Submersible mixers from KSB have propellers that have been optimized to transfer the maximum amount of energy to the fluid while consuming the least amount of power. Their tandem mechanical sealing arrangement provides a 100 percent backup system to seal the shaft, while the leak-proof cable entry prevents water from wicking inside the motor. Their cable plug allows for easy installation and removal of the mixer. Just plug it in or unplug it without the assistance of an electrician. The design provides reliable service for demanding applications, which allows users to focus on plant operations instead of mixer maintenance. 804/222-1818; www.ksbusa.com
