NEW DAVEY 4″ BOREHOLE PUMPS

A bore can help you unlock water sources beneath the surface, so you don’t have to rely on surface streams or rainwater both of which can be unpredictable in Australia.
But a bore is only as reliable as the pump you use, which is why the new range of Davey borehole pumps is designed with dependability in mind.
Davey’s new range of 4″ borehole pumps and motors are corrosion and abrasion resistant and designed for domestic water supply, turf watering, irrigation, stock watering, dewatering or fountains.
These proven and reliable products are ready for the harshest conditions, ensuring optimal performance in all situations including the sandiest bores.
The new range includes an impressive sand handling capability of up to 300g/m3 – which is double the capacity of the current Davey range.
With an extensive range of 44 pumps offering flow rates from 2m3 to 12m3 per hour, there’s a Davey 4″ bore pump to suit every application.
EFFICIENT. ROBUST. CAPABLE.
