Irrigation & Water Pumps from China: Submersible OEM Sourcing
1 resources tagged with "Irrigation Water"
Water-handling hardware for irrigation from China centers on submersible borehole pumps — 4-inch and 6-inch bodies with stainless impellers, carrying CE, RoHS, and IP68 ingress ratings, with NSF/ANSI 61 available for potable-water use. MOQs are low for this category (often around 50 units), but the quality gap shows up in impeller material and motor winding, where a cheap factory substitutes lower-grade stainless that corrodes in mineral-heavy water. We verify material grade and run a head/flow test before shipment.
This covers pumps and water-delivery components for irrigation and borehole supply. The pitfall is buying on price without confirming the stainless grade and the motor's IP68 seal integrity, which determine whether the pump survives a season underwater — so we test head, flow, and seal on samples.

FAQ
What MOQ applies to OEM submersible pumps from China?
Submersible borehole pumps often have a low MOQ, around 50 units, because the castings and motors are standard. Custom branding, voltage, or NSF/ANSI 61 potable certification can raise the practical minimum.
Do I need NSF/ANSI 61 for an irrigation pump?
Only if the water contacts drinking-water systems. For pure agricultural irrigation, CE, RoHS, and IP68 are usually enough; specify NSF/ANSI 61 explicitly when the pump feeds potable supply, since it is an optional add-on.
