High-Head Heavy-Duty Waste Management: The Davey Single Channel Sump Pump (D75SA)
Engineered for demanding sewage and stormwater applications, the Davey Single Channel Sump Pump (D75SA) is a robust, high-head submersible pump built to handle tough waste duties. Featuring an efficient single-channel open impeller design and an automated tethered float switch, it effortlessly manages greywater, blackwater, and soft solids without risking blockages
Key Features & Benefits
Single-Channel Open Impeller: Specifically engineered to handle soft solids in suspension while delivering higher head pressure and minimizing the risk of clogging in the pump or pipework.
Automatic Float Switch Operation: Fitted with a pre-set tethered float switch ("A" model) for safe, unattended, automated on/off control.
Corrosion-Resistant Construction: Built with a high-grade 304 stainless steel motor shell, shaft, and fasteners for long-term durability and protection against aggressive wastewater environments.
Double Mechanical Shaft Seal: Operates in an oil bath featuring a hard-faced silicon carbide/ceramic seal on the pump side, supplemented by a sand-slinger lip seal to maximise motor protection.
Built-In Thermal Overload: Automatically protects the motor against overheating and over-current scenarios, ensuring a long operational life.
Slide Rail Compatibility: Fully compatible with Davey slide rail kits (such as the SR50, sold separately) for easy removal, maintenance, and re-installation in deep pits.
Technical Specifications
Motor Output - 0.75 kW (1.0 hp)
Electrical Supply - 220–240V, 50Hz, Single Phase
Full Load Current - 7.5 A
Maximum Flow Rate - Up to 360 Litres per minute (LPM)
Maximum Total Head - High-head performance profile
Impeller Type - Open centrifugal single-channel
Power Cable - 10-metre heavy-duty HO7RN-F oil-resistant lead
Materials of Construction - 304 Stainless Steel (Shaft, Shell, Fasteners)
Versatile Applications
Sewage & Blackwater Disposal: Reliable removal of domestic and commercial sewage waste.
Stormwater & Flood Mitigation: Rapid evacuation of heavy stormwater run-off from below-ground pits.
Septic Effluent Management: Efficient transfer of treated or primary septic waste.
Industrial & Factory Waste: Handles light slurries, washdown liquids, and greywater transfer.
Dependable power for heavy-duty waste management. Keep your property clear of complex blockages with Davey engineering.
