从China供应商批量进口3'' 1hp High Head Deep Well Submersible Pump

The 3'' 1HP High Head Deep Well Submersible Pump from Wenling Ruiyuan Pump Manufactory is a centrifugal submersible unit built for lifting water from significant depths in boreholes and deep wells. It pairs a 1 horsepower (approximately 0.75 kW) motor with a 3-inch discharge outlet, a configuration common in agricultural and small-scale municipal water systems across China. The pump uses a multi-stage centrifugal impeller stack to generate the high head pressure needed to push water to the surface from depths that exceed suction-pump limits. Its submersible design keeps the motor cooled by the surrounding water, eliminating the priming issues and cavitation risks that plague surface pumps in deep-well applications.

Typical construction for pumps in this class uses 304 or 316 stainless steel for the impeller, diffuser, and pump body, with a cast iron or stainless steel motor housing for corrosion resistance against groundwater minerals. The motor is usually oil-filled or water-filled for cooling and lubrication, with a standard IP68 rating for continuous submersion. Mechanical seals of silicon carbide or ceramic faces separate the motor chamber from the pumped fluid. Wenling Ruiyuan's listing does not specify exact metallurgy or seal grade, so buyers should request material certificates and seal specifications before ordering. Standard voltage for this power class is 220V single-phase or 380V three-phase at 50Hz, though 60Hz variants exist for different markets.

This pump suits rural residential water supply, smallholder drip and sprinkler irrigation, livestock watering, and light industrial processes where mains water is unavailable. Buyers importing from Wenling in Zhejiang Province should confirm whether the motor is single-phase or three-phase, as this affects installation requirements and running costs. The high-head design implies a narrower operating curve at maximum flow, so matching the pump to actual well depth and required flow rate is critical to avoid motor overload or premature wear. Request a performance curve (flow vs. head, flow vs. efficiency) from the supplier to verify suitability for your borehole.

Wenling Ruiyuan Pump Manufactory is located in Jin'ao Industrial Area, Wenling, Taizhou, Zhejiang Province, China (postal code 317525). The supplier is classified as an imported-tier manufacturer on this platform, with a harbor trust tier. The listing shows a response rate of 0.00% and zero average response hours, which strongly suggests the supplier has not engaged with buyer enquiries through this channel. Buyers should treat direct communication as untested and initiate contact early to gauge responsiveness.

The supplier profile provides no verified factory size, year of establishment, annual revenue, export license details, or named client references. No ISO certificate numbers, test reports, or third-party audit results are displayed in the source data. The address places it within Wenling's established pump manufacturing cluster, a region known for submersible and surface pump production, but geographic concentration alone does not verify output quality. Buyers should request a factory profile, business license, and any available product test data before committing to an order. The lack of response history means due diligence is particularly important.
