Bursting - Pow-r Mole Sales PD-7

The PD-7 static pipe bursting machine from Pow-r Mole Sales is designed to replace existing underground water, sewer or gas lines. It will operate from a pit only 72 inches long. Despite its small size, it has a pulling force of 112,000 pounds at 3,000 psi and a maximum pull rate of 7 feet per minute. This system uses a 2-inch-diameter rod with a tapered quick-connect thread in a length of 2 1/2 feet. It can be powered by a hydraulic power unit or from an auxiliary circuit on a backhoe. It can burst and install up to 12-inch I.D. pipe in most compressible soils. 800/344-6653; www.powrmole.com.
