Specifications
Technical specifications
- Borehole diameter
- 4-inch units are the common choice in Uganda; 3-inch for narrow holes and 6-inch for high-yield boreholes
- Motor power
- Roughly 0.37–7.5 kW (about 0.5–10 HP) for 4-inch borehole pumps
- Flow rate
- Roughly 20–350 l/min (about 1–21 m³/hr) for 4-inch multistage pumps; 6-inch units go higher
- Maximum head
- Commonly 40–200 m; high-stage 4-inch pumps can lift well beyond 300 m
- Power supply
- 240 V single-phase with a control box up to about 3 HP; 415 V three-phase above that
- Protection / cooling
- IP68 fully submersible, cooled by the water flowing past the motor — it must stay submerged to avoid burnout
- Maximum immersion depth
- Typically 100–200 m below water level depending on motor type
- Sand tolerance
- Roughly 50–200 g/m³; sandy boreholes need a flow sleeve or better screening to protect the pump
- Materials
- Stainless steel sleeve, delivery port and shaft, with engineered-polymer impellers and diffusers

Applications
What it is used for
A submersible pump supplied by JamaliTech in Kampala is a multistage borehole pump whose motor sits underwater at the bottom of the well and pushes water up the rising main — it does not suck from the surface, which is why it works where a surface pump cannot. In Uganda these are the standard machine for boreholes serving homes, schools, clinics, farms and irrigation schemes, most commonly 4-inch units of about 0.5–10 HP. Correct selection depends on three numbers from your borehole: the depth to water, the height to your tank, and the yield the hole can sustain.
- Lifting water from boreholes for village, school and church water points
- Filling elevated or rooftop tanks for hotels, hostels and rental units
- Feeding drip and sprinkler irrigation on coffee, banana and vegetable plots
- Supplying drinking troughs for dairy herds and poultry units
- Filling water bowsers and site tanks on construction projects
- Solar-powered borehole schemes in off-grid districts
Questions buyers ask
How deep can this pump go in my borehole?
Most 4-inch submersible pumps are rated for installation up to about 100–200 m below the water level, and their pumping head — the total height they can push water — is separate from that. The figure that matters for selection is total head: depth to the water plus the height up to your tank plus friction in the pipe. Bring the driller's borehole log to JamaliTech in Industrial Area and they will match a pump to it.
Can I run it on solar instead of UMEME?
Yes — solar borehole pumping is widely used in Uganda, either with a dedicated DC solar pump or with a standard AC pump driven through a solar pump inverter and a matched panel array. The sizing is different from a grid installation because output follows the sun, so you generally pump into a storage tank during daylight rather than pressurising on demand. Discuss the daily water demand with the team so the array and tank are sized together.
Will it work on single-phase power at my home?
Up to roughly 3 HP, yes — single-phase 240 V models with a control box are normal for domestic and small farm boreholes. Above that, three-phase 415 V is the usual requirement, which means either a three-phase connection or a suitably sized generator. Fitting a dry-run protector is strongly advised either way, because a submersible pump that runs with no water burns out its motor quickly.
