Frequently Asked Questions
Common questions about specification, installation, and use.
It is a submersible pump with long cylindrical shape, designed to work inside narrow tubular wells. Named 'stick' or 'palito' due to its slim long shape that descends into small-diameter wells.
Depth depends on the performance curve and flow demand. Check the curve table in tech docs — higher power (1.8kW here) = deeper reach.
The ATSM2 line is specifically for tubular wells. For water tanks use our Submersible Vibratory line.
We recommend annual preventive inspection by a qualified technician. Warning signs: flow drop, abnormal noise, breaker tripping.
High power motors (above 1kW) need 220V for safe stable operation. At 127V the current would be too high.
