Davey DT15 Cast Iron Double Seal Submersible Drainage Pump for Factory Waste Water with Open Impeller

Clearing high volumes of water from industrial sumps requires the high-torque performance found in the Davey DT15 three-phase pump. This 1.5 kW / 415v unit provides a maximum head of approximately 17 metres and a flow rate reaching approximately 640 L/Min for large-scale water transfer. It is engineered to handle the operational load challenges of factory drainage and commercial site ditches where consistent dewatering is critical for facility safety. The robust mechanical assembly ensures that sub-surface structures remain dry even during periods of heavy fluid influx.

Hydraulic capacity is driven by the balanced 415v electrical supply, maintaining a 3 Amps run current during peak discharge cycles. This three-phase configuration ensures rapid evacuation of water from large pits through the 80mm outlet port, providing a reliable solution for commercial site maintenance. The motor operates at a synchronous speed of 2850rpm, maintaining steady hydraulic pressure and circulation stability in deep industrial pits. By addressing the demands of pumping neutral pH grey water, the DT15 offers a heavy-duty dewatering alternative for high-volume applications.

The internal hydraulic system utilizes a cast iron open impeller designed for superior solids handling and circulation stability. This centrifugal arrangement is specifically configured to manage fluids containing suspended soft solids, making it less susceptible to blockages compared to closed designs. By facilitating clear fluid velocity paths, the impeller design reduces internal wear and maintains high volumetric efficiency even when water quality contains fine impurities. This configuration is essential for industrial dewatering where environmental debris or factory waste may be present in the liquid stream.

Architectural casting design features a rugged cast iron pump body and motor top for maximum structural durability during continuous service. Longevity is anchored by a double mechanical shaft seal housed in an oil bath, featuring a hard-faced silicon carbide and ceramic seal on the pump side for maximum wear resistance. The motor is further protected by a sand slinger lip seal and an internal automatic resetting thermal overload to prevent burnout from electrical stress. The assembly is completed with a 10-metre HO7RNF oil-resistant lead and 304 stainless steel fasteners to ensure lasting integrity in submerged conditions.
