4-Inch Solar Submersible Pump, Stainless Impeller

4-inch solar submersible pump with stainless steel impeller, full length view

Overview

The DSC series is the general-purpose 4-inch solar pump: a stainless steel impeller stack inside a 4-inch stainless body, driven by a brushless DC motor, fed by PV panels through a controller. It fits a standard 4-inch borehole, which is the diameter most farm wells are drilled at. The A/D models will also accept mains or generator input and switch between AC and DC on their own — useful where the grid is unreliable rather than absent.

Key Features

Fits a standard 4-inch well — 4-inch outside diameter, so it drops into the borehole you already have.

Stainless steel impeller — Impeller and pump body in stainless steel, for water with light sand or iron rather than clear water only.

Head to 360 m — The deep-well versions reach 360 m of head, which covers boreholes that shallow pumps cannot lift from.

AC/DC automatic switching — Models marked A/D run from PV, mains or a generator and change over automatically.

MPPT controller included — Controller tracks the panel's maximum power point and protects against dry run and over-voltage.

Model code reads: 4 = 4″ well, DSC = impeller type, first number = max flow (m³/h), second = max head (m), third = optimum DC voltage, last = motor power (W). A/D = AC/DC automatic switching. Specifications may be updated by the plant — confirm current values with us before ordering.

Applications

Borehole and deep-well water supply; drip and sprinkler irrigation; livestock watering; village and household supply; tank filling from a well. The high-head versions suit deep static water levels; the high-flow versions suit large irrigation blocks.

Frequently Asked Questions

How do I know which model fits my borehole?

Three numbers decide it: the well diameter (this series is for 4-inch), the total head you must lift (static water level + delivery height + pipe friction + 10–20% margin), and the flow you need per day. Send us those three and we pick the model rather than guessing.

What panel size does it need?

As a rule of thumb the array should be at least 1.3 times the motor rating, adjusted for your local irradiation. A 2,200 W pump therefore needs roughly 3 kWp. We confirm the exact configuration with the plant before quoting.

Can it run from a generator instead of solar?

The A/D models can, and switch automatically between AC and DC. The DC-only models cannot — they need PV. Tell us which you have before ordering, because the controller differs.
