Description

4 Inch Solar Borehole Pump 220V (3 Phase) Submersible Motor

For high performance agricultural, commercial, rural water supplies and off grid water requirements where power supply is unstable or non existent.

For water supply from boreholes, wells, reservoirs and dams or rivers. Domestic use, agricultural, irrigation, civil and industrial applications.

Our 4 Inch Solar Borehole Pump Motors are interchangeable with most 4″ Borehole Pump Wet Ends on the market. These 4 Inch Solar Borehole Pump sets are robust and reliable, giving you the choice of a wide range of pressure and flow rate requirements to suite your specific solar borehole pumping needs.

For surface booster pump use, dual winded 220V/380V 3 phase motors are available on request.

DC~AC PUMP INVERTER

(220to370V DC ~ 220V 3 PHASE AC)

is the next level solution for equipping of new or converting of existing boreholes that is capable of delivering flows of 1000L/h to 22000L/h at total pump pressures of 2 to 30 bar. The inverter works hand in hand with a 4” 220V 3PH motor to accommodate standard NEMA 4” pump couplings for 0.75 to 5.5kW. The reason for the special 3 phase motor voltage is the lowering of the DC input voltage to accommodate smaller PV panel arrays.

If, for example your solution requires a 0.75kW motor, you would need at least 750W X 1.3 = 975W or rounded up, 1000W to accommodate all losses and ensure maximum demand for a 6 hour daily cycle. The input voltage requirement from the solar panel array is 220V to 370V DC (If a 380V 3PH motor had been used, the DC input voltage requirement would be 420 to 710V DC ). A simple array of 4 x 250W/72V PV panels would deliver a perfect 1000W and 288V DC.
