Constructed around an AISI 304 stainless steel housing, the DIWA7 grey water pump provides structural stability. Incorporating submersible pumps for clean and slightly dirty water manufactured in AISI 304 stainless steel, this unit handles fluid tasks. The casing is engineered to assist the emptying of tanks and lawn irrigation.
This single-phase 240v unit utilizes a 0.75 kW motor drawing 6.2 Amps. The system achieves a max flow of approximately 325 L/Min and projects liquid to a max head of 11.2 m. The dry motor is actively cooled by the pumped liquid, permitting activation provided the temperature stays below 50°C. A built-in capacitor assists starting.
The assembly employs the DRIVELUB SEAL SYSTEM, utilizing a V-ring alongside a silicon carbide mechanical seal within an oil chamber. The diffuser plate is heavily coated with polyurethane, supplying resistance to abrasion. Liquid enters through a 32 mm base inlet and exits via a 32 mm threaded outlet, accommodating suspended solids up to 8 mm.
With a net weight of 14.3 kg, the device provides reliable positioning. The unit is fitted with a 10-meter H07RN-F power cord and delivers IPX8 protection for absolute submersion. A pre-assembled float switch manages automatic activation at a minimum level of 25 mm. Class F insulation ensures the electrical layout remains completely secure.
