I’ve spent enough time around wellheads and test benches to know when a pump line quietly wins the room. The 135QJB Deep Well Submersible Pump has that vibe—no drumrolls, just competent engineering, consistent curves, and the kind of OEM flexibility buyers quietly ask for.
Origin matters: this series is built in No. 6 Xingyuan Road, West District, Lincheng Economic Development Zone, Hebei Province. The factory undertakes OEM processing and can design non‑standard motors and pumps to spec. Implementation standards: GB/T 2816‑2014 (well submersible pump) and GB/T 2818‑2014 (well submersible asynchronous motor).

Across agriculture and municipal supply, there’s a clear shift toward higher efficiency rotodynamics, plus smarter protection modules. The 135QJB Deep Well Submersible Pump rides that wave: trimmed impellers for duty-point matching, optional 316 SS wet ends for aggressive water, and sensible protection (dry-run, overload, surge). Many customers say their energy bills nudge down simply by tightening the duty point—unsurprising, but always nice to hear.
| Bore size | ≈135 mm series (for wells ≥6") |
| Flow (Q) | ≈ 30–120 m³/h |
| Head (H) | ≈ 60–280 m |
| Motor power | 7.5–75 kW (50/60 Hz options) |
| Voltage | 380–660V (others via OEM) |
| Materials | 304/316 SS, CI bowls/SS bowls, silicon‑carbide seals |

| Efficiency (bench) | Up to ≈72% at BEP (ISO/GB acceptance) |
- Farm irrigation and pivots; - Municipal/estate water supply; - Mine/dewatering; - Geothermal wells; - Industrial make‑up water; - Emergency standby for fire tanks (with proper controller). In practice, the 135QJB Deep Well Submersible Pump shows up where reliability beats theatrics.
Impeller trims for exact duty point, 316 SS wet‑end packages, special voltages, cable length/types, duplex bearings, sand‑resistant stages, and control panels with soft start/VFD compatibility. Frankly, that last one—VFD pairing—saves more energy than most people expect.
| Vendor | Strength | Trade‑offs |
|---|---|---|
| WellPump ACT (135QJB) | GB/T compliance, OEM flexibility, balanced cost/performance | Lead time for non‑standard builds ≈2–4 weeks |
| Generic Import | Low upfront price | Variable QA; sparse test data |
| Local Fabricator | Fast service response | Limited head/flow envelope |
Bench at 50 Hz (acceptance GB/T 3216 Grade 2): Q=80 m³/h, H=160 m; shaft power ≈30 kW; pump η ≈70%; PF ≈0.85; vibration
Conforms to GB/T 2816‑2014 and GB/T 2818‑2014; hydraulic acceptance per GB/T 3216 or ISO 9906. IP rating per IEC 60529. Ask for routine test reports with every shipment—seriously, it’s worth the two minutes.
Bottom line: if you need a deep‑well workhorse with proper documentation and OEM options, the 135QJB Deep Well Submersible Pump is an easy shortlist pick.
