Frequently Asked Questions
How deep can the 4SP5 Series pump extract water from?
The 4SP5 Series series delivers water from boreholes up to 369m deep through 4" diameter wells. The multi-stage design ensures stable pressure even at maximum depth.
What is the difference between single-phase and three-phase models?
Single-phase (M suffix, e.g. 4SPM5-4) runs on standard 220-240V household power. Three-phase models run on 380-415V industrial power for higher efficiency. Both deliver the same hydraulic performance.
How do I choose the right model for my well?
Use the filter above to set your required head (depth + elevation + pipe friction) and flow. Choose the model that operates near the best efficiency point of the curve. Contact us for professional sizing assistance.
What material is the pump made of?
All ALFAGRAND deep well pumps feature AISI 304 stainless steel construction for the pump body, shaft, coupling, and impellers. This ensures excellent corrosion resistance and long service life in groundwater applications.
What is the warranty period?
Standard warranty is 3 years. Extended warranty options available for OEM/ODM orders. Warranty covers manufacturing defects under normal operating conditions.
