Robday supplies and supports Balz vertical spindle pumps for sites where pumping conditions are tough and downtime is costly. These pumps are built for sump and pit installations where the liquid is often dirty, abrasive, or chemically aggressive, and where standard water pumps do not last.

Balz states they manufacture the pump range in-house and focus on dewatering and industrial pumping solutions, which supports consistent build quality and practical support for harsh site conditions.

Vertical spindle pumps are used for sump and pit pumping where conditions are harsh and the liquid is not clean. They are commonly specified to move slurry, sludge, dirty water, abrasive material, and corrosive liquids from plant sumps, process pits, dams, and wastewater collection points, especially where fluid levels change and a vertical installation is more practical.

In mining, wastewater, and chemical processing, these pumps are chosen where reliability and wear resistance matter. Typical uses include keeping sumps clear to prevent flooding, returning spillage to process circuits, and handling abrasive or corrosive fluids that cause standard water pumps to fail early.
