The Pentax DTR 150 is a heavy-duty submersible grinder pump engineered for domestic and light-industrial sewage, wastewater, and drainage applications where high head and solids maceration are required. Its integrated grinder allows reliable handling of textile and filamentous fibers and other suspended solids, making it ideal for septic, municipal, and agricultural waste systems as well as challenging basement or remote discharge installations. Key Performance and Specifications The single-phase 230V model delivers 1.1 kW (1.5 HP nominal). It offers a flow range up to approximately 300 L/min and a maximum head of around 18−19 m, depending on the power frequency and installation specifics. The unit is available in free-standing or guide-rail configurations and features a 2" outlet. Its maximum immersion depth is rated up to 20 m. These attributes position the DTR 150 as a compact, high-head sewage pump for long-run discharges. Construction and Durability Rugged Construction: Features a cast iron pump body and impeller with a stainless steel (AISI 304) motor shaft for excellent corrosion resistance. Durable Sealing: Uses a double mechanical seal with an oil barrier and silicon carbide sealing faces, ensuring long life in abrasive and contaminated fluids. Protection: The motor is oil-filled and the unit is IPX8/IP68-rated for complete submersion. It is supplied with a 10 m cable on many configurations. Solids Handling: The grinder mechanism reduces suspended solids to manageable sizes for efficient pumping. (For specific particle size limits, consult the technical datasheet.)
