GRIX

Application

The Grix range of submersible pumps 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 The configuration has a lip seal fitted to the motor side, and a mechanical seal in oil chamber, on the impeller side

Motor range

• Squirrel cage motor in 2 poles version
• Thermal protection embedded in the winding
• Insulation class F 155°C
• Motor protection IP 68

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.
•  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%

Grinder system
The pump has a radial macerator in the inlet. The blades are made of hardened steel guaranteeing maximal cutting efficiency.
