V4 up to 55 kW

Application
The VT 4 poles Series is used for transport of water with heavy suspended solids. High performance and a wide channel permits it’s use in industry, including tanneries and farms, and for the movement of water contaminated with soil, or containing large solid pieces.

Characteristic
All main components are made of grey cast iron GG25. 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 4 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: 400/690V ±5%
• Allowed frequency: 50Hz ±2%

Impellers
Impellers have been studied to grant excellent performances and ample solid handling.

Explosion proof pumps
These certificates grant for the safe use of the product in hazardous area in line with the stringent European and International standards ATEX/IECEx.

Seal leak detector
The seal leak detector is certified according to the norm EN 60079-0, EN 60079-1 (through safety barrier). Standard on all series (not applicable with IECEx).

Bearings
The series is fitted with a cylindrical roller bearing (upper bearing) to absorb the thrust and vibration generated by the pump shaft.
