GX

Application

The G2 poles Series have an inbuilt macerator in the inlet. This breaks down solids in waste water which permits transport along relatively narrow, often pre-existing, pipes. Applications: domestic sewage, liquids with suspended solids, whenever high pressure (Hm) is needed.

Characteristic

The main components are fabricated in cast iron GG20 In the standard configuration a lip seal in oil chamber, is fitted to the motor side, and a mechanical seal to the impeller side.

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: 230V/400V ±5%
•  Allowed frequency: 50Hz ±2%

Grinding system
The pump has a macerator in the inlet with axial cutting action. The blades are made of hardened steel guaranteeing maximal cutting efficiency.

Explosion proof pumps
Pumps with explosion proof available on request.
