The stainless steel deep well submersible pump has an input power of 1100W, converted to 750W of mechanical output power at the pump shaft, a power split that reflects real-world electrical draw relative to hydraulic work delivered. Both figures are important to know. For electrical circuit sizing, the installation needs to be wired for 1100W input draw at 230V/50 Hz, not the 750W output figure. In permanent installations, the supply circuit is undersized based solely on output power, resulting in nuisance tripping and conductor overheating.
The 750W input of the copper-wire motor is applied as torque to the impeller stack during continuous pumping cycles. Copper windings prevent overheating under continuous load and ensure electrical efficiency across the motor’s service life. Built-in overheat protection automatically stops the motor if the motor temperature exceeds safe limits, an essential safeguard for a pump installed at depth where manual intervention during an overheating event is not possible.
The control box is built into the pump body rather than being a separate external unit that must be mounted, wired, and weatherproofed at the surface. The space-saving integration eliminates an extra installation step, eliminates external control wiring runs from a separate box to the pump, and reduces the number of connection points where moisture ingress or mechanical damage can lead to system failure. The separate control box is no longer needed, greatly simplifying installations in confined wellhead housings or remote field locations with limited above-ground infrastructure.
Built-in control means the pump ships as a complete, self-contained unit, ready to be lowered into the well with no pre-installation component assembly required. Operators familiar with submersible pump installations that require the control box to be mounted and wired separately before commissioning will find the time savings this integrated design provides invaluable. Single-unit construction also makes replacement easy.
At a maximum flow rate of 100 L/min, the stainless steel pump moves more than three times the volume of the 35 L/min unit in the VEVOR deep well range, making it the right choice for applications where flow rate, rather than head depth, is the primary sizing criterion. A lower-capacity pump is inadequate for applications that require continuous high flow rates, such as agricultural irrigation, livestock watering systems, or residential water supplies with multiple simultaneous draw points. The 100 L/min rating is sufficient to support these more demanding applications without requiring multiple pumps in parallel.
The maximum head is 75 m (246 ft), which provides sufficient lift capacity for most residential and light agricultural deep-well installations. As with all performance curves of centrifugal pumps, the actual flow rate decreases with increasing working head; the flow approaches zero at the maximum head. Before installation, operators should determine their specific working head and required flow rate and verify that this stainless steel deep well submersible pump’s performance curve can accommodate both simultaneously.
This pump has IP68 waterproof certification, which means it is sealed for continuous submersion at depth, with all electrical entry points, housing joints, and cable terminations tested for water ingress under pressure. The IEC 60529 standard defines certification and requires testing and verification; it is not a self-declared spec. For a pump that will be operating permanently submerged in groundwater, canal water, or a reservoir, a high waterproofing standard for long-term reliable operation without insulation breakdown or motor winding failure due to moisture penetration is IP68.
The stainless steel body and filtration mesh resist corrosion mechanisms that destroy pumps in mineral-rich groundwater environments over time. Groundwater chemistry varies by location. Stainless steel construction gives broad resistance to these different conditions without the need for protective coatings that can deteriorate and flake off into the water supply. The stainless steel deep well submersible pump weighs 33.63 lbs (15.25 kg), making it manageable for two-person installation and removal from the well casing.
The stainless steel filtration mesh screens debris and particulate matter from entering the impeller housing during pumping and protects internal components from abrasive wear caused by sediment on impeller surfaces and wear rings. Plastic mesh deteriorates in the chemical environment of groundwater, allowing larger particles to pass through as the material weakens. Stainless steel mesh is corrosion-resistant and maintains the geometry of the filter apertures over time.
If new wells are drilled and developed with high sediment levels, an additional pre-filtration can be provided by adding a layer of gauze at the inlet until sediment levels subside. The overheat protection is directly coordinated with the filtration system. A blocked inlet, which reduces flow through the motor cooling path, is one condition that can cause the motor to overheat. Diminished water flow through the motor housing reduces heat dissipation and raises the winding temperature to the protection threshold.
The G1.25 at the discharge outlet is a British Standard Pipe (BSP) thread, a very popular connection format for water supply plumbing systems in Europe and other parts of the world that commonly use 230V / 50Hz electrical infrastructure. This thread standard will be compatible with the standard BSP fittings used in agricultural irrigation pipework, residential water supply risers, and industrial water distribution systems within these markets.
For NPT-threaded areas, operators will require a BSP-to-NPT adapter at the discharge connection to connect to local pipework. The pump body is 4.02 in / 102.4 mm in cross-section and 36.61 in / 930 mm in overall length, which requires a well casing having an internal diameter of at least 0.39 in / 10 mm larger than the outside diameter of the pump body to provide adequate clearance for installation and retrieval.
