GXR, GXV

Summary

Product Identification

These are Calpeda GXR and GXV series single-impeller submersible pumps, constructed from chrome-nickel stainless steel, featuring a vertical delivery port.

• GXR models: Equipped with an open impeller.
• GXV models: Equipped with a free-flow (vortex) impeller.

The motor is cooled by the pumped water circulating between the motor jacket and the external jacket. All models feature a double shaft seal with an oil chamber.

Applications

• GXR models:
  • For clean water containing solids up to 10 mm grain size.
  • Suitable for draining rooms or emptying tanks.
  • For extraction of water from ponds, streams, or pits and for rainwater collection.
  • For irrigation purposes.
• GXV models:
  • For clean or slightly dirty water, containing solids up to 25 mm grain size.
  • Particularly suitable for liquids with a high solid content.

For outdoor use, a power supply cable of not less than 10 m should be used in accordance with EN 60 335-2-41.
