Application

The A 2 poles Series is used in pumping and draining clear liquids and sewage. High performance renders it useful in a variety of applications: water treatment plants, industrial plants, farms and sewers.

Characteristic

All main components are made of grey cast ironGG25. Two individual mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid) and high quality parts, ensure the perfect functioning and reliability of the product.

Motor range

• Squirrel cage motor at 2 poles
• Thermal protection T1 and T2 embedded in the motor winding (to be wired to the three pole contactor in the control panel)
• Class F insulation (155°C)
• IP 68 protection

Motor cooling

The cooling of the motor is ensured by the liquid where the pump is submerged.

Limits of use

• Max. permissible liquid temperature: 40°C with pump fully submerged
• On request, special version (excluded ATEX) to withstand liquid temperature up to 60°C with pump fully submerged, no S1 service
• Maximum depth of immersion: 20 MT.
• Permissible pH value: 6-10
• Hydraulic features suitable for liquids with density <1,1 kg/dm3
• Allowed voltage: 230/400V or 400/690V±5% depending on the pump
• Allowed frequency: 50Hz ±2%
