2 Translating user requirements into product features After some 5 years of designing and manufacturing submersible electrical dewatering pumps and listening to the customers, Grindex now offers a completely new generation of permissible drainage and sludge pumps approved by MSA. The nine new pumps in the range have an output of 2-58 P and cover applications requiring MSA approved permissible pumps in mining and tunneling where explosive or gassy environments might appear. The new pumps are designed to dramatically reduce operational costs. Air valve cools the pump should it run dry MSA-approved pumps for use in gassy mines or tunnels Wear protector system provides better wear resistance Checking avoid costly repairs Easy maintenance service one, service all Easy to service lasting performance
