ScaleBlaster is a product that eliminates the formation of limestone deposits in water pipes, faucets, cooling towers and boilers without the need for water softening equipment, salts, chemicals or maintenance. The integrated circuitry system produces a complex modulating frequency waveform that hits the resonant frequency of the calcium carbonate molecules, causing them to lose their adhesive properties. The product is non-invasive.

Medium-speed Vertical Pump

The pump division of Flowserve Corporation has published a new eight page full color brochure that describes its new medium speed pump (MSP), a variable speed, vertical inline pump. Featuring an Eexd(e) II C T4 explosive proof motor for hazardous environments, the MSP can be controlled by motor speed (frequency) or by an integrated PI controller that responds to physical parameters such as pressure and flow. Motor ratings range from 22 to 80 kW (30 to 107 hp).

Automated Lubrication System

John Crane Safematic’s Safegrease 2 Automated Lubrication System monitors equipment to determine exactly when, where and how much grease lubrication is needed. If required the system delivers the correct amount of lubricant to the specific machinery indicated. The system extends equipment life and reduces energy consumption. In addition, because no manual lubrication is required, the possibility of accidents is reduced.
