*SP30-17* is a submersible borehole pump model code.
*What it means:*
- *SP* = *S*ubmersible *P*ump. It goes inside the borehole underwater.
- *30* = Max flow of *30m3/hour* ≈ 500 Liters per minute.
- *17* = *17 stages*. Each stage adds pressure. More stages = can pump deeper/higher.
*Typical Specs:*
- *Power*: 7.5HP to 11HP. Runs on *380V 3-phase* only.
- *Watts*: ∼5600W to 8200W running. Needs 30kVA+ generator to start it.
- *Head*: 140m to 180m max. Can pump from very deep boreholes.
- *Pressure*: 14 to 18 bar.
- *Borehole size*: Needs 6-inch or 8-inch casing.
- *Body*: Stainless steel to resist rust.
*Best For:*
Big jobs. Estates with 50-100 flats, hotels, schools, hospitals, and farms. It can fill a 10,000L tank in about 20 minutes.
