DUMAC Column Pumps
We Service What We Sell
At W&P Pumps, we manufacture, supply, and service Australia’s toughest agricultural irrigation and effluent pumping systems from our Kyabram engineering facility. As the home of Australian-made DUMAC vertical column pumps, we build heavy-duty pumps engineered specifically for abrasive farm runoff, dairy sumps, and high-volume irrigation water reuse across the Goulburn Valley, Murray Valley, and Riverina.
Irrigation Agriculture Pumps
Genuine Australian-Made DUMAC Ruffy & Filter-Cut Vertical Column Pumps
Engineered to keep working in harsh agricultural sumps where standard submersible pumps clog or burn out, the DUMAC column pump range keeps the electric motor safely mounted above the pit while a heavy-duty line shaft drives the submerged impeller:
- DUMAC Ruffy Column Pumps (SR50, LRF50, XLRF50, LRF80, XLRF80): Open-impeller vertical column pumps (4.0 kW to 15 kW, column lengths from 1.2m to 3.0m) delivering up to 34 L/sec for dairy yards, tailwater reuse pits, and solids-laden farm water.
- DUMAC Filter-Cut Chopper Column Pumps (SW40, LW40, XLW40, HW40, LWH40, XLWH40, HA50): Fitted with a hardened cutting action to shred stringy fibrous manure, silage, and heavy dairy effluent without blocking sprinklers or travelling irrigators.
- Complete Turnkey Integration: Pair your DUMAC pump with our dairy effluent & green water flood wash systems, HDPE floating pontoons, high-volume mixed flow flood pumps, and Agrinco aluminium flood valves.
