Davey Drainage Single Channel 'Cutter' Impeller Submersible Wastewater Pumps (Max 2150LPM/320kPa)

Designed for high-performance wastewater transfer, the Davey D Series submersible pumps with cutter impellers are built to handle sewage, effluent, and grey water containing soft solids or stringy waste. Featuring an open single-channel impeller with a cutting edge, these pumps effectively break down fibrous materials to reduce the risk of clogging — ideal for applications such as sump emptying, septic disposal, light slurry movement, and industrial wastewater transfer.

Constructed with corrosion-resistant 304 stainless steel and equipped with a double mechanical seal in an oil bath, the cutter range offers enhanced durability and long service life, even in demanding environments. With flows up to 2150LPM and heads to 32m, these pumps are suitable for pressure sewer systems and other high-head installations where solids may be present in the fluid stream.

Note: Cutter impellers are not suitable for sanitary products. For those applications, use the Davey Grinder Impeller models.

FEATURES

• Corrosion resistant 304 stainless steel shaft, motor shell and fasteners allow for long service life and an attractive lasting appearance.
• Open impeller, single channel, centrifugal design with cutting leading edge - Able to pump soft solids in suspension, making it less susceptable to blockage and capable of higher heads/pressure.
• The design of the impeller also is able to cut string like materials, reducing the risk of blockage in the pump or pipework.
• Double mechanical shaft seal in oil bath with hard faced silicon carbide / ceramic seal on pump - Added motor protection, long service life.
• Sand slinger lip seal - Added protection and long service life.

APPLICATIONS

• Sewage water pumping
• Sump emptying
• Septic effluent disposal
• Water transfer
• Pumping of light slurries and factory waste
• Pumping waste water with stringy or long soft solids in suspension.

Suitable Fluids: Semi-screened sewage or 'grey water' of neutral pH containing up to 20% small soft liquids or 1% string like solids. Some wear should be expected while pumping hard solids in suspension.

Note: Cutter pumps are not suitable for sanitary products - use Grinder models.
