When you spend time around drillers and ag managers, one name keeps popping up for deep columns and sandy water: the 200QJR Deep Well Submersible Pump. It comes out of No. 6 Xingyuan Road, West District, Lincheng Economic Development Zone, Hebei Province, and, to be honest, the factory’s willingness to tweak details for oddball wells is what first caught my eye. They undertake OEM processing and build non‑standard motors and pumps to spec—rare and handy when geology doesn’t play nice.
The 200QJR Deep Well Submersible Pump is a multistage, radial/partially mixed-flow unit for 8-inch wells (≈200 mm casing). It’s built around GB/T2816-2014 for pumps and GB/T2818-2014 for submersible asynchronous motors—those are the yardsticks in this corner of the world. In practice, that means predictable curves, tight leakage limits, and motor thermal performance that doesn’t drift in July heat.
| Parameter | Typical Range/Value |
|---|---|
| Well casing size | 8 in (≈200 mm) |
| Flow (Q) | ≈25–160 m³/h |
| Head (H) | ≈60–420 m |
| Motor power | 22–110 kW (50/60 Hz options) |
| Voltage | 380/400/415/460/575 V |
| Efficiency | Pump peak η ≈ 73–80%; motor η ≈ 88–92% |
| Materials | 304/316 SS bowls & shaft, cast iron/CF8M options, SiC mechanical seal, NBR elastomers |
| Sand tolerance | ≤0.01% by mass (typ.) |
| Protection | IP68, Insulation Class F |
Irrigation districts (pivot and drip), municipal backup wells, mining dewatering, geothermal test holes, and livestock water supply. One Hebei farm pushed a 160 m³/h model at ~180 m TDH during peak season; another customer in a limestone belt reported stable drawdown despite fines—surprisingly calm amperage trace, too.
| Vendor | Strengths | Watch-outs |
|---|---|---|
| WellPump (200QJR) | OEM flexibility, solid GB/T compliance, fast spares lead time | Documentation style varies slightly by batch |
| Brand A (EU) | Premium stainless and coatings, wide distributor network | Price premium ≈15–25% |
| Brand B (US) | Great VFD support, strong documentation | Longer lead times for 60 Hz deep heads |
Mining pit, Inner Mongolia: a 90 kW set ran 24/7 for 11 months; post-pull inspection showed 200QJR Deep Well Submersible Pump wear rings within tolerance. Municipal standby, coastal city: 316SS build resisted chloride stress; operators liked the quiet start on soft-starter. Not perfect—one ag install saw seal wear from silty surge during flushing. After adding a sand shroud, amperage stabilized.
Conforms to GB/T2816-2014 and GB/T2818-2014; factory typically maintains ISO 9001 quality management. CE available on request. For custom builds (non-standard heads, metallurgy, cable lengths), WhatsApp: 17855846335. I guess the standout is how quickly they iterate small design tweaks without blowing up your budget.
