Davey DT37/SS 316 Stainless Steel Double-Seal Centrifugal Pump for Septic Disposal with Open Impeller

Addressing long-term operating cost scaling in large industrial complexes requires a heavy-duty pumping solution like the Davey DT37/SS which combines massive volume transfer with extreme durability. This powerful three-phase unit is equipped with a high-performance 3.7 kW motor designed for stable hydraulic behavior and consistent circulation in deep pits. By addressing the environmental demands of large-scale water accumulation, the pump ensures structural protection through high-capacity fluid removal of clean or grey water. The system effectively manages septic disposal in heavy-service duty cycles.

Generating massive hydraulic force for industrial tasks, this model achieves a maximum flow rate of approximately 1200 L/Min and reaches a maximum total head of 23 metres. The motor operates on a three-phase 415v supply with a rated run current of 7.5 Amps, ensuring efficient energy use during prolonged discharge cycles. This performance profile is engineered to provide the necessary torque for consistent behavior in deep sub-surface pits and commercial drainage sites. The high volumetric throughput is managed through the 100mm outlet port, ensuring rapid evacuation from large sites.

Hydraulic efficiency is centered on a 316 stainless steel open impeller that facilitates the passage of soft solids in suspension without compromising flow velocity. This centrifugal design is engineered to resist blockages, allowing the pump to manage liquids containing up to ten percent soft solids of 10mm diameter. By maintaining hydraulic balance, the unit reduces internal vibration and wear, which significantly extends the functional life of the rotating assembly in harsh settings. The open impeller configuration ensures that septic water disposal remains uninterrupted even when debris is present.

Structural longevity is provided by a 316 stainless steel motor shell and pump body with Viton elastomers for superior resistance in submerged service. Motor security is maintained by a double mechanical shaft seal in an oil bath featuring premium silicon carbide and ceramic faces to provide an abrasive barrier. For operational security, the unit includes an automatic resetting thermal overload and a sand slinger lip seal to prevent damage from electrical or thermal stress. The assembly is completed with a 10-metre HO7RNF oil-resistant lead and an integrated 316 stainless steel lifting handle.
