Product Overview
Engineered to optimize fluid velocity paths and hydraulic stability, the DIWA11 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 assists the continuous pumping of domestic wastewater.
Fluid is propelled by an open impeller connected to a single-phase 240v configuration. The watertight motor utilizes a 1.1 kW output capacity, drawing 6.83 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, permitting operation up to 50°C.
Wear along the primary shaft is controlled by the DRIVELUB SEAL SYSTEM, a seal layout encompassing an 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 inlet and fluid exits through a 32 mm outlet.
With a net weight of 17 kg, the unit provides stable positioning. A pre-assembled float switch governs automatic operation, activating at a minimum liquid level of 25 mm. The device is equipped with a 10-meter H07RN-F power cord, matching IPX8 standards for absolute submersion. This layout passes suspended solids up to 8 mm.
Features
- Manufactured utilizing EN 10088-1-X5CrNi18-10 stainless steel for the impeller and motor casing.
- Features an internal capacitor integrated directly into the electrical starting mechanism.
- Equipped with a Class F insulation framework designed to withstand internal temperatures up to 155°C.
- Includes specialized thermal overload protection built to interrupt power during critical heat events.
- Functions reliably under a maximum immersion depth limit of 7 meters inside collection sumps.
- Constructed with standard NBR elastomers for consistent sealing flexibility across the shaft line.
