The DIWA5 model handles domestic wastewater, integrating submersible pumps for clean and slightly dirty water manufactured in AISI 304 stainless steel. This grey water pump manages extraction demands associated with emptying tanks and processing output from washing machines. The system supports draining of cellars and basements.
Powered by a single-phase 240v setup, the motor generates 0.55 kW output drawing 3.92 Amps. The assembly achieves a max flow of approximately 250 L/Min and max head of 8.6 m. Thermal overload protection stops supply automatically during overheating. The dry motor uses pumped liquid for cooling up to 50°C.
Wear is controlled by the DRIVELUB SEAL SYSTEM, a multiple seal layout with an internal oil chamber. This merges a V-ring with a silicon carbide seal, creating a barrier against infiltration. The diffuser plate is coated with polyurethane for abrasion resistance. Fluid is driven by an open impeller through a 32 mm inlet and exits via a 32 mm outlet.
Weighing 12 kg, the unit supports stable positioning. A pre-assembled float switch governs operation, activating at a minimum liquid depth of 25 mm. The casing delivers IPX8 protection for submersion. Class F insulation secures the electrical layout alongside a 10-meter H07RN-F power cord, passing suspended solids up to 8 mm.
Features
