Fuels and Firing Centrifugal Pump is the Answer This versatile pump, simple and sturdy in design, is an entirely self-contained unit. Its close-coupled design elimi nates coupling and assures perfect alignment with freedom from vibration. The "Closc-Cupld" needs no space consuming special foundation ... no unwieldy base plate to support pump and motor. As a result, installation costs are low. Hundreds of those pumps are doing u wide variety of jobs in factories, steel mills and cltemical plants. Interchange able parts keep inventories low. Avail able in a wide variety of sizes.
