45kW 160 m³/h 60 m Head Deep Well Submersible Pump and Borehole Submersible Pump for Farmland Irrigation

The 250QJ160-60/4 is a deep well submersible water pump built for a steady mid-head duty point: a 45kW motor driving a four-stage hydraulic section with a nominal 160 m³/h at 60 m head. It is the type of borehole pump that runs for long hours during the irrigation season, so the design priorities are simple ones — a duty point that matches the well, hydraulic components that suit the water, and a power supply that is confirmed before the order is placed.

These are the model's nominal specifications and catalogue ranges. We use your pumping water level, delivery elevation, pipeline losses and required outlet pressure to determine the system requirement, then check it against the pump performance curve. The maximum catalogue flow and maximum catalogue head should not be treated as a simultaneous operating point.

Reading a QJ series deep well submersible pump model is straightforward once the layout is known: 250QJ160-60/4 means a pump intended for a 250mm borehole, QJ designating the deep well submersible pump family, 160 m³/h nominal flow, 60 m nominal head and 4 stages. The borehole figure is a model designation, not an installation guarantee — the pump diameter, riser pipe and cable have to be checked against your casing size and the installation drawing before shipment.

• Farmland and orchard irrigation — where the required flow and total head match the selected pump curve, feeding drip, sprinkler or surface irrigation lines from a borehole.
• Rural and municipal water supply — lifting from a deep well into a reservoir or a distribution network.
• Livestock and poultry water supply — filling storage tanks on farms with a matching duty point.
• Industrial and construction water transfer — moving groundwater to a process tank, settling pond or site storage.

Because the head is moderate, this 160 m³/h deep well submersible pump is normally used where the pumping water level is not extremely deep and the delivery distance is moderate. For a higher required head, we compare suitable hydraulic configurations and confirm the motor power from the selected performance curve.

Six figures decide the selection. The more of them you can supply, the faster the model and performance curve can be checked against your project.

• 1. Required flow rate (m³/h) — what the irrigation system, reservoir or network needs at peak demand, not the maximum the pump can pass.
• 2. Total head (m) — pumping water level plus delivery elevation, pipe friction losses, fittings and the pressure required at the outlet. Static water level alone is never enough.
• 3. Borehole data — casing diameter, total depth, screened section and the safe yield of the well, so the pump is not asked to draw more than the aquifer can give.
• 4. Power supply — voltage, frequency and phase. A 50Hz and a 60Hz version of the same pump use different curves, so the curve for your supply must be the one used for the selection.
• 5. Water conditions — sand content, temperature, and whether the water is mildly aggressive or intended for drinking. These decide the material grade of the hydraulic components and the sealing arrangement.
• 6. Operating pattern — continuous or intermittent duty, and whether a control panel, soft starter or VFD will be used. This affects the motor protection scope and the starting method.

• Hydraulic components: cast stainless steel. The material grade and the exact component scope are confirmed according to the water quality and the project requirements rather than assumed from the model code.
• Power supply: configured per order. Voltage, frequency and phase are stated in the quotation, together with the matching performance curve.
• Control equipment: please specify whether a control panel, soft starter or VFD is required. The selected equipment and its protection functions will be listed in the quotation.
• Cable and riser pipe: lengths are quoted against your installation depth, and the pump is supplied to suit the agreed configuration.

Confirm the pump setting depth, minimum submergence and motor cooling requirements against the well layout and the installation manual. Secure the cable with suitable supports and protect it from rubbing or crushing. Check the valve arrangement and any surge-control requirements for the delivery pipeline. Never lift or suspend the pump by its electrical cable.

Record running current, flow and discharge pressure during commissioning. If these readings change, check the water level, power supply, valves, pipework and pump condition before deciding on corrective action. Increased sand in the discharge water should also be investigated.

Avoid repeated starts within a short period, and use the control equipment to limit start frequency where the supply or the motor requires it. Keep spare parts identified with the order so that replacements match the same configuration.

We test our pumps before shipment and pack them after they pass the required checks. Any specific test records or inspection requirements should be agreed before ordering. Packing method is stated in the quotation.

• A pump manufacturer and exporter established in 1986, with 301–500 employees and 90–100% of output exported.
• OEM and ODM production, so nameplate, voltage, frequency and packing can be set for your market.
• Selection support on borehole duty points: send your water level, flow, head and power supply and our engineers will check the model and curve against them.
• ISO 9001:2015 manufacturer; product certification requirements can be discussed per project.
