CHALLENGE
Water availability changes.
SOLUTION
Match the abstraction rate to the tested well yield. Allow for pumping-level variation and suitable low-water protection.
THE RESULT
DEEP-WELL WATER SUPPLY SOLUTIONS
Deep-Well Water Supply from Source to Outlet
Plan deep well water supply pumps using well diameter, pumping water level, water quality and the required flow and head. Review the submersible pump and motor, rising main, cable, lifting access and installation conditions together.

CHALLENGE
The pump has to fit and operate below ground.
SOLUTION
Coordinate borehole clearance, setting, motor cooling, rising main and cable as one installation.
THE RESULT
Installation fit and operating conditions considered together.
CHALLENGE
The water still has to reach the user.
SOLUTION
Size the delivery duty from the pumping level to the outlet, including elevation, pipe losses and required pressure.
THE RESULT
Selection based on the complete delivery route.
One connected solution.
Source-aware abstraction
Coordinated installation
Delivery-based selection
THE EQUIPMENT BELOW GROUND
ASJ: the pump and motor go into the well.
The ASJ deep-well assembly brings a submersible pump and directly coupled motor together. Review the assembly as part of the complete borehole installation.
PUMP
Moves water into the rising main.
Select the hydraulic duty from the pumping water level to the delivery point, including pipe losses and required outlet pressure.
MOTOR
Operates below the water level.
Check the motor supply, cooling and submergence requirements against the actual well and selected assembly.
INSTALLATION
Brings the assembly and well together.
Confirm clear borehole diameter, setting constraints, cable route, rising main and lifting access before finalising the arrangement.
AFTER THE WELLHEAD
How will the water reach its users?
The well establishes the available water. The delivery arrangement establishes what the pump must supply.
ROUTE A
From the well to the delivery network.
For direct supply, include the elevation, pipe losses and required outlet pressure in the well-pump duty. Coordinate operation with changes in use and the tested source capacity.
ROUTE B
From the well to storage, then to users.
Where storage is part of the project, review well filling and downstream delivery as separate duties. A booster stage may be considered if the downstream network needs additional pressure.
FROM SITE RECORD TO EQUIPMENT
Bring two records into the same selection.
A well record explains the source and installation. A delivery record explains the water service you need.
01 / WELL & INSTALLATION
Know what is below ground.
Well-test flow and pumping water level Static level, test date and reference datum Clear diameter, casing and setting limits Water analysis and known sand content Power supply, cable route and lifting access
02 / DELIVERY & OPERATION
Know what must happen above ground.
Required flow and operating hours Delivery elevation and outlet pressure Rising main and delivery-pipe route Tank levels or direct-supply demand Start, stop and low-water protection needs
Before choosing a well pump
What does the ASJ product range cover?
ASJ is the BBP deep-well submersible pump family for groundwater supply. Review the complete pump-and-motor assembly, liquid limits, installation diameter and selected model curve against your well and delivery duty.
Will I also need a surface booster pump?
That depends on the delivery arrangement. A well pump may supply the destination directly, or fill storage from which a separate pump serves the network. Assess the downstream pressure requirement before deciding whether a booster stage is needed.
Is total well depth the same as pump head?
No. Delivery head follows the route from the pumping water level to the outlet, including elevation, required outlet pressure and pipe losses. Total well depth also affects installation planning, but does not by itself establish the pump duty.
What if the water level changes during pumping?
Base the review on pumping-test information and known level variation. Match abstraction to the available source, and establish suitable installation and low-water protection requirements for the site.
