Description:
APPLICATIONS
• The Lowara GLV series submersible pumps are for pumping clean water, surface water
and wastewater containing solids or long-fibred material.
The vortex impeller is the best choice in low volume, high head applications and in media which contains sand and other abrasive solids.
