
- Sewage or grey water with solids
- Unattended running on manual models
Pros and cons
Pros
- Cast iron
- 1/2 in solids
- 1-1/2 in discharge
Cons
- Heavy
- Manual out of the box
- Float switch sold separately
Limitations to weigh
- Manual pumps run only while switched on; stay with the pump so it doesn't run dry.
- Rated flow is at little or no lift; through a garden hose or up a stairwell, expect much less.
