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
