Engineered to optimize fluid velocity paths, the DIWA11T grey water pump manages high-capacity transfer. Representing submersible pumps for clean and slightly dirty water manufactured in AISI 304 stainless steel, this architecture supports the extraction of fluids from cellars. The system continuously assists the pumping of domestic wastewater.
Fluid is propelled by an open impeller connected to a three-phase 415v configuration without a float switch. The watertight motor utilizes a 1.1 kW output capacity, drawing 2.68 Amps. The assembly delivers a max flow of approximately 375 L/Min and achieves a max head of 13.4 m. The dry motor is cooled by the pumped liquid up to 50°C.
Wear along the primary shaft is controlled by the DRIVELUB SEAL SYSTEM, a seal layout encompassing an internal oil chamber. This merges a V-ring with a silicon carbide seal to supply a barrier against infiltration. The diffuser plate is coated with polyurethane for resistance to abrasion. Intake is managed via a 32 mm base inlet.
With a net weight of 15 kg, the unit provides stable positioning. Pressurized fluid exits through a 32 mm outlet. The device is equipped with a 10-meter H07RN-F power cord, meeting IPX8 standards for absolute submersion. This layout passes suspended solids up to 8 mm while maintaining Class F electrical insulation limits.
Features
- Manufactured utilizing EN 10088-1-X5CrNi18-10 stainless steel for the impeller and motor casing.
