Functional engineering application
The BLX-BSP-2200 Stainless Submersible Deep-Well Borehole Pump is engineered for deep aquifer water extraction across Kenya's rift valley, central highlands, coast, and arid regions. Designed to fit standard 4-inch (100mm) or larger borehole casings, the pump consists of a multi-stage centrifugal hydraulic wet-end coupled to a continuous-duty rewindable oil-filled submersible 3-phase motor. The outer pump sleeve, discharge head, motor bracket, and shaft are precision-fabricated from corrosion-resistant AISI 304 stainless steel. Featuring floating stage impellers molded from wear-resistant Noryl polymer, the pump handles suspended abrasive sand concentrations up to 50 g/m³ without impeller binding. A built-in spring-loaded stainless steel non-return valve protects against hydraulic water hammer during pump cycling.
Heavy-duty 4-inch multistage stainless steel deep-well borehole submersible pump powered by 3.0 kW (4 HP) 415V 3-phase motor, delivering 140m maximum head and 12 m³/h flow capacity.

Common questions on this part
Yes. The 3-phase 415V motor is 100% compatible with solar variable frequency drives (such as the BLX-SPI-3100) for off-grid solar borehole pumping without batteries.
For a 3.0 kW 415V 3-phase pump at 100 meters, 4-core 4.0 mm² flat submersible drop cable is recommended to keep electrical voltage drop under 3%.
The pump wet-end and motor follow the international NEMA 4-inch splined shaft and 4-stud flange standard, allowing the wet-end or motor to be replaced independently with Franklin Electric, Grundfos, or Coverco units if ever required.
Heavy-duty 2" Class D uPVC threaded borehole column pipes or HDPE PN16 poly pipes with stainless steel adaptors are recommended for supporting the pump weight and water column.
STARNEX provides a 12-month manufacturer warranty on borehole pumps and full technical support from our Nairobi headquarters.
