Pumpmaster SSA-0512N Stainless Steel Automatic Submersible Sewage Pump for Commercial Septic with Semi-Open Impeller

Reliable management of domestic wastewater and soft sewage is highly efficient with the Pumpmaster SSA-0512N submersible sewage cutter pump. Specially engineered for light residential septic networks, household collection pits, and laundry basement drainages, this automatic utility handles raw domestic wastewater containing fibrous debris. The integrated mechanical float switch provides automated, hands-free level control and start-stop operation, preventing basement flooding and septic overflow without manual monitoring.

Pumping performance is determined by a single-phase, 240V electric motor drawing 0.40 kW of continuous operating power. Under peak conditions, the robust hydraulic configuration delivers a maximum flow rate of 200 L/Min and reaches a maximum vertical discharge head of 10 m, corresponding to an operating pressure of 100 kPa. This balance of flow and lift allows the compact unit to easily clear household waste pits and lift residential wastewater up to the mains sewerage gravity lines.

Hydraulic design is centered around an advanced single-vaned semi-open non-clog impeller working alongside an integrated macerating shredder mechanism. This hardened cutting configuration actively shreds stringy solids and toilet paper down to fine slurry particles before the fluid exits through the discharge manifold, thereby preventing downstream pipeline blockages. The hydrodynamically balanced impeller ensures minimal vibration and prevents structural cavitation during high-flow transfer cycles.

Construction details include a high-strength stainless steel motor casing that maximizes corrosion resistance and ensures optimal thermal heat dissipation during prolonged immersion. The inner seal design features a highly durable mechanical seal coupled with a protective auxiliary oil seal, shielding the motor chamber against sewage liquid ingress. Built-in automatic thermal overload protection safeguards the single-phase winding against electric surges and dry-running damage, maximizing pump service life.
