The DD-6 pump from Myers Seth Pump pulls the best attributes of four different types of pumps — double diaphragm, centrifugal, piston and rotary lobe — into one solution. The DD-6 is capable of being used for the six most common methods of de-watering that are typically encountered on a job site, from simple to complex. The 6-inch, high-volume, double-diaphragm pump has a HATZ 1D81Z, 10 hp air-cooled diesel engine, enabling 140 max cfm. It features high head pressure and 3/8-inch steel construction to make it reliable and durable. It can pump 700 gpm, deliver 28 feet of vertical lift and move 4 1/2-inch solids, making it a great sludge and slurry pump as well. The Sound Attenuated Fully Enclosed version reduces noise output by up to 50%, making it ideal for metropolitan and urban environments. 904-389-6114; www.myerssethpumps.com.
