Pumpmaster STA-112DS Automatic Submersible Non Clog Sewage Pump with Float 

The Pumpmaster STA-112DS Submersible Sewage Cutter & Shredder Pump is a compact, heavy-duty wastewater pump designed for reliable sewage transfer in residential, commercial, and light industrial applications. Built with Pumpmaster’s proven cutter pump technology, the STA-112DS delivers dependable performance where fibrous waste, suspended solids, and raw sewage must be handled efficiently.

This model features a single-vaned, semi-open, non-clog impeller combined with an advanced shredder mechanism that cuts and macerates solids before discharge, helping to prevent blockages in pipework and downstream systems. Its rugged construction and stainless steel motor casing ensure long service life, even in harsh operating environments.

Designed for ease of installation and operation, the STA-112DS offers quiet, smooth running thanks to its hydrodynamically balanced impeller. A double mechanical seal with oil seal protection safeguards the motor against ingress, reducing maintenance requirements and extending pump life. The STA-112DS is an ideal choice for smaller sewage pits, septic systems, and collection sumps where reliability and compact size are essential.
