Davey D150 Cast Iron Manual Submersible Pump for Large Dewatering with Open Impeller

Hydraulic behavior in the Davey D150 is defined by high-velocity fluid paths through an 80mm discharge port, optimized for large-scale dewatering applications. This model features a 1.5 kW motor delivering up to approximately 640 L/Min, providing the necessary circulation stability for deep pits and industrial ditches. The internal flow configuration is engineered to handle clean or grey water with suspended soft solids, ensuring consistent volumetric efficiency during high-demand transfer cycles. Every aspect of the hydraulic design focuses on maintaining steady pressure and rapid water removal in commercial settings.

Equipped with a powerful single-phase motor, the unit operates on a standard 240v supply with a rated run current of 13 Amps. It achieves a maximum total head of 17 metres, satisfying the requirements for high-elevation discharge from industrial sumps and construction sites. The motor system is protected by a 10-metre HO7RNF oil-resistant power lead, ensuring safe electrical termination in contaminated water environments. This performance profile is specifically engineered to provide the high starting torque necessary for moving substantial volumes of water quickly during flood events.

The hydraulic system utilizes a cast iron open impeller configuration designed to handle soft solids in suspension without risking internal blockages. This centrifugal arrangement maintains high flow velocity through the pump casing, which prevents the accumulation of fine grit that could compromise the mechanical seals. By utilizing a robust cast iron impeller, the unit reduces internal vibration and mechanical wear, significantly extending the service life of the rotating assembly in harsh industrial environments. The design is optimized for liquids containing up to ten percent small soft solids.

Structural integrity is maintained by a heavy-duty cast iron pump body and motor top paired with a corrosive-resistant 304 stainless steel motor shell. Longevity is anchored by a double mechanical shaft seal in an oil bath featuring premium silicon carbide and ceramic materials for the primary pump-side seal. 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 architectural casting includes high-grade 304 stainless steel fasteners and a lifting handle for reliable service in deep sumps.
