Reliable Power. Repairable Design. Built to Last.
DAB’s 4” water-filled submersible motors are the trusted choice for bore pump systems across Australia. Designed in Italy for long-lasting performance, these motors offer consistent, efficient power delivery for demanding groundwater applications.
Constructed with AISI 304 stainless steel and featuring a water-glycol lubrication system, these motors are built to operate in corrosive environments while handling high axial loads with ease. The internal stator is resin-filled or rewindable (depending on model), delivering maximum durability and repairability—making them ideal for long-term service strategies.
Whether paired with DAB wet ends or other compatible 4” NEMA pump bodies, these motors are known for their efficiency, serviceability, and rugged reliability.
Key Features
NEMA Standard Design
Universal 4” NEMA flange fits a wide range of pump ends for flexible use across systems.
Water-Filled with Glycol Mix
Internal cooling and lubrication via a water-glycol solution provides superior thermal stability and smooth operation.
Repairable Construction
Rewindable or resin-filled stator options, depending on model, allow for on-site servicing—reducing downtime and long-term costs.
Robust Axial Load Capacity
Kingsbury-type thrust bearings provide high load tolerance for deep installations.
Stainless Steel Build
AISI 304 stainless steel components ensure resistance to corrosion and long life in bore environments.
