Designing Packaged Pressure Booster Systems for Commercial High-Rises

The plant room still smells of concrete dust, the rising main is already in the shaft, and fixtures need pressure by Friday. A commercial high-rise booster is not one pump on a brake tank; it is [...]

The rising main jumps in the clamps before any valve is touched, and the check has already taken the slam. A water hammer in a bore rising main is a pressure wave, not a noise complaint, and the [...]

Oil in the sample jar turns milky within hours of start-up when the mechanical seal has let aquifer water into the motor. That interface is the only barrier between the hole and the oil bath, and [...]

The annulus goes still the moment casing ID exceeds the motor can and the intake sits above the stator. Warm borehole water sits against the windings instead of sweeping heat off the shell, and a [...]

A bore pump can run for long periods and still be a poor candidate for a variable speed drive. The important question is not whether a drive can slow the motor. It is whether the system needs [...]

Calling groundwater “saline” is a useful warning, but it is not a material specification. Two bores can both be described that way while presenting different chloride levels, pH, temperature, [...]

Sand can be easy to see in a sample and difficult to interpret. It may settle in a container, make water look cloudy or appear after a change in pumping conditions. That does not mean the bore [...]

A bore pump can be doing its work out of sight for long periods, which makes maintenance easy to postpone and hard to schedule well. A sudden change in irrigation coverage, pressure or water [...]

Selecting a bore pump starts with a distinction that is easy to miss: a bore is the water source, while the pump is the machine that must move water through a particular system. They are [...]

A newly installed pump set can look complete while important conditions remain unchecked. A drawing may have changed during installation, pipework may be carrying stress into the pump, or a [...]
