What It Is
When your well water has sand, scale, or minerals that chew through plastic impellers — and you need real flow rate, not just trickle — the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump is purpose-built for the job. A 750 W brushless DC submersible with full AISI 304 stainless steel impeller and wet end, delivering 6 m³/h max flow from wells up to 60 m deep. The stainless construction is the matched tier for abrasive duty — sand, scale, or mineral-rich water where harder material earns its keep (sites with clean groundwater are well-served by the 3UP plastic-impeller alternative). Runs on 2-3 modern solar panels, totally off-grid, with CE and ISO 9001 certification across the whole product.
AISI 304 Stainless Steel Impeller
What sets the 3US series apart from cheaper alternatives is the impeller itself — full AISI 304 stainless steel. It sits alongside Hybsun’s 3UP750 plastic-impeller sibling — same hydraulic envelope, different construction tier sized for different water conditions. For Cyprus customers the difference matters because Cyprus well water is often abrasive. Some Cyprus wells carry sand particles, calcium scale, or hard mineral content. Stainless steel construction is the matched tier for that duty. For wells delivering clean groundwater, the 3UP plastic-impeller range is the better-fit choice — it’s purpose-built for those conditions and considerably more cost-effective. Stainless steel impellers don’t wear that way. The Hybsun 3US750-60-6C DC solar stainless steel impeller well pump’s wet end is fully stainless: AISI 304 across the external jacket, the stage casing, the diffuser, the impeller itself, the wear ring, the strainer, even the assembly screws. The shaft is AISI 431, a higher-grade stainless engineered for rotating duty. It’s the premium tier of submersible well-pump construction.
The Hybsun 3US750-60-6C DC solar stainless steel impeller well pump runs a brushless DC permanent-magnet synchronous motor with oil-cooling — the motor sits inside an external jacket made of AISI 304 stainless steel. The rotating parts use NSK industrial bearings (a Japanese brand used as a standard in continuous-duty rotating equipment) paired with an alloy mechanical seal. The pump body and motor are sealed by a double water seal arrangement that keeps the unit fully waterproof and leak-tight across years of submerged service. Inside the motor: AISI 304 shaft, graphite bearing bush, and oscillation-pad thrust bearings — all chosen for longevity under continuous-duty solar pumping.
A matched DC solar controller ships with every Hybsun 3US750-60-6C DC solar stainless steel impeller well pump in an IP65 outdoor-rated housing. The controller does maximum power point tracking (MPPT) to extract every available watt from your PV array, accepts up to 17 A input current, and reports live operating data (power, voltage, current, motor speed) on its LED display. Variable-frequency drive automatically adjusts pump speed based on PV output — full speed under bright sun, gradual slowdown as light fades.
Worth knowing: the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump’s DC controller has a built-in battery charging function. Add an optional 72 V battery bank and the controller will charge it during the day while the pump runs on solar, then draw from the battery to keep pumping after sunset or during cloud cover. For applications where continuous water flow matters (livestock, drinking water for a multi-property setup), the battery transforms this into a 24-hour pump. Battery is optional and only needed if your use case requires night-time pumping.
The Hybsun lists the full protection envelope: soft start (no inrush damage to the motor), over-voltage, under-voltage, over-current, high-temperature and adjustable speed (frequency conversion). For wells that occasionally run dry, the auto-restart is particularly useful — the pump checks again 30 minutes later instead of needing a manual reset.

Who Should Buy This
Hybsun built the 3US/3USH stainless impeller series specifically for customers who need long pump life in hard, abrasive groundwater. The Hybsun 3US750-60-6C DC solar stainless steel impeller well pump buyer profiles below cover the most common Cyprus use cases:
The Hybsun solar well pump platform is shared across all models — MPPT controllers, NSK industrial bearings, IP65 weather protection, full CE/ISO 9001 certification, and a 2-year manufacturer warranty. Models differ along three axes: construction grade (stainless vs plastic impeller material), pump architecture (centrifugal vs helical rotor), and power rating. Compare the range:
Hybsun uses the same PV sizing formula across the entire 3US/3USH series: PV array power ≥ 1.3 × the pump’s nominal rating. For the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump that means at least 975 Wp of solar panels (2-3 modern 400W panels typically). The 30% margin covers every real-world loss factor: temperature de-rating in Cyprus summer heat, dust on the panel surface, DC cable resistance, and the slow output decline as panels age.
The 3US750 controller accepts a PV string with operating voltage 72-144 V Vmp, with open-circuit voltage limited to below 160 V. That comfortably fits 2-3 panels in series — typical 400 W panels have Vmp around 36-40 V and Voc around 45-50 V each, so 2 panels in series sit around 72-80 V Vmp (Voc ~95 V), and 3 panels can run up to 110-120 V Vmp (Voc ~145 V). The wide range gives flexibility on panel selection and array sizing.
Submersible well pump flow rates always drop with depth — the 6 m³/h spec is Hybsun’s number at zero head, and your real-world flow at any given depth will be lower. Reading directly off the manufacturer’s published performance curve, here’s what the Hybsun 3US750-60/6C DC solar stainless steel impeller well pump actually delivers across the working range, plus daily output figures for a standard 6-hour Cyprus summer solar window:
“Total dynamic head” = static water level depth + pipe friction losses + vertical rise to your discharge tank. Allow 5-10m of pipe friction on top of static depth for a typical install — more if you’re running a long lateral to the discharge tank, less if the well sits close by.
