Before the shortlist
The first four answers do most of the work
A useful ranking starts only after the constraints specific to this market are clear.
- 01
What are the measured inflow and total dynamic head through the real discharge path?
- 02
Will the basin fit every pump and switch with clear travel and useful cycle volume?
- 03
Which failures must the backup cover: primary fault, power loss, high water, blocked discharge or lost connectivity?
- 04
Who will commission the pumps, battery, check valves, alarms and permit or inspection requirements?

Market language
The terms a useful comparison should define
- Total dynamic head
- Static vertical lift plus pipe, fitting, valve and outlet losses at the intended flow; it is the useful point on the pump curve
- Cycle volume
- The water moved between switch-on and switch-off levels, which affects run time, starts per hour and basin fit
- Combination system
- A primary and backup sold as one assembly; it may still exclude the battery, alarm module, final check valve, discharge work or installation
- Conditional runtime
- Backup time under a named battery, head and duty cycle, not a promise for an unknown storm, aging battery or restricted discharge
