Grindex Pumps drainage/sludge pumps
Grindex Pumps introduces a new generation of submersible heavy-duty drainage/sludge pumps for construction, tunneling and other industries.
A "SMART" Motor Protection feature prevents Grindex pumps from single phasing, overheating and backward rotation. Only Grindex has the patented Air Valve system that allows their pump to run completely dry without damage. A newly designed hydraulics section with a closed impeller reduces the performance drop caused by long-term wear. The impeller is easily adjusted, ensuring stable dewatering during the whole life of the pump. Designs range from 1.9 to 140 hp, delivering between 155 and 5,000 gpm. 708.532.9988, www.grindex.com/us
