Product Overview
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.
Features
- Manufactured utilizing EN 10088-1-X5CrNi18-10 stainless steel for the structural shaft end and hardware.

What operating liquid temperature range and maximum immersion depth in meters are supported by this submersible dewatering drainage pump?
Operating under submerged drainage conditions, the DIWA7 sustains a maximum 7 m immersion depth across fluid operating temperatures up to 40°C and accommodates 8 mm suspended solids.
How much fluid elevation head can this submersible dewatering drainage pump generate upward across pipe runs?
Providing in multi-story elevation loops, the DIWA-7 maintains a maximum dynamic head of approximately 11.2 m across vertical piping.
Through its flow assembly, what maximum delivery volume and discharge pipe diameter does this submersible dewatering drainage pump output?
Dispatching into building service circuits, the DIWA 7 outputs a peak liquid flow volume of approximately 325 L/Min through Rp 1-1/2" (40 mm) discharge threaded port.
What structural alloy metallurgy and mechanical face seal materials safeguard this submersible dewatering drainage pump against corrosion?
Formed against fluid chemical attack, the DIWA_7 utilizes alloy construction of AISI 304 stainless steel pump casing, diffusers, and polyurethane-coated open impeller backed by mechanical face seals to prevent fluid corrosion.
What electrical operating voltage and motor power rating in kilowatts are certified on this submersible dewatering drainage pump?
Incorporating under nominal voltage supply, the DIWA7 operates via an electric motor rated at 0.75 kW (1.0 HP) on a supply voltage of 220–240 V, 50 Hz, single-phase at 6.2 A.
