DIWA Submersible Electric Pumps for drainage of clean and slightly dirty water

Submersible pumps for clean and slightly dirty water manufactured in AISI 304 stainless steel. Head up to 20 metres, delivery up to 420 l/min (25,2 m3/h). Four basic models with 0,55 to 1,5 kW. DRIVELUB SEAL SYSTEM. Diffuser plate coated with polyurethane for the maximum resistance to abrasion.

Applications
• Draining of cellars, garages, basements.
• Draining of construction sites.
• Emptying of tanks and reservoirs.
• Lawn and garden irrigation.
• Pumping of domestic wastewater washing machines, showers, sinks.
• Emptying of tanks in industrial and ecological applications.

Specifications
• Liquid temperature up to 50°C.
• Open impeller.
• Minimum level of pumped liquid: 25 mm.
• Suspended solids handled up to 8 mm in diameter.
• Maximum immersion depth: 7 m.
• 10 metres of H07RN-F type neoprene power cord.
• Dry motor (class F insulation) cooled by pumped liquid.

Versions
- Single-phase: 220-240 V, 50 Hz 2 poles with built-in thermal protector.
- Three-phase: 220-240 V, 50 Hz 380-415 V, 50 Hz 2 poles.
Motor power
- 0,55 to 1,1 kW for single-phase version.
- 0,55 to 1,5 kW for three-phase version.
• The single-phase versions features: Pre-assembled float (version without float available on request). Built-in capacitor (except DIWA 11
model with control box on cable). Thermal protector.
• 60 Hz and versions without float (SG) available.

DRIVELUB SEAL SYSTEM
• Watertight electric motor protected by multiple seal system with oilchamber. A V-ring and silicon carbide mechanical seal (extremely resistant to wear and abrasion), as well as a lip seal which is continuosly lubricated by the DRIVELUB system, provide an extreme barrier against infiltration.
