Griffin Pump
Griffin’s Model 18 NCRD pumps are capable of delivering flows exceeding 17,000 gallons per minute and providing head capacities of 240 feet or more. Griffin non-clog pumps are an ideal solution for sewer bypasses, flood control, sumping, or any other application requiring high volume and the ability to move trash laden effluent. It features a non–clog impeller capable of handling stringy materials and solids up to 4.5 inches and a large clean out/inspection port for hassle-free removal of large debris over 4.5 inches without removing suction pipe or hose. These pumps are available in vacuum-assist, diaphragm prime or compressor prime with either electric or diesel powered engines. 866.770.8100, griffinpump.com
Subaru/Robin America
Subaru’s high-pressure pump combines a powerful overhead-cam engine with high-pressure capabilities and heavy-duty construction to deliver the performance needed for a variety of applications. Powered by a 6.0-hp Subaru EX17 engine, the two-inch PKX201H offers a lift height of up to 275 feet and a maximum delivery volume of 127 gallons per minute. A hardened cast-iron volute effectively withstands suspended particles and small solids sucked through the strainer, while an abrasion-resistant, cast-iron three-blade impeller and a replaceable wear plate ensure long life and low maintenance. The automatic decompression, easy-pull recoil starter and Hot Spark ignition system provide easy and reliable starting. The large-capacity fuel tank extends operation time, while its special coating helps prevent rust from forming inside the tank. 847.540.7300, subarupower.com
Gorman-Rupp Pumps
The Gorman-Rupp line of Prime Aire Plus pumps employ the same venturi/compressor priming system as the Prime Aire line. Increased head, flow and enhanced maintenance features are additional benefits of the pumps. Models feature up to 8-inch flanged discharge sizes, provide flows up to 4,950 gpm and heads to 475 feet. 419.755.1011, GRpumps.com
Thompson Pump & Mfg.
The new Compact pump series boast the benefits of a smaller compact size, lighter weight, fewer parts, less maintenance and lower price. The Thompson Compact pump is 35 percent smaller and 20 percent lighter but offers the same performance as a standard size pump with 24-hour run time fuel tank. Available in the most common diesel-drive portable pump sizes of 4 and 6 inches, the Compact series offers an economical alternative to similar sized portable pumps – a significant savings compared to standard compressor-assisted pumps. The Compact pump series includes the Enviroprime system, which keeps the pumpage from discharging into the environment. It also has automatic start/stop and Silent Knight sound attenuation. 800.767.7310, thompsonpump.com
Rain for Rent
The HH-125c 4-inch pump is designed to produce high flow and high discharge head for various applications such as dewatering mines and quarries. The HH-125c also functions as a force main sewer bypass pump and handles solids to 3-inch diameter. Capable of flows to 1,525 gpm and 325-foot discharge head, this pump is ideal for high head applications. With hydraulic efficiency at 78 percent, this pump moves more water at a lower cost per gallon pumped. Mounted on a galvanized trailer or skid to protect against rust and corrosion, this equipment has a nearly maintenance free surface. An electric motor driven option is also available. 800.742.7246, www.rainforrent.com
Grindex Pumps
Grindex Pumps offers professional dewatering pumps from 0.6 to 140 hp, capacities up to 5,000 gpm and 750 feet. With built-in controls, SMART Motor protection and air valve for dry running, the Grindex pumps will not run backwards, will not single phase and will not overheat. We call it “Trouble Free Dewatering”. 708.781.2135, grindex.com/us
Godwin
The Godwin Dri-Prime NC80 is a compact pump with flow capabilities up to 609 gpm and discharge heads up to 105 feet. The NC80 features patented Flygt N-technology with an innovative self-cleaning hydraulic. This makes the NC80 a best-in-class portable pump suitable for tough sewage and sludge applications. The Dri-Prime automatic self-priming system primes and re-primes from dry up to 28 feet without operator assistance or foot valve control. Other features include a Hard-Iron (60 HRC) impeller and insert ring; dry-running high-pressure oil bath mechanical seal with highly abrasion-resistant silicon carbide faces; and close-coupled centrifugal pump mounted to a diesel engine or electric motor for easy pumpend or engine/motor changeover in the field. 856.467.3636, godwinpumps.com
Allegro Industries
Five models of Dewatering and Sludge Pumps offer continuous operation at low water levels and extended dry runs without overheating the motor. These portable, submergible pumps are excellent for manholes, vaults, construction sites and all dewatering needs. The new DC Submersible Dewatering Pump is a totally enclosed, submersible dewatering unit. Watertight o-ring seals keep pump’s internal parts completely dry and it delivers up to 43 gallons per minute for rapid dewatering and instant prime. It can operate on any 12 volt truck or automobile battery, and the low 30 AMP draw allows for an hour of operation without starting the engine. 800.622.3530, allegrosafety.com
