Davey Wastewater and Drainage Pumps in Perth
Davey offers an extensive range of wastewater, sewage, and drainage pumps tailored to handle everything from clean rainwater runoff to heavy raw sewage. These systems are readily supplied and serviced across Western Australia by local specialist dealers like
Shenton Pumps. The primary Davey wastewater pump models used for residential, commercial, and agricultural applications in Perth are categorised by their specific waste-handling capabilities below:
Sewage and Raw Waste Management
Davey D75SA Sewage Pump
A heavy-duty submersible sewage pump commonly deployed for domestic and light commercial wastewater applications. It is designed to reliably handle solids in suspension.
Davey Submersible Grinder Pumps
Frequently installed in deep sewer pits or locations requiring wastewater to be pumped over long distances or high heads. They feature an integrated cutting mechanism ideal for breaking down raw sewage and preventing pipeline blockages.
Davey Submersible Cutter and Shredder Pumps
Tailored specifically for commercial or agricultural waste management, these units effectively cut down fibrous materials and thicker organic waste before transfer.
Davey Mukmova Effluent Pumps
Highly reliable, surface-mounted effluent pumps engineered for the effective movement of thick farm waste, dairy effluent, or water containing high concentrations of solids.
Sump, Greywater, and Vortex Drainage
Davey DCS40M Greywater Pump
A specialized submersible pump frequently chosen by Perth households for greywater diversion and recycling systems (such as laundry and shower outflow).
Davey Vortex Sump Pumps
These use an open vortex impeller design making them less susceptible to blockages. They are the "jack-of-all-trades" choice for greywater pits or water containing loose, soft solids.
Davey Double-Cased Stainless Steel Sump Pumps
Built with highly durable, corrosion-resistant housings. These are perfectly suited for shallow pit drainage, basement sumps, or continuous drainage cycles.
