Davey DT15/SS 316 Stainless Steel Three-Phase Drainage Pump for Factory Waste with Open Impeller

Structural housing casting design in the Davey DT15/SS utilizes a complete 316 stainless steel construction to provide maximum durability during continuous industrial service. This three-phase model is specifically engineered for the pumping of neutral, non-aggressive factory waste water and septic disposal in high-demand commercial environments. By incorporating 316 stainless steel for the motor shell, handle, and fasteners, the assembly withstands the rigors of prolonged immersion in grey water. The use of premium materials ensures a lasting professional appearance while protecting internal electrical components.

Hydraulic capacity is driven by a high-performance 1.5 kW three-phase motor operating on a 415v supply, providing significant torque for industrial dewatering. The unit generates a maximum flow of approximately 640 L/Min and achieves a maximum total head of 17 metres, making it suitable for high-elevation discharge. With a rated run current of 3 Amps, the motor is configured for energy-efficient performance while maintaining the hydraulic stability required for continuous service. This performance profile ensures rapid evacuation of water from large factory sumps through the 80mm outlet port.

The internal hydraulic system utilizes a 316 stainless steel open impeller designed for superior solids handling and circulation stability in deep industrial pits. This centrifugal arrangement is specifically configured to manage fluids containing suspended soft solids up to 10mm in diameter, making it less susceptible to blockages. By facilitating clear fluid velocity paths, the impeller design reduces internal wear and maintains high volumetric efficiency even in harsh conditions. This configuration is essential for industrial drainage where environmental debris or factory waste may be present.

Mechanical security is reinforced by a double mechanical shaft seal in an oil bath, utilizing premium silicon carbide and ceramic materials for the primary seal faces. For operational security, the unit includes an automatic resetting thermal overload and a sand slinger lip seal to prevent internal failure from electrical or thermal stress. The assembly includes a 10-metre HO7RNF oil-resistant power lead with bare wire ends for professional industrial termination in three-phase control panels. Viton elastomers are used throughout the unit to provide enhanced chemical resistance in non-aggressive waste water.
