Small Drainage Pumps

Product catalog summary
Applications: The Davey Submersible Drainage Pumps are suitable for grey water pumping, sump emptying, septic effluent disposal, water transfer, and pumping of light slurries and factory waste.
Design Features: These pumps feature a semi-vortex, open impeller, centrifugal design that allows for the pumping of soft solids in suspension, reducing the risk of blockages. The D15VA and D15VAGMA models include a special recirculation port to agitate soft solids, enhancing their pumping capability.
Construction and Materials: The pumps are constructed with corrosion-resistant 304 stainless steel for the motor shell, shaft, strainer, and fasteners, ensuring a long service life and an attractive appearance. The impeller is made of polycarbonate, and the pump casing is cast iron or glass-filled polycarbonate, depending on the model.
Sealing and Protection: A double mechanical shaft seal in an oil bath with a hard-faced silicon carbide/ceramic seal on the pump side provides added motor protection and longevity. The sand slinger lip seal offers additional protection.
Electrical and Operational Specifications: The pumps operate on a nominal supply voltage of 220-240V, 50Hz single phase. They feature automatic resetting thermal overload protection and are equipped with HO7RNF oil-resistant leads, 10 meters long with a 3-pin power plug.
Operating Limits: The pumps can handle capacities up to 240 liters per minute with heads up to 7.5 meters. They can be submerged up to 12 meters and operate at a maximum temperature of 50ºC. They are suitable for fluids containing up to 10% small soft solids or 1% fine solids.
Installation and Maintenance: It is recommended to use a rope for positioning and retrieving the pump to avoid damaging the power lead. Regular inspection and cleaning are advised to prevent wear from abrasive materials and to ensure the float switch operates correctly.
Hydraulic Performance: The hydraulic performance graph indicates the flow rates and total head capabilities for different models, with specific cut-in and cut-out levels for the D15VAGMA model.

Sump Pumps MATERIALS OF CONSTRUCTION OPERATING LIMITS SUITABLE FLUIDS Clean or “grey water” of neutral pH containing up to 10% small soft solids or 1% fine solids. Some wear should be expected while pumping hard solids in suspension. ELECTRICAL DATA * Nominal supply voltage 220-240V, 50Hz single phase INSTALLATION & PRIMING Use a rope to position and retrieve the pump. Do not lower or retrieve the pump using the power lead as this may damage the cable entry seals, causing water leaks and unsafe operation. Don’t use this product for recirculating or filtering swimming pools, spas, etc. While these...
