How to Choose the Right Self-Priming Pump
Selecting the right self-priming monoblock pump depends on your building height, suction depth from the sump/line, and overhead tank volume:
Building Height & Head Reach
- For 1–2 storey houses (up to 20m head), Nira 50 (0.5 HP) provides ample pressure and flow.
- For 2–4 storey buildings or apartments (up to 32m–38m head), choose Nira 100 (1.0 HP) or Nira 10V.
Suction Depth & Lift
- Standard shallow sumps and ground-level municipal tap lines (up to 5m depth) use Nira 50 or Nira 100.
- Deep sumps, borewell pits, or long horizontal suction runs (up to 15m suction lift) require the Nira 10V deep suction pump.
Tank Capacity & Filling Speed
- A standard 1,000-liter rooftop tank fills in ~40 minutes with Nira 50 (1,600 LPH peak) or ~25 minutes with Nira 100 (2,500 LPH).
Thermal Overload Protection (TOP)
- All Nira models include built-in bi-metallic TOP sensors that automatically cut off power during overheating or locked-rotor conditions, protecting the 100% copper motor.
Airtight Suction Piping
- Self-priming pumps require airtight joints on the suction pipe to establish and maintain vacuum.
- Always use 25mm (1") rigid PVC or GI piping with Teflon tape on threaded joints.
