3.5SDM 0.37KW Deep Well Water Pump Agriculture Irrigation System Pump for Home Use

1.For water supply from wells or reservoirs.
2.For domestic use,for civil andindustrial applications.
3. For garden use and irrigation.

Product description

This robust submersible pump solution is engineered for comprehensive water extraction across multiple environments. The system excels in drawing water from boreholes, deep wells up to 80m, and natural reservoirs with sand content tolerance of 0.25%. Its versatile design accommodates domestic water supply, agricultural irrigation systems, and industrial process water delivery. The thermally optimized motor maintains reliable performance in fluid temperatures reaching +35°C while operating within 4" diameter confined spaces. Customers may select between rewindable copper-wound motors or permanently sealed variants, available in both three-phase (380-415V/50Hz) and single-phase (220-240V/50Hz) configurations. Standard packages include either conventional starter control panels or advanced digital automation modules featuring dry-run protection. Optional upgrades comprise specialty mechanical seals for abrasive environments and custom voltage/frequency sets (including 60Hz variants) for global deployment. The stress-optimized casing architecture ensures longevity in continuous duty cycles across residential, municipal, and commercial installations.

FAQs

1.Q:Can it handle sandy water? Max sand content?
A:Wear-resistant stainless steel impeller can tolerate sand content <0.25% (pre-filter required)

2.Q:Can it handle hot water?
A:Maximum fluid temperatureup to +35℃
3.How to determine stages based on well depth?
A:Each stage adds 8-12m head; Total stages = (Depth÷10) + safety margin
