Davey D75KA Stainless Steel Automatic Submersible Sewage Cutter Pump for Septic Disposal with Open Impeller

Relying on a fortified external casting architecture, the D75KA Sewage Cutter Pump establishes dominance over harsh subterranean environments. The primary volute utilizes heavy cast iron to ensure dimensional stability while resisting abrasive forces in septic tanks. This armor prevents degradation while managing aggressive fluid tasks.

Transforming energy into hydraulic force is handled by a 0.75 kW electric motor running on a standard 240v circuit. This drive system reaches a maximum flow output of approximately 350 L/Min with a maximum vertical head rating of approximately 15 meters. Heavy materials are safely expelled through a rigidly cast 50mm discharge outlet.

Unattended operation remains consistent thanks to the integrated automatic float switch, dictating activation cycles based entirely on liquid elevation. An included ten-meter harmonized electrical lead guarantees simplified connectivity to distant power sources, ensuring reliable setup even when managing complex waste distribution networks.

To preserve the infrastructure against moisture, a double mechanical seal functions submerged within a captive oil bath. This defense utilizes hardened ceramic and silicon carbide facing for unyielding isolation. Embedded thermal overload safeguards proactively terminate the current loop if temperatures exceed safe margins during operation.

Features

• Integrates an ultra-hard tungsten carbide cutting tip on the impeller leading edge to efficiently shred stringy and fibrous materials.
• Employs a functional sand slinger lip seal configuration that provides secondary specialized defense against abrasive solid particle wear.
• Operates securely with a maximum submergence depth rating of up to 20 meters below the liquid surface for extreme underground applications.
• Designed to handle heavy maximum soft solids measuring up to eighty percent of the designated internal discharge port clearance diameter.
• Features a precisely balanced 304 stainless steel lifting handle wrapped in a robust NBR coating material for confident vertical extraction.
• Utilizes premium high-grade Class F motor insulation parameters to assure long-lasting electrical integrity across demanding wet deployments.
• Includes a functional cast iron mounting base specifically designed to establish a firm physical positioning during permanent installation.
