www.rockproducts.com ROCK products • April 2019 • 43 EQUIPMENT & TECHNOLOGY PUMPS & MOTORS Chicago Pneumatic Power Technique (CP) introduced five new electric submersible pumps to the North American market. WEDA pumps are ideal for dewatering of construction sites, mines, flooded areas and more where small, lightweight, portable and easily main- tained pumps are required to perform daily jobs quickly. Designed for handling liquid with abrasive par- ticles, the five submersible pumps include the WEDA 10, 30, 40, 50+ and 60+. They provide fast and efficient dewatering for a wide variety of applica- tions, including excavations in construction areas, general dewatering requirements at mines, shipyards and other industrial sites, fire brigades, utility installations and repairs, maintenance and cleanup tasks in urban areas, and govern- ment and military response and preparedness programs. Features of each pump include: • Robust design. • Lightweight and user friendly. •  Wear resistant wet end in CR-alloy steel and natural rubber. • Adjustable wear parts. • Complete seal pack for easy and fast service. • Built-in capacitor and contractor. • Easy installation. "We are excited to launch this line of WEDA pumps into the market and believe these will be crucial on job sites span- ning several different markets," said Joe Moser, product manager — pumps at CP. "These pumps were designed with the customer in mind. For as lightweight and small as they are, it is an incredibly durable and wear resistant line that customers will have tremendous success with." Chicago Pneumatic, www.cp.com Rain for Rent Pumps Save Quarry A low-pressure weather system over the southeastern Appalachian Moun- tains brought heavy, intense rains that caused a creek to break through a berm and flood a quarry that provided aggregates essential to the construction industry. An estimated six billion gal. of water shut down the quarry's crusher and conveyor. With the devastation from the flooding in the surrounding communities, the company needed to dewater and get production back on line to meet the increased demand. Rain for Rent was contacted to dewater the quarry. After a site survey, it was determined that an initial 100-ft. of dewatering was most critical to getting the crusher back up and running. Once the plant was back in production, the remaining 300- ft. of water could be pumped out of the pit at a slower, more cost-effective pace. A system consisting of three DV400c 16-in. pumps, 18-in. HDPE suction stingers and discharge piping allowed for the periodic repositioning of the pumps was mobilized. Technicians fused pipe on site and assisted the quarry personnel in positioning the pumps, a difficult task since the breach in the berm had to be repaired prior to staging the pumps. Even with the massive equipment for moving rock into the berm hole, the task took several days. Pumping at a rate of nearly 40,000 gpm, the water level in the pit began to subside. The pumps were routinely repositioned deeper into the quarry as the water level dropped to limit the suc- tion lift to no more than 18-ft. Strong teamwork between the aggre- gate company and Rain for Rent resulted in a successful, timely solution, saving the quarry money and prevent- ing permanent damage to the flooded crusher and conveyer equipment.
