• Garden and lawn irrigation, with suction from rainwater tanks.
• Emergency draining of flooded basements, garages and cellars.
• Transfer of water from tanks, cisterns and swimming pools.
Specifications
• Maximum liquid temperature: 40°C with partially submerged pump.
• Dry motor.
• Maximum immersion depth: 5 m..
• Class B insulation.

The DOC 3 pump

has a capacity of 145 l/min, head up to 7 m, and passes suspended solids up to 10 mm in diameter. Singlephase version only.

The DOC 7 pump

has a capacity of 230 l/min, head up to 11m, and passes suspended solids up to 10 mm in diameter.

DOC3 and DOC7 models,

is available on request. It ensures complete drainage of flooded floors (to 3 mm from floor).

Versions:
Single-phase 220 V 50 Hz 2 poles (2850 rpm).
Three-phase 380-415 V 50 H 2 poles (2850 rpm). 60 Hz and floatless (SG) models are available on request.
The single-phase versions feature: Pre-assembled float for automatic pump operation (version without float available on request). Built-in capacitor. Thermal overload protection to stop pump supply in case of overheating.


LAB-LIP SEAL SYSTEM
The electric motor is protected by three lip seals. An impeller counterbladesystem keeps solid particles away from the seal unit to prevent damage to the lip seals and ensure their long-lasting efficiency. A double labyrinth and a V-ring on the shaft have also been provided.