To translate flow rate into your specific water demand:
For an exact sizing calculation, send CGP Solar your static water level, expected drawdown, pipe run length, storage tank height, and daily water demand — we’ll work it out against the curve and pick the right pump.
What sets the 3US series apart from cheaper centrifugal pumps is the construction grade. The 3UP series uses plastic impellers — purpose-built and ideal for clean groundwater installs, where they deliver excellent value. The Hybsun 3US750-60-6C DC solar stainless steel impeller well pump uses full AISI 304 stainless steel across the wet end — the construction tier matched to wells carrying sand or mineral content. Every component that contacts the water — impeller, diffuser, stage casing, jacket, wear ring, strainer, even the assembly screws — is AISI 304 stainless. The shaft is AISI 431, the slightly higher-grade stainless specifically suited for rotating components. For Cyprus farms and homes drawing water from wells with significant mineral content, this is what you pay the extra for — and it pays back in years of additional pump life.
Same rotating hardware quality as the rest of the Hybsun premium range: NSK industrial bearings — the Japanese brand that’s the standard across continuous-duty rotating equipment — turning against an alloy mechanical seal, with a dual water-seal arrangement keeping the pump body leak-tight across years of underwater service. Hybsun summarises the design intent in the spec sheet with the phrase “offering the longer working life”.
A soft-start circuit in the controller brings the motor up to running speed gradually rather than switching it on at full current. Every cold-start of a conventional AC motor briefly draws 5-7× its rated current — that inrush spike progressively degrades motor windings and bearings over years of daily start/stop cycles. The Hybsun 3US750-60-6C DC solar stainless steel impeller well pump’s soft-start eliminates that spike entirely, a key reason Hybsun backs the pump with a 2-year warranty for daily-use deployments.
If the well runs dry (which can happen on lower-yield boreholes during peak summer drawdown), the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump stops automatically and retries 30 minutes later. No manual reset. No burned-out motor. The pump cycles through this autonomously every time — boreholes that occasionally draw dry simply don’t pose a risk to the unit.
Typical CGP Solar project timeline: site survey and well assessment (2-5 days to schedule — we measure your well depth and static water level, and confirm the casing diameter), formal quotation (about 1-2 days), then on-site work — lowering the pump on rising main pipe with safety cable (half a day for typical residential depths), PV array and controller install above ground (half a day), and commissioning under live solar with handover walkthrough (same day). CGP Solar handles installations across all five Cyprus districts — Nicosia, Limassol, Paphos, Larnaca and Famagusta.

FAQ’s
The catalogue lists H.Max at 60 metres, and the published performance curve confirms — the curve’s y-intercept (zero flow) sits at exactly 60 m. Practical working range extends to about 50 m of total dynamic head, where the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump still delivers ~2.3 m³/h (about 14 m³/day on a typical Cyprus 6-hour solar day). Below 40 m head the pump operates in its efficient zone (3+ m³/h flow). For deeper wells (60-100m), the larger 3UP1500 centrifugal or the 3HR750 helical-rotor are better options. For shallow wells under 25m, the smaller 3US300 is more economical.
Per Hybsun’s sizing rule, PV panel power must be at least 1.3 × pump power. For the 750 W Hybsun 3US750-60-6C DC solar stainless steel impeller well pump, that means at least 975 Wp of solar panels — typically 2-3 modern 400 W modules. PV string voltage has to fall within the controller’s MPPT range: 72-144 V Vmp, with open-circuit voltage staying under 160 V. Two 400W panels in series usually land nicely in the lower half of this range; three panels in series hit the upper half. CGP Solar runs the full sizing calculation per project.
Yes — the 3US750 DC controller includes automatic battery charging. Connect an optional 72 V battery pack and the controller will charge it during sunlight hours while the pump runs from solar, then power the pump from the battery overnight or during overcast spells. For commercial sites where uninterrupted pumping is critical, this is a practical upgrade. The battery is optional, not mandatory; the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump runs perfectly from solar alone during daylight.
Plastic impellers (in the Hybsun 3UP750 sibling, for example) are the right choice for installations on clean groundwater — efficient, well-priced, well-matched to those conditions. The Hybsun 3US750-60-6C DC solar stainless steel impeller well pump’s AISI 304 stainless steel impeller is the construction grade specifically matched to that kind of abrasive duty. AISI 304 is a corrosion-resistant grade used in food processing, medical equipment, and marine applications — it resists rust from chlorides (common in Cyprus groundwater), pitting from mineral content, and abrasion from sand. Same hydraulic performance as the 3UP750 plastic-impeller version — the choice between them comes down to your well water chemistry. The pump’s entire wet end is stainless: jacket, stage casing, diffuser, impeller, wear ring, strainer, even the screws.
Hybsun backs the Hybsun 3US750-60-6C DC solar stainless steel impeller well pump with a 2-year manufacturer warranty.
