Davey DT75K Stainless Steel 4" High Capacity Sewage Cutter Pump for Septic Disposal with Open Impeller

Scaling down continuous physical maintenance is paramount for massive aquatic infrastructures, and the DT75K 4" Sewage Cutter Pump delivers unprecedented economic endurance. By utilizing an aggressive cutting architecture that obliterates debris directly at the fluid intake, this flagship unit entirely mitigates costly manual pipeline clearing labor.

Commanding this exceptionally demanding fluid management operation is a towering 7.5 kW heavy-duty motor, drawing continuous power from a stable 415v three-phase grid. Engineered for maximum capacity, it evacuates an astonishing maximum flow of approximately 2650 L/Min. It reliably produces a maximum head of approximately 21 meters.

The fundamental structural containment effectively binds the vibration-dampening strength of industrial cast iron directly with the supreme chemical resistance of a 304 stainless steel central shell. This advanced metallurgical strategy optimally diffuses immense operational heat while entirely preventing internal corrosion during relentless submerged deployment.

Acting as an impenetrable final fail-safe barrier, an embedded internal thermal overload mechanism automatically terminates the electrical circuit if temperatures approach hazardous limits. This defense is perfectly complemented by a captive oil bath sealing array utilizing hard-faced silicon carbide to isolate the internal fluid path safely.

Features

• Designed specifically to easily process raw maximum soft solids occupying up to exactly eighty percent of the primary internal discharge throat clearance.
• Operates utilizing a precise 1450 rpm low-velocity four-pole drive configuration to guarantee maximum sheer rotational crushing force upon debris intake.
• Features a massive 90-kilogram physical structural weight to perfectly anchor the pumping system against violent kinetic forces within turbulent tanks.
• Expels massive volumes of critically processed thick slurry directly through an aggressively widened 100mm robust cast iron side discharge port.
• Includes a specialized heavily reinforced 304 stainless steel lifting handle enveloped in durable NBR rubber for highly confident vertical retrieval.
• Manufactured with an exceptionally high-strength hardened cast iron internal diffuser plate to accurately channel internal fluid pressures efficiently.
• Employs premium quality nitrile rubber elastomers across all major housing connection points to ensure absolutely tight environmental fluid containment.
