DTRT 750 High Head Grinder Water Pump 360lmin 46.2m Flooded Areas
HEAVY-DUTY SEWAGE SHREDDING SYSTEM: Equipped with an industrial-grade treated stainless steel grinder that easily shreds organic solids, textiles, rags, and filamentous fibers in black water to completely eliminate clogging risks.
HIGH-EFFICIENCY HYDRAULIC DISCHARGE: Delivers an impressive water volume up to 360 L/min (21.6 m³/h) with a high pressure head reaching up to 46.2 meters, quickly emptying deep septic tanks and flooded sumps.
OPTIMIZED 3-PHASE POWER OUTPUT: Powered by a 5.5 kW (7.5 HP) 400V oil-bath induction motor designed to maximize hydraulic torque while keeping electrical consumption low, reducing running costs during heavy daily operations.
EXTREME 20-METER SUBMERSION DEPTH: Engineered for continuous heavy duty under high water pressure, supporting safe submersion down to 20 meters deep—four times deeper than standard drainage pumps.
PRO-GRADE CAST IRON CONSTRUCTION: Built with a cataphoresis-painted cast iron body and cast iron open impeller, AISI 304 stainless steel shaft, A2 stainless steel bolts, galvanized iron foot support, and an oil-barrier double mechanical seal (IPX8 waterproof rating).
Product information
The Pentax DTRT 750 is a heavy-duty, industrial-grade Italian 3-phase submersible sewage grinder pump engineered for demanding residential, civil, and agricultural wastewater applications. Constructed with a cataphoresis-coated cast iron body and a cast iron open impeller, it provides extreme durability and rust protection for continuous underwater use down to 20 meters.
Unlike standard drainage or sewage pumps, the DTRT 750 features an integrated treated stainless steel grinder mechanism paired with a powerful 7.5 HP (400V) oil-bath motor. This shredding system easily pulverizes sewage, rags, textiles, and organic fibers in septic tanks and flooded areas into fine slurry, preventing pipe clogs and allowing smooth pumping through standard 2" G discharge outlets.
Engineered for maximum reliability and lower energy bills, the DTRT 750 includes a professional double mechanical seal in an oil chamber (silicon carbide on the pump side, ceramic-graphite on the motor side), A2 stainless steel bolts, and an AISI 304 stainless steel motor shaft. Equipped with a 10-meter H07 RN8F power cable, the Pentax DTRT 750 is the ultimate high-head shredding solution for seamless wastewater management.
Note: Suitable for clean water, grey water, and black water containing sewage and organic fibers at liquid temperatures from 0°C to +40°C.
