DMT 250-4 1450 RPM Single-Channel Sewage Pump 1400l/min 9.6m Heavy
-
HIGH-CAPACITY INDUSTRIAL EFFICIENCY: Moves a massive water volume up to 1400 L/min (84 m³/h) with a maximum pressure head of 9.6 meters, rapidly clearing sewage pits, civil sumps, and flooded industrial areas.
-
RELIABLE THREE-PHASE POWER: Engineered for 400V three-phase industrial power grids, ensuring consistent performance and optimized energy savings during continuous heavy-duty operations.
-
EXTRA-LARGE 60 MM SOLID PASSAGE: Equipped with a solid cast iron single-channel impeller that allows suspended solids up to 60 mm in diameter to pass through smoothly without clogging.
-
EXTREME 20-METER SUBMERSION DEPTH: Built for extreme underwater conditions with a heavy-duty cataphoresis-painted cast iron body, supporting continuous duty submerged down to 20 meters deep.
-
PRO-GRADE OIL-BARRIER DOUBLE SEAL: Features a double mechanical seal with an oil barrier (silicon carbide on pump side, ceramic-graphite on motor side) and an AISI 304 stainless steel shaft for total motor protection (IPX8 waterproof rating).
Product information
The Pentax DMT 250-4 is a heavy-duty Italian submersible sewage pump specifically engineered for civil, industrial, and agricultural heavy use. Built with a solid cataphoresis-coated cast iron pump body and cast iron single-channel impeller, it provides extreme durability and corrosion resistance for continuous underwater service down to 20 meters.
Unlike standard drainage pumps, the DMT 250-4 utilizes a specialized 4-pole single-channel impeller. This low-speed hydraulic design combines high energy efficiency with an extra-large 60 mm (2.4-inch) free solid passage, allowing raw sewage, grey water, and black water with thick solids to move through without clogging. Driven by a robust 1.8 kW (2.5 HP) three-phase motor running at 1450 RPM, it delivers an enormous flow rate up to 1400 L/min.
Designed for maximum reliability under tough conditions, the pump incorporates an oil-barrier double mechanical seal (silicon carbide / ceramic-graphite), A2 stainless steel bolts, NBR gaskets, a galvanized iron foot support, and an AISI 304 stainless steel shaft. Complete with a 10-meter H07 RN8F power cable, the Pentax DMT 250-4 is the ultimate high-capacity pump for heavy-duty civil and commercial sewage systems.
Note: Suitable for clean water, grey water, and black water with suspended solids up to Ø max 60 mm at liquid temperatures from 0°C to +40°C.
